Element <mets>

METS: Metadata Encoding and Transmission Standard. METS is intended to provide a standardized XML format for transmission of complex digital library objects between systems. As such, it can be seen as filling a role similar to that defined for the Submission Information Package (SIP), Archival Information Package (AIP) and Dissemination Information Package (DIP) in the Reference Model for an Open Archival Information System. The root element <mets> establishes the container for the information being stored and/or transmitted by the standard.

Element <dmdSec>

type="mdSecType" minOccurs="0" maxOccurs="unbounded"
A descriptive metadata section <dmdSec> records descriptive metadata pertaining to the METS object as a whole or one of its components. The <dmdSec> element conforms to same generic datatype as the <techMD>, <rightsMD>, <sourceMD> and <digiprovMD> elements, and supports the same sub-elements and attributes. A descriptive metadata element can either wrap the metadata (mdWrap) or reference it in an external location (mdRef) or both. METS allows multiple <dmdSec> elements; and descriptive metadata can be associated with any METS element that supports a DMDID attribute. Descriptive metadata can be expressed according to many current description standards (i.e., MARC, MODS, Dublin Core, TEI Header, EAD, VRA, FGDC, DDI) or a locally produced XML schema.

Element <amdSec>

type="amdSecType" minOccurs="0" maxOccurs="unbounded"
The administrative metadata section <amdSec> contains the administrative metadata pertaining to the digital object, its components and any original source material from which the digital object is derived. The <amdSec> is separated into four sub-sections that accommodate technical metadata (techMD), intellectual property rights (rightsMD), analog/digital source metadata (sourceMD), and digital provenance metadata (digiprovMD). Each of these subsections can either wrap the metadata (mdWrap) or reference it in an external location (mdRef) or both. Multiple instances of the <amdSec> element can occur within a METS document and multiple instances of its subsections can occur in one <amdSec> element. This allows considerable flexibility in the structuring of the administrative metadata. METS does not define a vocabulary or syntax for encoding administrative metadata. Administrative metadata can be expressed within the amdSec sub-elements according to many current community defined standards, or locally produced XML schemas.

Element <fileGrp>

maxOccurs="unbounded"
A sequence of file group elements <fileGrp> can be used group the digital files comprising the content of a METS object either into a flat arrangement or, because each file group element can itself contain one or more file group elements, into a nested (hierarchical) arrangement. In the case where the content files are images of different formats and resolutions, for example, one could group the image content files by format and create a separate <fileGrp> for each image format/resolution such as: - one <fileGrp> for the thumbnails of the images - one <fileGrp> for the higher resolution JPEGs of the image - one <fileGrp> for the master archival TIFFs of the images For a text resource with a variety of content file types one might group the content files at the highest level by type, and then use the <fileGrp> element’s nesting capabilities to subdivide a <fileGrp> by format within the type, such as: - one <fileGrp> for all of the page images with nested <fileGrp> elements for each image format/resolution (tiff, jpeg, gif) - one <fileGrp> for a PDF version of all the pages of the document - one <fileGrp> for a TEI encoded XML version of the entire document or each of its pages. A <fileGrp> may contain zero or more <fileGrp> elements and or <file> elements.

USE: xsd:string   optional  
USE (string/O): A tagging attribute to indicate the intended use of files within this file group (e.g., master, reference, thumbnails for image files). A USE attribute can be expressed at the<fileGrp> level, the <file> level, the <FLocat> level and/or the <FContent> level. A USE attribute value at the <fileGrp> level should pertain to all of the files in the <fileGrp>. A USE attribute at the <file> level should pertain to all copies of the file as represented by subsidiary <FLocat> and/or <FContent> elements. A USE attribute at the <FLocat> or <FContent> level pertains to the particular copy of the file that is either referenced (<FLocat>) or wrapped (<FContent>).

Element <structMap>

type="structMapType" maxOccurs="unbounded"
The structural map section <structMap> is the heart of a METS document. It provides a means for organizing the digital content represented by the <file> elements in the <fileSec> of the METS document into a coherent hierarchical structure. Such a hierarchical structure can be presented to users to facilitate their comprehension and navigation of the digital content. It can further be applied to any purpose requiring an understanding of the structural relationship of the content files or parts of the content files. The organization may be specified to any level of granularity (intellectual and or physical) that is desired. Since the <structMap> element is repeatable, more than one organization can be applied to the digital content represented by the METS document. The hierarchical structure specified by a <structMap> is encoded as a tree of nested <div> elements. A <div> element may directly point to content via child file pointer <fptr> elements (if the content is represented in the <fileSec<) or child METS pointer <mptr> elements (if the content is represented by an external METS document). The <fptr> element may point to a single whole <file> element that manifests its parent <div<, or to part of a <file> that manifests its <div<. It can also point to multiple files or parts of files that must be played/displayed either in sequence or in parallel to reveal its structural division. In addition to providing a means for organizing content, the <structMap> provides a mechanism for linking content at any hierarchical level with relevant descriptive and administrative metadata.

ID (ID/O): This attribute uniquely identifies the element within the METS document, and would allow the element to be referenced unambiguously from another element or document via an IDREF or an XPTR. For more information on using ID attributes for internal and external linking see Chapter 4 of the METS Primer.
TYPE: xsd:string   optional  
TYPE (string/O): Identifies the type of structure represented by the <structMap>. For example, a <structMap> that represented a purely logical or intellectual structure could be assigned a TYPE value of “logical” whereas a <structMap> that represented a purely physical structure could be assigned a TYPE value of “physical”. However, the METS schema neither defines nor requires a common vocabulary for this attribute. A METS profile, however, may well constrain the values for the <structMap> TYPE.
LABEL: xsd:string   optional  
LABEL (string/O): Describes the <structMap> to viewers of the METS document. This would be useful primarily where more than one <structMap> is provided for a single object. A descriptive LABEL value, in that case, could clarify to users the purpose of each of the available structMaps.

Element <structLink>

minOccurs="0"
The structural link section element <structLink> allows for the specification of hyperlinks between the different components of a METS structure that are delineated in a structural map. This element is a container for a single, repeatable element, <smLink> which indicates a hyperlink between two nodes in the structural map. The <structLink> section in the METS document is identified using its XML ID attributes.

Element <behaviorSec>

type="behaviorSecType" minOccurs="0" maxOccurs="unbounded"
A behavior section element <behaviorSec> associates executable behaviors with content in the METS document by means of a repeatable behavior <behavior> element. This element has an interface definition <interfaceDef> element that represents an abstract definition of the set of behaviors represented by a particular behavior section. A <behavior> element also has a <mechanism> element which is used to point to a module of executable code that implements and runs the behavior defined by the interface definition. The <behaviorSec> element, which is repeatable as well as nestable, can be used to group individual behaviors within the structure of the METS document. Such grouping can be useful for organizing families of behaviors together or to indicate other relationships between particular behaviors.

A digital provenance metadata element <digiprovMD> can be used to record any preservation-related actions taken on the various files which comprise a digital object (e.g., those subsequent to the initial digitization of the files such as transformation or migrations) or, in the case of born digital materials, the files’ creation. In short, digital provenance should be used to record information that allows both archival/library staff and scholars to understand what modifications have been made to a digital object and/or its constituent parts during its life cycle. This information can then be used to judge how those processes might have altered or corrupted the object’s ability to accurately represent the original item. One might, for example, record master derivative relationships and the process by which those derivations have been created. Or the <digiprovMD> element could contain information regarding the migration/transformation of a file from its original digitization (e.g., OCR, TEI, etc.,)to its current incarnation as a digital object (e.g., JPEG2000). The <digiprovMD> element conforms to same generic datatype as the <dmdSec>, <techMD>, <rightsMD>, and <sourceMD> elements, and supports the same sub-elements and attributes. A digital provenance metadata element can either wrap the metadata (mdWrap) or reference it in an external location (mdRef) or both. METS allows multiple <digiprovMD> elements; and digital provenance metadata can be associated with any METS element that supports an ADMID attribute. Digital provenance metadata can be expressed according to current digital provenance description standards (such as PREMIS) or a locally produced XML schema.

attributes

ID: xsd:ID   required  
ID (ID/R): This attribute uniquely identifies the element within the METS document, and would allow the element to be referenced unambiguously from another element or document via an IDREF or an XPTR. The ID attribute on the <dmdSec>, <techMD>, <sourceMD>, <rightsMD> and <digiprovMD> elements (which are all of mdSecType) is required, and its value should be referenced from one or more DMDID attributes (when the ID identifies a <dmdSec> element) or ADMID attributes (when the ID identifies a <techMD>, <sourceMD>, <rightsMD> or <digiprovMD> element) that are associated with other elements in the METS document. The following elements support references to a <dmdSec> via a DMDID attribute: <file>, <stream>, <div>. The following elements support references to <techMD>, <sourceMD>, <rightsMD> and <digiprovMD> elements via an ADMID attribute: <metsHdr>, <dmdSec>, <techMD>, <sourceMD>, <rightsMD>, <digiprovMD>, <fileGrp>, <file>, <stream>, <div>, <area>, <behavior>. For more information on using ID attributes for internal and external linking see Chapter 4 of the METS Primer.
GROUPID: xsd:string   optional  
GROUPID (string/O): This identifier is used to indicate that different metadata sections may be considered as part of a group. Two metadata sections with the same GROUPID value are to be considered part of the same group. For example this facility might be used to group changed versions of the same metadata if previous versions are maintained in a file for tracking purposes.
ADMID: xsd:IDREFS   optional  
ADMID (IDREFS/O): Contains the ID attribute values of the <digiprovMD>, <techMD>, <sourceMD> and/or <rightsMD> elements within the <amdSec> of the METS document that contain administrative metadata pertaining to the current mdSecType element. Typically used in this context to reference preservation metadata (digiprovMD) which applies to the current metadata. For more information on using METS IDREFS and IDREF type attributes for internal linking, see Chapter 4 of the METS Primer.
CREATED: xsd:dateTime   optional  
CREATED (dateTime/O): Specifies the date and time of creation for the metadata.
STATUS: xsd:string   optional  
STATUS (string/O): Indicates the status of this metadata (e.g., superseded, current, etc.).

For more information on using ID attributes for internal and external linking see Chapter 4 of the METS Primer.
VERSDATE: xsd:dateTime   optional  
VERSDATE (dateTime/O): An optional dateTime attribute specifying the date this version/fileGrp of the digital object was created.
ADMID: xsd:IDREFS   optional  
ADMID (IDREF/O): Contains the ID attribute values of the <techMD>, <sourceMD>, <rightsMD> and/or <digiprovMD> elements within the <amdSec> of the METS document applicable to all of the files in a particular file group. For more information on using METS IDREFS and IDREF type attributes for internal linking, see Chapter 4 of the METS Primer.
USE: xsd:string   optional  
USE (string/O): A tagging attribute to indicate the intended use of files within this file group (e.g., master, reference, thumbnails for image files). A USE attribute can be expressed at the<fileGrp> level, the <file> level, the <FLocat> level and/or the <FContent> level. A USE attribute value at the <fileGrp> level should pertain to all of the files in the <fileGrp>. A USE attribute at the <file> level should pertain to all copies of the file as represented by subsidiary <FLocat> and/or <FContent> elements. A USE attribute at the <FLocat> or <FContent> level pertains to the particular copy of the file that is either referenced (<FLocat>) or wrapped (<FContent>).

Element <file>

minOccurs="0" maxOccurs="unbounded" type="fileType"
The file element <file> provides access to the content files for the digital object being described by the METS document. A <file> element may contain one or more <FLocat> elements which provide pointers to a content file and/or a <FContent> element which wraps an encoded version of the file. Embedding files using <FContent> can be a valuable feature for exchanging digital objects between repositories or for archiving versions of digital objects for off-site storage. All <FLocat> and <FContent> elements should identify and/or contain identical copies of a single file. The <file> element is recursive, thus allowing sub-files or component files of a larger file to be listed in the inventory. Alternatively, by using the <stream> element, a smaller component of a file or of a related file can be placed within a <file> element. Finally, by using the <transformFile> element, it is possible to include within a <file> element a different version of a file that has undergone a transformation for some reason, such as format migration.
may contain | <FLocat> | <FContent> | <stream> | <transformFile> | <file>

attributes

ID: xsd:ID   required  
ID (ID/R): This attribute uniquely identifies the element within the METS document, and would allow the element to be referenced unambiguously from another element or document via an IDREF or an XPTR. Typically, the ID attribute value on a <file> element would be referenced from one or more FILEID attributes (which are of type IDREF) on <fptr>and/or <area> elements within the <structMap>. Such references establish links between structural divisions (<div> elements) and the specific content files or parts of content files that manifest them. For more information on using ID attributes for internal and external linking see Chapter 4 of the METS Primer.
SEQ: xsd:int   optional  
SEQ (integer/O): Indicates the sequence of this <file> relative to the others in its <fileGrp>.
OWNERID: xsd:string   optional  
OWNERID (string/O): A unique identifier assigned to the file by its owner. This may be a URI which differs from the URI used to retrieve the file.
ADMID: xsd:IDREFS   optional  
ADMID (IDREFS/O): Contains the ID attribute values of the <techMD>, <sourceMD>, <rightsMD> and/or <digiprovMD> elements within the <amdSec> of the METS document that contain administrative metadata pertaining to the file. For more information on using METS IDREFS and IDREF type attributes for internal linking, see Chapter 4 of the METS Primer.
DMDID: xsd:IDREFS   optional  
DMDID (IDREFS/O): Contains the ID attribute values identifying the <dmdSec>, elements in the METS document that contain or link to descriptive metadata pertaining to the content file represented by the current <file> element. For more information on using METS IDREFS and IDREF type attributes for internal linking, see Chapter 4 of the METS Primer.
GROUPID: xsd:string   optional  
GROUPID (string/O): An identifier that establishes a correspondence between this file and files in other file groups. Typically, this will be used to associate a master file in one file group with the derivative files made from it in other file groups.
USE: xsd:string   optional  
USE (string/O): A tagging attribute to indicate the intended use of all copies of the file aggregated by the <file> element (e.g., master, reference, thumbnails for image files). A USE attribute can be expressed at the<fileGrp> level, the <file> level, the <FLocat> level and/or the <FContent> level. A USE attribute value at the <fileGrp> level should pertain to all of the files in the <fileGrp>. A USE attribute at the <file> level should pertain to all copies of the file as represented by subsidiary <FLocat> and/or <FContent> elements. A USE attribute at the <FLocat> or <FContent> level pertains to the particular copy of the file that is either referenced (<FLocat>) or wrapped (<FContent>).
BEGIN: xsd:string   optional  
BEGIN (string/O): An attribute that specifies the point in the parent <file> where the current <file> begins. When used in conjunction with a <file> element, this attribute is only meaningful when this element is nested, and its parent <file> element represents a container file. It can be used in conjunction with the END attribute as a means of defining the location of the current file within its parent file. However, the BEGIN attribute can be used with or without a companion END attribute. When no END attribute is specified, the end of the parent file is assumed also to be the end point of the current file. The BEGIN and END attributes can only be interpreted meaningfully in conjunction with a BETYPE attribute, which specifies the kind of beginning/ending point values that are being used.
END: xsd:string   optional  
END (string/O): An attribute that specifies the point in the parent <file> where the current, nested <file> ends. It can only be interpreted meaningfully in conjunction with the BETYPE, which specifies the kind of ending point values being used. Typically the END attribute would only appear in conjunction with a BEGIN attribute.
BETYPE:   optional   | BYTE
BETYPE: Begin/End Type. BETYPE (string/O): An attribute that specifies the kind of BEGIN and/or END values that are being used. Currently BYTE is the only valid value that can be used in conjunction with nested <file> or <stream> elements.

Element <div>

type="divType"
The structural divisions of the hierarchical organization provided by a <structMap> are represented by division <div> elements, which can be nested to any depth. Each <div> element can represent either an intellectual (logical) division or a physical division. Every <div> node in the structural map hierarchy may be connected (via subsidiary <mptr> or <fptr> elements) to content files which represent that div's portion of the whole document.
may contain | <mptr> | <fptr> | <div>
contained within | <structMap> | <div> | <div>

attributes

ID: xsd:ID   optional  
ID (ID/O): This attribute uniquely identifies the element within the METS document, and would allow the element to be referenced unambiguously from another element or document via an IDREF or an XPTR. For more information on using ID attributes for internal and external linking see Chapter 4 of the METS Primer.
ORDER: xsd:integer   optional  
ORDER (integer/O): A representation of the div's order among its siblings (e.g., its absolute, numeric sequence). For an example, and clarification of the distinction between ORDER and ORDERLABEL, see the description of the ORDERLABEL attribute.
ORDERLABEL: xsd:string   optional  
ORDERLABEL (string/O): A representation of the div's order among its siblings (e.g., “xii”), or of any non-integer native numbering system. It is presumed that this value will still be machine actionable (e.g., it would support ‘go to page ___’ function), and it should not be used as a replacement/substitute for the LABEL attribute. To understand the differences between ORDER, ORDERLABEL and LABEL, imagine a text with 10 roman numbered pages followed by 10 arabic numbered pages. Page iii would have an ORDER of “3”, an ORDERLABEL of “iii” and a LABEL of “Page iii”, while page 3 would have an ORDER of “13”, an ORDERLABEL of “3” and a LABEL of “Page 3”.
LABEL: xsd:string   optional  
LABEL (string/O): An attribute used, for example, to identify a <div> to an end user viewing the document. Thus a hierarchical arrangement of the <div> LABEL values could provide a table of contents to the digital content represented by a METS document and facilitate the users’ navigation of the digital object. Note that a <div> LABEL should be specific to its level in the structural map. In the case of a book with chapters, the book <div> LABEL should have the book title and the chapter <div>; LABELs should have the individual chapter titles, rather than having the chapter <div> LABELs combine both book title and chapter title . For further of the distinction between LABEL and ORDERLABEL see the description of the ORDERLABEL attribute.
DMDID: xsd:IDREFS   optional  
DMDID (IDREFS/O): Contains the ID attribute values identifying the <dmdSec>, elements in the METS document that contain or link to descriptive metadata pertaining to the structural division represented by the current <div> element. For more information on using METS IDREFS and IDREF type attributes for internal linking, see Chapter 4 of the METS Primer.
ADMID: xsd:IDREFS   optional  
ADMID (IDREFS/O): Contains the ID attribute values identifying the <rightsMD>, <sourceMD>, <techMD> and/or <digiprovMD> elements within the <amdSec> of the METS document that contain or link to administrative metadata pertaining to the structural division represented by the <div> element. Typically the <div> ADMID attribute would be used to identify the <rightsMD> element or elements that pertain to the <div>, but it could be used anytime there was a need to link a <div> with pertinent administrative metadata. For more information on using METS IDREFS and IDREF type attributes for internal linking, see Chapter 4 of the METS Primer.
TYPE: xsd:string   optional  
TYPE (string/O): An attribute that specifies the type of structural division that the <div> element represents. Possible <div> TYPE attribute values include: chapter, article, page, track, segment, section etc. METS places no constraints on the possible TYPE values. Suggestions for controlled vocabularies for TYPE may be found on the METS website.
CONTENTIDS: URIs   optional  
CONTENTIDS (URI/O): Content IDs for the content represented by the <div> (equivalent to DIDL DII or Digital Item Identifier, a unique external ID).
: xlink:label    
xlink:label - an xlink label to be referred to by an smLink element

Element <mptr>

minOccurs="0" maxOccurs="unbounded"
Like the <fptr> element, the METS pointer element <mptr> represents digital content that manifests its parent <div> element. Unlike the <fptr>, which either directly or indirectly points to content represented in the <fileSec> of the parent METS document, the <mptr> element points to content represented by an external METS document. Thus, this element allows multiple discrete and separate METS documents to be organized at a higher level by a separate METS document. For example, METS documents representing the individual issues in the series of a journal could be grouped together and organized by a higher level METS document that represents the entire journal series. Each of the <div> elements in the <structMap> of the METS document representing the journal series would point to a METS document representing an issue. It would do so via a child <mptr> element. Thus the <mptr> element gives METS users considerable flexibility in managing the depth of the <structMap> hierarchy of individual METS documents. The <mptr> element points to an external METS document by means of an xlink:href attribute and associated XLink attributes.

Element <fptr>

minOccurs="0" maxOccurs="unbounded"
The <fptr> or file pointer element represents digital content that manifests its parent <div> element. The content represented by an <fptr> element must consist of integral files or parts of files that are represented by <file> elements in the <fileSec>. Via its FILEID attribute, an <fptr> may point directly to a single integral <file> element that manifests a structural division. However, an <fptr> element may also govern an <area> element, a <par>, or a <seq> which in turn would point to the relevant file or files. A child <area> element can point to part of a <file> that manifests a division, while the <par> and <seq> elements can point to multiple files or parts of files that together manifest a division. More than one <fptr> element can be associated with a <div> element. Typically sibling <fptr> elements represent alternative versions, or manifestations, of the same content

attributes

ID: xsd:ID   optional  
ID (ID/O): This attribute uniquely identifies the element within the METS document, and would allow the element to be referenced unambiguously from another element or document via an IDREF or an XPTR. For more information on using ID attributes for internal and external linking see Chapter 4 of the METS Primer.
FILEID: xsd:IDREF   optional  
FILEID (IDREF/O): An optional attribute that provides the XML ID identifying the <file> element that links to and/or contains the digital content represented by the <fptr>. A <fptr> element should only have a FILEID attribute value if it does not have a child <area>, <par> or <seq> element. If it has a child element, then the responsibility for pointing to the relevant content falls to this child element or its descendants.
CONTENTIDS: URIs   optional  
CONTENTIDS (URI/O): Content IDs for the content represented by the <fptr> (equivalent to DIDL DII or Digital Item Identifier, a unique external ID).

Element <par>

type="parType" minOccurs="0"
The <par> or parallel files element aggregates pointers to files, parts of files, and/or sequences of files or parts of files that must be played or displayed simultaneously to manifest a block of digital content represented by an <fptr> element. This might be the case, for example, with multi-media content, where a still image might have an accompanying audio track that comments on the still image. In this case, a <par> element would aggregate two <area> elements, one of which pointed to the image file and one of which pointed to the audio file that must be played in conjunction with the image. The <area> element associated with the image could be further qualified with SHAPE and COORDS attributes if only a portion of the image file was pertinent and the <area> element associated with the audio file could be further qualified with BETYPE, BEGIN, EXTTYPE, and EXTENT attributes if only a portion of the associated audio file should be played in conjunction with the image.

Element <seq>

type="seqType" minOccurs="0"
The sequence of files element <seq> aggregates pointers to files, parts of files and/or parallel sets of files or parts of files that must be played or displayed sequentially to manifest a block of digital content. This might be the case, for example, if the parent <div> element represented a logical division, such as a diary entry, that spanned multiple pages of a diary and, hence, multiple page image files. In this case, a <seq> element would aggregate multiple, sequentially arranged <area> elements, each of which pointed to one of the image files that must be presented sequentially to manifest the entire diary entry. If the diary entry started in the middle of a page, then the first <area> element (representing the page on which the diary entry starts) might be further qualified, via its SHAPE and COORDS attributes, to specify the specific, pertinent area of the associated image file.

Element <area>

type="areaType" minOccurs="0"
The area element <area> typically points to content consisting of just a portion or area of a file represented by a <file> element in the <fileSec>. In some contexts, however, the <area> element can also point to content represented by an integral file. A single <area> element would appear as the direct child of a <fptr> element when only a portion of a <file>, rather than an integral <file>, manifested the digital content represented by the <fptr>. Multiple <area> elements would appear as the direct children of a <par> element or a <seq> element when multiple files or parts of files manifested the digital content represented by an <fptr> element. When used in the context of a <par> or <seq> element an <area> element can point either to an integral file or to a segment of a file as necessary.

ID (ID/O): This attribute uniquely identifies the element within the METS document, and would allow the element to be referenced unambiguously from another element or document via an IDREF or an XPTR. For more information on using ID attributes for internal and external linking see Chapter 4 of the METS Primer.
FILEID: xsd:IDREF   required  
FILEID (IDREF/R): An attribute which provides the XML ID value that identifies the <file> element in the <fileSec> that then points to and/or contains the digital content represented by the <area> element. It must contain an ID value represented in an ID attribute associated with a <file> element in the <fileSec> element in the same METS document.
SHAPE:   optional   | RECT | CIRCLE | POLY
SHAPE (string/O): An attribute that can be used as in HTML to define the shape of the relevant area within the content file pointed to by the <area> element. Typically this would be used with image content (still image or video frame) when only a portion of an integal image map pertains. If SHAPE is specified then COORDS must also be present. SHAPE should be used in conjunction with COORDS in the manner defined for the shape and coords attributes on an HTML4 <area> element. SHAPE must contain one of the following values: RECT CIRCLE POLY
COORDS: xsd:string   optional  
COORDS (string/O): Specifies the coordinates in an image map for the shape of the pertinent area as specified in the SHAPE attribute. While technically optional, SHAPE and COORDS must both appear together to define the relevant area of image content. COORDS should be used in conjunction with SHAPE in the manner defined for the COORDs and SHAPE attributes on an HTML4 <area> element. COORDS must be a comma delimited string of integer value pairs representing coordinates (plus radius in the case of CIRCLE) within an image map. Number of coordinates pairs depends on shape: RECT: x1, y1, x2, y2; CIRC: x1, y1; POLY: x1, y1, x2, y2, x3, y3 . . .
BEGIN: xsd:string   optional  
BEGIN (string/O): An attribute that specifies the point in the content file where the relevant section of content begins. It can be used in conjunction with either the END attribute or the EXTENT attribute as a means of defining the relevant portion of the referenced file precisely. It can only be interpreted meaningfully in conjunction with the BETYPE or EXTTYPE, which specify the kind of beginning/ending point values or beginning/extent values that are being used. The BEGIN attribute can be used with or without a companion END or EXTENT element. In this case, the end of the content file is assumed to be the end point.
END: xsd:string   optional  
END (string/O): An attribute that specifies the point in the content file where the relevant section of content ends. It can only be interpreted meaningfully in conjunction with the BETYPE, which specifies the kind of ending point values being used. Typically the END attribute would only appear in conjunction with a BEGIN element.

BETYPE: Begin/End Type. BETYPE (string/O): An attribute that specifies the kind of BEGIN and/or END values that are being used. For example, if BYTE is specified, then the BEGIN and END point values represent the byte offsets into a file. If IDREF is specified, then the BEGIN element specifies the ID value that identifies the element in a structured text file where the relevant section of the file begins; and the END value (if present) would specify the ID value that identifies the element with which the relevant section of the file ends. Must be one of the following values: BYTE IDREF SMIL MIDI SMPTE-25 SMPTE-24 SMPTE-DF30 SMPTE-NDF30 SMPTE-DF29.97 SMPTE-NDF29.97 TIME TCF XPTR
EXTENT: xsd:string   optional  
EXTENT (string/O): An attribute that specifies the extent of the relevant section of the content file. Can only be interpreted meaningfully in conjunction with the EXTTYPE which specifies the kind of value that is being used. Typically the EXTENT attribute would only appear in conjunction with a BEGIN element and would not be used if the BEGIN point represents an IDREF.
EXTTYPE:   optional   | BYTE | SMIL | MIDI | SMPTE-25 | SMPTE-24 | SMPTE-DF30 | SMPTE-NDF30 | SMPTE-DF29.97 | SMPTE-NDF29.97 | TIME | TCF
EXTTYPE (string/O): An attribute that specifies the kind of EXTENT values that are being used. For example if BYTE is specified then EXTENT would represent a byte count. If TIME is specified the EXTENT would represent a duration of time. EXTTYPE must be one of the following values: BYTE SMIL MIDI SMPTE-25 SMPTE-24 SMPTE-DF30 SMPTE-NDF30 SMPTE-DF29.97 SMPTE-NDF29.97 TIME TCF.
ADMID: xsd:IDREFS   optional  
ADMID (IDREFS/O): Contains the ID attribute values identifying the <rightsMD>, <sourceMD>, <techMD> and/or <digiprovMD> elements within the <amdSec> of the METS document that contain or link to administrative metadata pertaining to the content represented by the <area> element. Typically the <area> ADMID attribute would be used to identify the <rightsMD> element or elements that pertain to the <area>, but it could be used anytime there was a need to link an <area> with pertinent administrative metadata. For more information on using METS IDREFS and IDREF type attributes for internal linking, see Chapter 4 of the METS Primer

ID (ID/O): This attribute uniquely identifies the element within the METS document, and would allow the element to be referenced unambiguously from another element or document via an IDREF or an XPTR. For more information on using ID attributes for internal and external linking see Chapter 4 of the METS Primer.
ORDER: xsd:integer   optional  
ORDER (integer/O): A representation of the div's order among its siblings (e.g., its absolute, numeric sequence). For an example, and clarification of the distinction between ORDER and ORDERLABEL, see the description of the ORDERLABEL attribute.
ORDERLABEL: xsd:string   optional  
ORDERLABEL (string/O): A representation of the div's order among its siblings (e.g., “xii”), or of any non-integer native numbering system. It is presumed that this value will still be machine actionable (e.g., it would support ‘go to page ___’ function), and it should not be used as a replacement/substitute for the LABEL attribute. To understand the differences between ORDER, ORDERLABEL and LABEL, imagine a text with 10 roman numbered pages followed by 10 arabic numbered pages. Page iii would have an ORDER of “3”, an ORDERLABEL of “iii” and a LABEL of “Page iii”, while page 3 would have an ORDER of “13”, an ORDERLABEL of “3” and a LABEL of “Page 3”.
LABEL: xsd:string   optional  
LABEL (string/O): An attribute used, for example, to identify a <div> to an end user viewing the document. Thus a hierarchical arrangement of the <div> LABEL values could provide a table of contents to the digital content represented by a METS document and facilitate the users’ navigation of the digital object. Note that a <div> LABEL should be specific to its level in the structural map. In the case of a book with chapters, the book <div> LABEL should have the book title and the chapter <div>; LABELs should have the individual chapter titles, rather than having the chapter <div> LABELs combine both book title and chapter title . For further of the distinction between LABEL and ORDERLABEL see the description of the ORDERLABEL attribute.
DMDID: xsd:IDREFS   optional  
DMDID (IDREFS/O): Contains the ID attribute values identifying the <dmdSec>, elements in the METS document that contain or link to descriptive metadata pertaining to the structural division represented by the current <div> element.

Element <smLinkGrp>

The structMap link group element <smLinkGrp> provides an implementation of xlink:extendLink, and provides xlink compliant mechanisms for establishing xlink:arcLink type links between 2 or more <div> elements in <structMap> element(s) occurring within the same METS document or different METS documents. The smLinkGrp could be used as an alternative to the <smLink> element to establish a one-to-one link between <div> elements in the same METS document in a fully xlink compliant manner. However, it can also be used to establish one-to-many or many-to-many links between <div> elements. For example, if a METS document contains two <structMap> elements, one of which represents a purely logical structure and one of which represents a purely physical structure, the <smLinkGrp> element would provide a means of mapping a <div> representing a logical entity (for example, a newspaper article) with multiple <div> elements in the physical <structMap> representing the physical areas that together comprise the logical entity (for example, the <div> elements representing the page areas that together comprise the newspaper article).

Element <smLocatorLink>

minOccurs="2" maxOccurs="unbounded"
The structMap locator link element <smLocatorLink> is of xlink:type "locator". It provides a means of identifying a <div> element that will participate in one or more of the links specified by means of <smArcLink> elements within the same <smLinkGrp>. The participating <div> element that is represented by the <smLocatorLink> is identified by means of a URI in the associate xlink:href attribute. The lowest level of this xlink:href URI value should be a fragment identifier that references the ID value that identifies the relevant <div> element. For example, "xlink:href='#div20'" where "div20" is the ID value that identifies the pertinent <div> in the current METS document. Although not required by the xlink specification, an <smLocatorLink> element will typically include an xlink:label attribute in this context, as the <smArcLink> elements will reference these labels to establish the from and to sides of each arc link.

divType: Complex Type for Divisions The METS standard represents a document structurally as a series of nested div elements, that is, as a hierarchy (e.g., a book, which is composed of chapters, which are composed of subchapters, which are composed of text). Every div node in the structural map hierarchy may be connected (via subsidiary mptr or fptr elements) to content files which represent that div's portion of the whole document. SPECIAL NOTE REGARDING DIV ATTRIBUTE VALUES: to clarify the differences between the ORDER, ORDERLABEL, and LABEL attributes for the <div> element, imagine a text with 10 roman numbered pages followed by 10 arabic numbered pages. Page iii would have an ORDER of "3", an ORDERLABEL of "iii" and a LABEL of "Page iii", while page 3 would have an ORDER of "13", an ORDERLABEL of "3" and a LABEL of "Page 3".

attributes

ID: xsd:ID   optional  
ID (ID/O): This attribute uniquely identifies the element within the METS document, and would allow the element to be referenced unambiguously from another element or document via an IDREF or an XPTR. For more information on using ID attributes for internal and external linking see Chapter 4 of the METS Primer.
ORDER: xsd:integer   optional  
ORDER (integer/O): A representation of the div's order among its siblings (e.g., its absolute, numeric sequence). For an example, and clarification of the distinction between ORDER and ORDERLABEL, see the description of the ORDERLABEL attribute.
ORDERLABEL: xsd:string   optional  
ORDERLABEL (string/O): A representation of the div's order among its siblings (e.g., “xii”), or of any non-integer native numbering system. It is presumed that this value will still be machine actionable (e.g., it would support ‘go to page ___’ function), and it should not be used as a replacement/substitute for the LABEL attribute. To understand the differences between ORDER, ORDERLABEL and LABEL, imagine a text with 10 roman numbered pages followed by 10 arabic numbered pages. Page iii would have an ORDER of “3”, an ORDERLABEL of “iii” and a LABEL of “Page iii”, while page 3 would have an ORDER of “13”, an ORDERLABEL of “3” and a LABEL of “Page 3”.
LABEL: xsd:string   optional  
LABEL (string/O): An attribute used, for example, to identify a <div> to an end user viewing the document. Thus a hierarchical arrangement of the <div> LABEL values could provide a table of contents to the digital content represented by a METS document and facilitate the users’ navigation of the digital object. Note that a <div> LABEL should be specific to its level in the structural map. In the case of a book with chapters, the book <div> LABEL should have the book title and the chapter <div>; LABELs should have the individual chapter titles, rather than having the chapter <div> LABELs combine both book title and chapter title . For further of the distinction between LABEL and ORDERLABEL see the description of the ORDERLABEL attribute.
DMDID: xsd:IDREFS   optional  
DMDID (IDREFS/O): Contains the ID attribute values identifying the <dmdSec>, elements in the METS document that contain or link to descriptive metadata pertaining to the structural division represented by the current <div> element. For more information on using METS IDREFS and IDREF type attributes for internal linking, see Chapter 4 of the METS Primer.
ADMID: xsd:IDREFS   optional  
ADMID (IDREFS/O): Contains the ID attribute values identifying the <rightsMD>, <sourceMD>, <techMD> and/or <digiprovMD> elements within the <amdSec> of the METS document that contain or link to administrative metadata pertaining to the structural division represented by the <div> element. Typically the <div> ADMID attribute would be used to identify the <rightsMD> element or elements that pertain to the <div>, but it could be used anytime there was a need to link a <div> with pertinent administrative metadata. For more information on using METS IDREFS and IDREF type attributes for internal linking, see Chapter 4 of the METS Primer.
TYPE: xsd:string   optional  
TYPE (string/O): An attribute that specifies the type of structural division that the <div> element represents. Possible <div> TYPE attribute values include: chapter, article, page, track, segment, section etc. METS places no constraints on the possible TYPE values. Suggestions for controlled vocabularies for TYPE may be found on the METS website.
CONTENTIDS: URIs   optional  
CONTENTIDS (URI/O): Content IDs for the content represented by the <div> (equivalent to DIDL DII or Digital Item Identifier, a unique external ID).
: xlink:label    
xlink:label - an xlink label to be referred to by an smLink element

Complex type areaType

elements of this type | <area> | <area> | <area>
areaType: Complex Type for Area Linking The area element provides for more sophisticated linking between a div element and content files representing that div, be they text, image, audio, or video files. An area element can link a div to a point within a file, to a one-dimension segment of a file (e.g., text segment, image line, audio/video clip), or a two-dimensional section of a file (e.g, subsection of an image, or a subsection of the video display of a video file. The area element has no content; all information is recorded within its various attributes.

attributes

ID: xsd:ID   optional  
ID (ID/O): This attribute uniquely identifies the element within the METS document, and would allow the element to be referenced unambiguously from another element or document via an IDREF or an XPTR. For more information on using ID attributes for internal and external linking see Chapter 4 of the METS Primer.

BEGIN (string/O): An attribute that specifies the point in the content file where the relevant section of content begins. It can be used in conjunction with either the END attribute or the EXTENT attribute as a means of defining the relevant portion of the referenced file precisely. It can only be interpreted meaningfully in conjunction with the BETYPE or EXTTYPE, which specify the kind of beginning/ending point values or beginning/extent values that are being used. The BEGIN attribute can be used with or without a companion END or EXTENT element. In this case, the end of the content file is assumed to be the end point.
END: xsd:string   optional  
END (string/O): An attribute that specifies the point in the content file where the relevant section of content ends. It can only be interpreted meaningfully in conjunction with the BETYPE, which specifies the kind of ending point values being used.

BETYPE: Begin/End Type. BETYPE (string/O): An attribute that specifies the kind of BEGIN and/or END values that are being used. For example, if BYTE is specified, then the BEGIN and END point values represent the byte offsets into a file. If IDREF is specified, then the BEGIN element specifies the ID value that identifies the element in a structured text file where the relevant section of the file begins; and the END value (if present) would specify the ID value that identifies the element with which the relevant section of the file ends. Must be one of the following values: BYTE IDREF SMIL MIDI SMPTE-25 SMPTE-24 SMPTE-DF30 SMPTE-NDF30 SMPTE-DF29.97 SMPTE-NDF29.97 TIME TCF XPTR
EXTENT: xsd:string   optional  
EXTENT (string/O): An attribute that specifies the extent of the relevant section of the content file. Can only be interpreted meaningfully in conjunction with the EXTTYPE which specifies the kind of value that is being used. Typically the EXTENT attribute would only appear in conjunction with a BEGIN element and would not be used if the BEGIN point represents an IDREF.
EXTTYPE:   optional   | BYTE | SMIL | MIDI | SMPTE-25 | SMPTE-24 | SMPTE-DF30 | SMPTE-NDF30 | SMPTE-DF29.97 | SMPTE-NDF29.97 | TIME | TCF
EXTTYPE (string/O): An attribute that specifies the kind of EXTENT values that are being used. For example if BYTE is specified then EXTENT would represent a byte count.

Complex type fileType

elements of this type | <file> | <file>
fileType: Complex Type for Files The file element provides access to content files for a METS object. A file element may contain one or more FLocat elements, which provide pointers to a content file, and/or an FContent element, which wraps an encoded version of the file. Note that ALL FLocat and FContent elements underneath a single file element should identify/contain identical copies of a single file.
may contain | <FLocat> | <FContent> | <stream> | <transformFile> | <file>

attributes

ID: xsd:ID   required  
ID (ID/R): This attribute uniquely identifies the element within the METS document, and would allow the element to be referenced unambiguously from another element or document via an IDREF or an XPTR. Typically, the ID attribute value on a <file> element would be referenced from one or more FILEID attributes (which are of type IDREF) on <fptr>and/or <area> elements within the <structMap>. Such references establish links between structural divisions (<div> elements) and the specific content files or parts of content files that manifest them. For more information on using ID attributes for internal and external linking see Chapter 4 of the METS Primer.
SEQ: xsd:int   optional  
SEQ (integer/O): Indicates the sequence of this <file> relative to the others in its <fileGrp>.
OWNERID: xsd:string   optional  
OWNERID (string/O): A unique identifier assigned to the file by its owner. This may be a URI which differs from the URI used to retrieve the file.
ADMID: xsd:IDREFS   optional  
ADMID (IDREFS/O): Contains the ID attribute values of the <techMD>, <sourceMD>, <rightsMD> and/or <digiprovMD> elements within the <amdSec> of the METS document that contain administrative metadata pertaining to the file.

GROUPID: xsd:string   optional  
GROUPID (string/O): An identifier that establishes a correspondence between this file and files in other file groups. Typically, this will be used to associate a master file in one file group with the derivative files made from it in other file groups.
USE: xsd:string   optional  
USE (string/O): A tagging attribute to indicate the intended use of all copies of the file aggregated by the <file> element (e.g., master, reference, thumbnails for image files). A USE attribute can be expressed at the<fileGrp> level, the <file> level, the <FLocat> level and/or the <FContent> level. A USE attribute value at the <fileGrp> level should pertain to all of the files in the <fileGrp>. A USE attribute at the <file> level should pertain to all copies of the file as represented by subsidiary <FLocat> and/or <FContent> elements. A USE attribute at the <FLocat> or <FContent> level pertains to the particular copy of the file that is either referenced (<FLocat>) or wrapped (<FContent>).
BEGIN: xsd:string   optional  
BEGIN (string/O): An attribute that specifies the point in the parent <file> where the current <file> begins. When used in conjunction with a <file> element, this attribute is only meaningful when this element is nested, and its parent <file> element represents a container file. It can be used in conjunction with the END attribute as a means of defining the location of the current file within its parent file. However, the BEGIN attribute can be used with or without a companion END attribute. When no END attribute is specified, the end of the parent file is assumed also to be the end point of the current file. The BEGIN and END attributes can only be interpreted meaningfully in conjunction with a BETYPE attribute, which specifies the kind of beginning/ending point values that are being used.
END: xsd:string   optional  
END (string/O): An attribute that specifies the point in the parent <file> where the current, nested <file> ends. It can only be interpreted meaningfully in conjunction with the BETYPE, which specifies the kind of ending point values being used. Typically the END attribute would only appear in conjunction with a BEGIN attribute.
BETYPE:   optional   | BYTE
BETYPE: Begin/End Type. BETYPE (string/O): An attribute that specifies the kind of BEGIN and/or END values that are being used. Currently BYTE is the only valid value that can be used in conjunction with nested <file> or <stream> elements.
