DOI name

1

Specific DOI name allocated to the identified referent.

referentIdentifier(s)

0-n

Other identifier(s) referencing the same referent (examples: ISAN, ISBN, ISRC, ISSN, ISTC, ISNI).

This element contains a type element appropriate to the primaryReferentType. The schema at present recognises a creationIdentifierType and partyIdentifierType, which are open lists1).

referentName(s)

0-n

Name(s) by which the referent is usually known (example: title).

This element contains a type element appropriate to the primaryReferentType. The schema at present recognises a creationNameType and partyNameType, which are open lists1).

This element also contains a language element, for which the allowed value list is the ISO 639-2 code list.

primaryReferentType

1

The primary type of the referent (examples: creation, party, event). This is an open list1).

structuralType

1

The primary structuralType of a referent.

For creations, there are four mutually exclusive creationStructuralTypes (physical, digital, performance, abstraction) that allow classification according to overall form. Where structuralTypes may be contained within one another, the referent's structuralType is defined by the overall form (for example, a CD (physical) may contain files (digital) which contain recordings of performances of songs (abstractions)), and elements of content can be further classified if necessary under referentType.

For parties there are three mutually exclusive partyStructuralTypes (person, animal, organization). These lists are closed2).

mode

0-n

For creations only, the principal sensory mode(s) by which a referent is intended to be perceived (audio, visual, tangible, olfactory, tasteable, none). Mode identifies only the principal intended modes of perception. Most physical resources are perceivable with all five senses, but some of these perceptions may be trivial. For example, a printed book may be touched or smelled, but these are supplementary or incidental to visual mode, the intended function as a content carrier. For a Braille book, however, tangible would be a principal mode. This list is closed2).

character

0-n

For creations only, a fundamental form of communication in which the content of a referent is expressed. There are four values: music, language, image, other. This list is closed2).

referentType

Specification of type(s) of referent for parties: author, composer, book publisher, library, university, financial institution, film studio.

For creations, the abstract nature of the content of a referent, irrespective of its creationStructuralType, is typically described by creationType, which may be extended as needed to include format and genre elements (examples: audio file, scientific journal, musical composition, dataset, serial article, eBook, PDF).

For parties, referentType is a role with which the party is associated and is described by associatedPartyRole (examples: Composer, Author, BookPublisher, JournalPublisher).

This is an open list1).

linkedCreation

0-n

This element contains a creationRoleToCreation element, which is an open list for which new allowed values may be registered.

linkedParty

For parties only. Another party with which a referentParty is associated.

This element contains a partyRoleToParty element, which is an open list1).

principalAgent
