Mapping of Terms
Different models of the life cycle of content may have important differences, not least in the specific meaning attached to the names of terms they employ. FRBR, indecs and CRM were each informed by different functional requirements, and so evolved different mechanisms for dealing with the issues that seemed most important to them. Each is a particular view on the "universe of discourse" of resources and relationships: there are many valid views. Broadly, they are compatible, and effective integration of metadata from schemes based on them should be achievable, but they must be handled with care. As an example: the terms abstraction, manifestation, item and expression are often used in considering content life cycles (e.g. a sound recording is the expression of a musical work during a recording session at a particular place and time, and is distinct from, say, the master tape made, which is a manifestation). These were dealt with in indecs, but may have slightly different meanings in other schemes. Such an analysis of meaning of a term from a scheme is possible in indecs by mapping the precise definitions into further terms with precise definitions within the indecs Framework (as illustrated in the example table below). indecs and other frameworks based on it continue to be developed and refined through the process of implementation.
Entity | Definition | Relationship | Examples & standard identifiers |
---|---|---|---|
Abstraction | A creation which is a concept |
|
|
Expression | An event which is a creation (may be a performance) |
|
|
Manifestation | An artefact (a creation which is a thing) containing an infixion (or encoding) of an expression (is either physical, e.g., a book, or digital, e.g., an MP3 file) |
|
|
Item | A single instance of an artefact |

Famous quotes containing the word terms:
“We are well advised to keep on nodding terms with the people we used to be, whether we find them attractive company or not. Otherwise they turn up unannounced and surprise us, come hammering on the minds door at 4am of a bad night and demand to know who deserted them, who betrayed them, who is going to make amends. We forget all too soon the things we thought we could never forget.”
—Joan Didion (b. 1934)
