The
descriptor relationType identifies 12 ways in which the media item you are cataloguing is related by intellectual content to some other media item. For most information and digital asset management systems, the related item is its own asset and retains its own separate metadata record.
The distinguishing question to ask yourself is,
"Does this related media item share exactly the same intellectual content descriptions and intellectual property terms as the original media item?"
If the answer is "yes," then create a single PBCore metadata record, but repeat the container pbcoreInstantiation to indicate the existence of a different rendition of the same asset (e.g., a QuickTime and a WindowsMedia digital movie file; or a Beta-SP tape and a PDF transcript of the same program).
If the answer is "no," and the two media items are linked to one another, but do not share the same intellectual content and intellectual property descriptions, generate two separate PBCore metadata records. Document that the two media items and their metadata records are related by using the PBCore elements relationType and relationIdentifier.
Once the type of
relationship is identified, then the companion descriptor relationIdentifier is used to provide a name, locator, accession, identification number or ID where
a related item can be obtained or found.
The bond between the media item you are cataloging and its related media item is selected from this list of 12 types:
Has Format: Used to indicate if the media item you are cataloging exists in another format, elsewhere. For example, your media item may be an interview segment, but it exists in another format, such as a documentary. Format, in this context, refers to the intellectual content and not another tape format or different rendition of a digital file. Use the "format" descriptors in the PBCore container pbcoreInstantiation to identify media format variations or renditions, repeating the container multiple times, as needed, within a single metadata record.
Is Format Of: Used to indicate if the media item you are cataloging is a variation on the format of another media item, but with essentially the same intellectual content. Format, in this context, refers to the intellectual content and not another tape format or variation on a digital file. Use the "format" descriptors in the PBCore container pbcoreInstantiation to identify media format variations or renditions, repeating the container multiple times, as needed, within a single metadata record.
Has Part: Used to indicate if the media item you are cataloging has a companion media item that is a subset or smaller part of your item.
Is Part
Of: Used to indicated if the media item you are cataloging is a subset or part of another media item. For example, your program may be part of a larger series.
Has Version: Used to indicate if the media item you are cataloging has a version,
edition,
or adaptation named elsewhere. Version, in this context, refers to the intellectual content and not a variation on tape format or digital file. Use the "format" descriptors in the PBCore container pbcoreInstantiation to identify media format variations or renditions, repeating the container multiple times, as needed.
Is Version
Of: Used to indicate if the media item you are cataloging is a version, edition, or adaptation
of another media item. Changes in version imply substantive
changes
in content rather than differences in format.
References: Used to indicate if the media item you are cataloging
cites or otherwise points to another media item you are referencing.
Is
Referenced
By:
Used to indicate if the media item you are cataloging is referenced, cited, or
otherwise pointed to by
another media item.
Replaces: Used to indicate if the media item you are cataloging supplants,
displaces, or
supersedes another media item.
Is Replaced
By: Used to indicate if the media item you are cataloging is supplanted, displaced, or
superseded by another media item.
Requires: Used to indicate if the media item you are cataloging requires a companion media item to support its function, delivery,
or coherence of content.
Is Required By: Used to indicate if the media item you are cataloging is
required by a companion media item, either physically or
logically.
