EAD Attributes: General Attributes

ABBRAn abbreviation for a word or phrase that is expressed in an expanded form in the text; used for searching and indexing purposes. Available only in the <expan> element.
ACTUATEsee Linking Attributes
ALIGNsee Tabular Display Attributes
ALTHEADAn alternative short form of the heading element <head> that might be used, for example, to create a running header.
ALTRENDERThe content of the element should be displayed or printed differently than the rendering established in an SGML style sheet for other occurrences of the element. See also RENDER.
AUDIENCEAn attribute that helps control whether the information contained in the element should be available to all viewers or only to repository staff. Available for all elements except line break <lb>. The audience attribute can be set to "external" in <archdesc> to allow access to all the information about the materials being described in the finding aid, but specific elements within <archdesc> can be set to "internal" to reserve that information for repository access only. This feature is intended to assist application software in restricting access to particular information by explicitly coding data that is potentially sensitive or may otherwise have a limited audience. Special software capability may be needed, however, to prevent the export of an element marked "internal" when a whole finding aid is displayed in a networked environment. Values are:
  • external (default value)
  • internal
AUTHFILENUMBERA number that identifies the authority file record for an access term drawn from that authority file. If this attribute is used, the SOURCE attribute should also be used to identify the authority file.
BEHAVIORsee Linking Attributes
CERTAINTYThe level of confidence for the information given in a <date> element. For example:
<date certainty="approximate">ca. 1920</date>

CONTENT-TITLEsee Linking Attributes
COUNTRYCODEA unique code for the country in which the materials being described are held. Codes are to be taken from ISO 3166 Codes for the Representation of Names of Countries, column A2. Available only in <unitid>.
ENCODINGANALOGA field or area in another descriptive encoding system to which an EAD element or attribute is comparable. Mapping elements from one system to another may help build a single user interface that can index comparable information in bibliographic records and finding aid documents. The mapping designations may also help a repository harvest selected data from a finding aid to build a basic catalog record. When possible, subfields as well as fields should be specified, e.g., subfields within MARC fields. If the RELATEDENCODING attribute in <ead>, <eadheader>, or <archdesc> is not used to identify the encoding system from which fields are specified in the ENCODINGANALOG attribute, then include the system designation in ENCODINGANALOG.

INLINEsee Linking Attributes
LABELA display label for an element can be supplied using this attribute when a meaningful label cannot be derived by the style sheet from the element name or when a heading element <head> is not available. This attribute is available in all the elements within <did>.
LANGENCODING Language encoding for EAD instances subscribes to ISO 639-2 Codes for the Representation of Names of Languages, so the LANGENCODING attribute value in <eadheader> should always be "ISO 639-2". This attribute applies to the entire finding aid.
LANGMATERIALThe language of the collection materials described in <archdesc>, <c>, and <c01-12>. The value of the LANGMATERIAL attribute should be set using the three-letter codes for the appropriate language from ISO 639-2 (e.g., "eng" for English). If two or more codes are needed, separate them by a space, e.g.
<archdesc langmaterial="eng fre ger">
LEGALSTATUSThe statutorily-defined status of the materials being described in the encoded finding aid, as, for example, defined by the Public Records Act of 1958 in the United Kingdom. If not "public" or "private," an explanation may be provided in the OTHERLEGALSTATUS attribute. Available only in <archdesc>, <c>, and <c01> through <c12> elements. Values are:
  • public
  • private
  • otherlegalstatus
LEVELThe hierarchical level of the materials being described by the element. This attribute is available only in <archdesc>, where the highest level of material represented in the finding aid must be declared (e.g., collection, fonds, record group), and in <c> and <c01-12> (e.g., subgroup, series, file). If none of the values in the semi-closed list are appropriate, the value "otherlevel" may be chosen and the term specified in the OTHERLEVEL attribute. Values are:
  • collection
  • fonds
  • recordgrp
  • series
  • subgrp
  • subseries
  • file
  • item
  • otherlevel
MOREROWSsee Tabular Display Attributes
NAMEENDsee Tabular Display Attributes
NAMESTsee Tabular Display Attributes
NORMALA consistent form of the content of the following elements can be provided to facilitate retrieval: <corpname>, <date>, <famname>, <function>, <genreform>, <geogname>, <name>, <occupation>, <persname>, <subject>, <title>, and <unitdate>. For example, the normalized form of "LBJ" or "Johnson" would be "Johnson, Lyndon Baines," and the normalized form of March 17, 1998 would be "19980317".
NUMBEREDThe presence or absence of enumerated materials, as in a bibliographic citation. Values are:
  • yes
  • no
ORIENT see Tabular Display Attributes
OTHERLEGALSTATUSThe legal status of the materials being described in the encoded finding aid, other than the "public" or "private" choices from the semi-closed list in the LEGALSTATUS attribute.
OTHERLEVELThe hierarchical level of the materials described in <archdesc>, <c>, and <c01-12> can be specified when the semi-closed list in the LEVEL attribute (e.g., collection, fonds, series, etc.) does not contain an appropriate term.
OTHERSOURCEThe source of the content of the element or rules for creating the controlled vocabulary term can be specified when the name of the appropriate thesaurus, term list, or set of rules is not present in the semi-closed list in the SOURCE attribute.
OTHERTYPEFor some elements the TYPE attribute has a semi-closed list that includes the value of "othertype." If an appropriate term is not found in the semi-closed list, one can be specified in the OTHERTYPE attribute.
PARENTsee Linking Attributes
PGWIDEsee Tabular Display Attributes
PLACEMENTThe location of the information in the <runner> element is displayed in print (foot or head) or as a digital watermark (background). Values are:
  • foot
  • head
  • background
PUBSTATUSThe information given in the <title> may represent a published work, an unpublished work, or the publication status may not be known. Values are:
  • pub
  • unpub
  • unknown-pub
RELATEDENCODINGA descriptive encoding system, such as MARC, ISAD(G), or Dublin Core, to which certain EAD elements can be mapped using the ENCODINGANALOG attribute. RELATEDENCODING is available in <ead>, <eadheader>, and <archdesc>; the <eadheader> elements might be mapped to Dublin Core elements while the body of the finding aid (<archdesc>) might instead be mapped to MARC or ISAD(G).
RENDERThe formatting of the content of an element is controlled for display and print purposes. Available in <emph>, <title>, and <titleproper>. See also ALTRENDER. Values are:
  • bold
  • italic
  • bolditalic

  • altrender
  • quoted
  • smcaps
  • sub
  • super
  • underline
REPOSITORYCODEA unique code in <unitid> indicating the repository responsible for intellectual control of the materials being described. Use the appropriate code from the official list for the country in which the repository is located, e.g., the Library of Congress National Union Catalog repository code or the National Library of Canada code. This attribute would not be used if the institution does not have such a code.
ROLEA contextual role or relationship for the person, family, corporate body, or geographic location within <corpname>, <famname>, <geogname>, <name>, and <persname> elements. In linking elements, information that explains to application software the part that a remote resource plays in a link.

TYPEThe TYPE attribute is available for a number of elements; its characteristics vary depending on the element to which it applies. Some instances of TYPE have closed lists (e.g., <unitdate>), others have semi-closed lists (e.g., <archdesc> and <dsc>), and some permit character data (CDATA) (e.g., <titleproper> and <physloc>). Semi-closed lists contain a value of "othertype," which allows the specification of an appropriate value in the OTHERTYPE attribute. See individual element descriptions for specific values for this attribute.
UNITAny unit of measurement may be expressed in <dimensions>, <extent>, and <physfacet>.
