RE: [open-bibliography] MARC Codes for Forms of Musical Composition

All
 
Karen is spot on - this is the content v. carrier issue, difficult to avoid in
Libraryland although things may get better when RDA starts to kick in. RDA
clarifies the issue by applying the RDA/ONIX framework for resource
categorization to create high-level concepts for content and carrier types. An
immediate utility of this approach is that users can more accurately filter
searches by specific aspects of the content and/or carrier of the items in a
library collection, for example content that does not require the visual sense.
The issue became acute in the 1980s as more and more content appeared on digital
carriers. Query: is the ambiguity of the term "book" reflected in some way in
digital libraries?
 
The FRBR WEMI classes are aspects of a whole; a "full" catalogue record will
usually consist of a Work, an Expression, a Manifestation, and an Item. A
significant utility of FRBR is that it gives cataloguers a better context for
their activity, as the WEMI classes and individual properties are assigned to
the four identified user tasks (find, identify, select, acquire/obtain). A
corollary is that FRBR makes it easier to present the metadata in more useful
ways to the user; typically, the user can drill-down from Work (essentially
equivalent to the brief author/title display often seen in library interfaces)
to Expression (content-related stuff like editions, translations) to
Manifestation (carrier-related stuff) to Item (is it on the shelf?) There is
also the potential for more effective metadata management through reduction of
duplication (one Work record can be linked to multiple Expression records, etc.)
and increased sharing of the cataloguing effort (only create a Manifestation if
no-one else has done so, and then link it to an existing Expression)
 
But I see WEMI as an intermediate stage twixt the record and the statement. The
WEMI classes essentially group bibliographic metadata properties at a lower
granularity than the traditional full record, and perhaps the greatest utility
of FRBR will be to break the hegemony of the catalogue record in the cult(ure)
of cataloguing. See my presentation at
http://gordondunsire.com/pubs/pres/EvolCatRec.ppt(also listed on the wiki).
