MADS 2.1 - XML Format for Authorities Data (September 26, 2016)

MADS is a MARC21-compatible XML format for the type of data carried in the MARC 21 Authority format. An individual MADS description consists of at least one main <authority> element and any number of additional main elements: <authority>, <related>, and/or <variant>. Each of these main elements contains one or more of the following descriptor subelements: <name>, <titleInfo>, <topic>, <temporal>, <genre>, <geographic>, <hierarchicalGeographic>, <occupation>. One or more descriptor subelements may be combined within an <authority> element to control an authoritative heading that consists of multiple parts, for example, name/title headings and subject strings with various components (e.g. <topic> and <geographic>). MADS main elements (containing descriptor subelements) are then supplemented by any number of minor elements.

At a higher level, the <madsCollection> root element is used to contain a group of MADS descriptions, while the <mads> root element is used to contain main and minor elements within an individual MADS description.

This document does not include descriptions of all MADS elements and attributes. Please see Outline of Elements and Attributes in MADS 2.1 for a comprehensive list.

Root Elements

<madsCollection>

The <madsCollection> element contains a group of MADS descriptions.

<mads>

The <mads> element contains an individual MADS description.

Main Elements

<authority>

The <authority> element is a container that includes a standardized "authoritative" form of an agent (person or organization), an event, a title, or a term (topic, genre, geographic). The authority container may only be repeated to give multiple authoritative forms in different languages or scripts

The geographicSubdivision attribute can be used with the <authority> element to indicate whether or not a concept can append a geographic facet, such as the name of a country or other jurisdiction, region, or geographic feature. This information is important to some controlled vocabularies, such as LCSH. For vocabularies to which this does not apply, the attribute would not be used. The geographicSubdivision attribute is comparable to MARC Authority 008/06, and can carry the following values:

none - no geographic facet applies
direct - a geographic facet may be applied without its larger geographic entity
indirect - a geographic facet may be applied with the name of its larger geographic entity
not applicable - a geographic facet is not appropriate

<related>

The <related> element includes a name or term that has some relation to the authoritative form. It is not a variant because it is a legitimate, authoritative heading on its own. These are equivalent to "see also" references in library catalogs. The type attribute designates the type of relationship, using the following values:

earlier - used for the earlier form of a name, especially corporate bodies that have changed name over time.
later - used for the later form of a name, especially corporate bodies that have changed name over time.
parentOrg - this is a name heading that gives the parent organization of a corporate name heading. There can be more than one parent organization reference on a record, as in the case of jointly held corporations.
broader - this type of reference is for subject authorities, and indicates a hierarchical relationship between two headings.
narrower - this related reference also indicates a hierarchical relationship between subject headings. There may be many narrower headings in a record.
equivalent - a heading which is equivalent to one in another catalog or thesaurus
other - used for a variant that does not have a specified related type. This should be used with an unspecified type of relationship or a general see also reference.
otherType - used for any other specified type of variant that is not enumerated in the schema.

<variant>

The <variant> element includes a reference such as a name or term that is not considered the authoritative form. For example, if the person's authoritative name is John J. Jones, but he is sometimes referred to as J.J. Jones, then J.J. Jones can be entered as a name reference under <variant>. In library catalogs, variant headings are only used as "see" references and are not used on the catalog's bibliographic, but lead users to the correct heading. The type attribute designates the type of variant, using the following values:

acronym - an acronym which is considered a variant of the name in <authority>. Used most frequently for corporate names. Corresponds to MARC Authority 4XX $w/0, value "d".
abbreviation - abbreviation generally applies to titles, when an abbreviation may be used for indexing or identification. It does not have an equivalent in the MARC Authority format, but relates to the field 210 in the MARC Bibliographic format.
translation - a variant which is a translation of the authoritative name or title. These are not distuinguished from other references in the MARC Authority record.
expansion - an expanded form of the name in <authority>.
other - a variant that does not have a specified variant type.
otherType - a variant that has any other specified variant type that is not enumerated in the schema.
hidden - used for a variant form that is not displayed (for instance because it is offensive), with the single allowed value "yes". Corresponds to MARC 4XX $w/3 code "a": Reference not displayed.

Descriptor Elements

<name>
Used for personal, corporate, event, conference, or family names corresponding to MARC Bibliographic and Authority fields 100, 110, and 111, respectively.
<titleInfo>

<temporal>
Used for subject authorities, which may be from a variety of thesauri. It includes temporal/chronological subjects, equivalent to MARC Authority field 148, which relates to the 648 field in the MARC Bibliographic format.
<genre>
Used for genre headings, which may be from a variety of thesauri. It includes genre terms, equivalent to MARC Authority field 155, which relates to the 655 field in the MARC Bibliographic format.
<geographic>
Used for the authoritative names of geographic entities. It is equivalent to MARC Authority field 151, which relates to the 651 field in the MARC Bibliographic format.
<hierarchicalGeographic>
Used to provide an authoritative form for hierarchical geographic names. It does not have an equivalent in the MARC Authority format, but relates to the 662 or 752 field in the MARC Bibliographic format.
<occupation>
Used to provide an authoritative form for names of occupations. It does not have an equivalent in the MARC Authority format, but relates to the 656 field in the MARC Bibliographic format.

Other Elements

<personInfo>

The <personInfo> element is a container element that may be included when the MADS authority (or related or variant) includes the <name> element.
