title:
Library of Congress METS Profile for Recorded Events [Draft]

abstract:
The Library of Congress Recorded Events METS Profile specifies how METS documents representing recorded events should be encoded. The term "recorded event" includes both audio and video recordings. This profile will typically be used for non-commercial recordings of events such as concerts, lectures, or radio and television broadcasts. A distinctive feature of the profile is that it represents the physical structure of a given audio or video program as a simple sequence of time-based segments. These segments are expressed in the METS structMap section of the METS document. There is no attempt made to express the physical components (e.g. tape, disc, side, track, etc.) of the original carrrier.

metsRootElement:

requirement: @ID="rt01" @RELATEDMAT="ex01"

The METS root element must have an attribute PROFILE="//www.loc.gov/mets/profiles/00000009.xml".

Example 1.

    <mets:mets PROFILE="//www.loc.gov/mets/profiles/00000009.xml">

A document must contain one and only one Descriptive Metadata Section (dmdSec) with a wrapped (mdWrap) MODS bibliographic record. The mods element must have an ID attribute.

Example 2.

If the recorded event contains subparts that are to be described, the MODS element must contain one Related Item (relatedItem) element for each sub-part. An example of a sub-part might be a recorded concert with a relatedItem describing each musical work. Each relatedItem element must have an ID attribute and a type="constituent" attribute.

If a musical work (as is in the previous example) or any other kind of event segment, has logical sub-parts of its own, the logical structure of those sub-parts may in turn be represented with relatedItem type="constituent" child elements. Examples of logical sub-parts are the movements of a musical work, the acts and scenes of a dramatic work, etc. The logical structure of a work (or any other kind of program segment) will thus be represented as a heirarchy of relatedItems type="constituent". All relatedItem type=constituent" elements must be given an ID attribute.

Note also that a recorded event might be subdivided into sub-parts for purely arbitrary reasons (rather than logical sub-parts based on the content of the recorded program). The typical example of this is breaking a long program into shorter segments based on arbitrary time durations. As with logical sub-parts, relatedItems may be used to represent these event segments.

A METS document may optionally contain preservation-related metadata that is expressed using the PREMIS schemas. PREMIS data can be associated with either the entire object (i.e. data that is applicable to all component files), which is, in PREMIS terms, considered to be at the level of the object category "representation", or PREMIS data may associated with individual files. The following brief example shows a possible encoding for the date of a preservation "event" (i.e. the date of digitization) for an audio file. Note that (as of this writing) PREMIS is still very new, and that best practices for its use with METS have not yet emerged.

File Section

The content files referenced by the fptr elements (in the structMap) must point to the appropriate files in the File Section (fileSec). The highest quality or "master" files must be contained in File Group (fileGrp) elements with a USE="MASTER" attribute. File (file) elements must have a MIMETYPE attribute with appropriate value and File Location (FLocat) elements must have a LOCTYPE attribute with appropriate value. The profile makes no further requirements regarding the fileSec element. The example document in Appendix 1 provides a more complete example of Library of Congress practice (see the XML version of this document).

structMap:

requirement: @ID="st01" @RELATEDMAT="ex07"

The physical structure of the recorded event will be represented in the Structure Map (structMap) section of the METS document. The document will have one and only one structMap. The structMap element must contain one and only one top level div TYPE="re:recordedEvent" child element. The top-level div element of the structMap must have a DMDID attribute that points to the mods element.

The div TYPE="re:recordedEvent" element must contain one or more div TYPE="re:segment" elements. The div TYPE="re:segment" elements represent ordered, time-based segments of the recorded program (i.e. the document order of the div TYPE="re:segment" elements must reflect the audio or video program order). A div TYPE="re:segment" element has no furthur semantic meaning. The entire recorded event object will always be expressed as a sequence of one or more segments.

Each div TYPE="re:segment" elements must contain either one div TYPE="re:audio" child element or one div TYPE="re:video" child element.

In the case where there is only one div TYPE="re:segment" element (as in Example 5) the DMDID attribute must also point to the mods element.

In the case where there are more than one div TYPE="re:segment" elements (as in Example 6) the DMDID attributes must must point to the corresponding relatedItem type="constituent" elements in the MODS record. In some cases the relatedItem type="constituent" elements represent only arbitrary segments of the recorded event (perhaps based only on time duration) but where navigation of the segments is desirable. This is the case in the following example.

In other cases, the segments may be associated with the appropriate relatedItem elements where the relatedItems provide a more thorough description of the logical structure (i.e. the program content) of the recorded event. This is the case in the following example. Note that this approach provides a method for correlating the two differing hierarchical representations (logical and physical) of the recorded event object.

A recordedEventObject may also contain text and image content in addition to audio or video content. A text file may exist as a transcription of the audio program content, or may exist as a transcription of text that appears on the original container, or, in any document that is inserted in the container. (These include the kind of documents usually described as "accompanying material", e.g. a concert program, a curator's notes, a recording engineer's notes, etc.). Images may exist as scans of the original container, or as scans of an inserted document.

The profile thus provides for the following possibilities: 1) A text transcription of an entire recordedEvent, 2) A text transcription of an audio or video segment, 3) A text transcription of material from the original container, 4) A text transcription of an inserted document, 5) Images of the container, 6) Images of an inserted document, and 7) An illustrative image. Each of these will be demonstrated in the examples that follow.

requirement: @ID="st05" @RELATEDMAT="ex10"

A text transcription of an entire recordedEvent is expressed as a div TYPE="re:text" element. In this case the div TYPE="re:text" element will occur as a child element of the div TYPE="re:recordedEvent" element as in Example 8.

In some cases it may be desirable to create a single arbitrary image for the purpose of illustration. A typical example of this is using a still image captured from a video program to serve as an illustration when displaying the bibliographic information for the video in question. In this case the div TYPE="re:recordedEvent" element will contain one div TYPE="re:illustration" element which in turn will contain one div TYPE="re:image" element.

Example 16.

    <mets:mets xmlns:re="//www.loc.gov/mets/profiles/recordedEvent" xmlns:rights="//www.loc.gov/rights/" xmlns:lc="//www.loc.gov/mets/profiles" PROFILE="//www.loc.gov/mets/profiles/00000009.xml">

The following example provides an illustration of all the possibilities for building a structMap. Note that the div elements that indicate content type (i.e. div TYPE="re:audio", div TYPE="re:video", div TYPE="re:text", and div TYPE="re:image" are always leaf nodes. These div elements will always contain an fptr child element.
