[DCRM-L] ALA Core SAC Subcommittee on Faceted Vocabularies releases new resource for comment: “Retrospective Implementation of Faceted Vocabularies”

The ALA Core SAC Subcommittee on Faceted Vocabularies (SSFV) is proud to
announce the completion of the first version of a new resource
entitled Retrospective
Implementation of Library of Congress Faceted Vocabularies: Best Practices
for Librarians and Programmers. This resource (several years in the making)
describes a set of best practices for implementers wishing to apply LC
faceted vocabularies--using purpose-built fields in the MARC 21
bibliographic format--retrospectively to library catalogs, utilizing
automated and semi-automated processes. It is also intended to serve as an
ever-growing hub of information for all matters related to retrospective
implementation of LC faceted vocabularies, including efforts undertaken by
specialist communities of practice, library consortia/cooperatives, library
systems vendors, etc. Lastly, it articulates a “roadmap” for ongoing work
by SSFV and allied communities of practice.

This integrating resource is modular in nature and subject to dynamic,
ongoing updates. Early versions of these best practices will be incomplete.
At the time of this initial release, some modules have been developed by
SSFV or other entities, whereas other modules remain to be developed (and
are represented by a placeholder in the summary document). The following
modules are available to implementers now:

   -

   Genre/Form: mapping MARC fixed field codes to 655 and 385 fields
   -

   Genre/Form: mapping LCSH form subdivisions (and select topical
   subdivisions) to 655, 385, 386 fields
   -

   Genre/Form: mapping LCSH music form headings to 655 fields (not SSFV's
   own work, but a brief description of and links to the Music Library
   Association’s work)
   -

   Medium of Performance: mapping LCSH music form headings to 382 fields (not
   SSFV's own work, but a brief description of and links to MLA's work)

Two appendices contain links to resources for current implementation of
faceted vocabularies, and a bibliography of literature on display and
indexing of faceted data, respectively.

SSFV anticipates updating and re-releasing the summary document
periodically. However, the modules themselves are even more dynamic and
subject to frequent updates, particularly as the LC vocabularies continue
to grow and evolve. Implementers are advised to take into account the “last
updated” date on each module when consulting that module; this date may be
later than the “last updated” date on the summary document.

Feedback sought on summary document: this initial release is characterized
as a “draft for public comment.” SSFV strives to present the most
up-to-date information available, and welcomes feedback and the reporting
of errors at any time, for those modules they are responsible for
maintaining. SSFV will review and incorporate community feedback prior to
publishing a more stable version of the summary document. Feedback on
mappings contained within individual modules is also welcome, and will be
reviewed and acted upon on an ongoing basis, both before and after the
publication of the stable summary document.

Some prompt questions for feedback:

   -

   Are there other methodologies for retrospective implementation that we
   have not addressed?
   -

   Are there additional modules not already included in the roadmap that
   SSFV should plan to develop?
   -

   Are there any other high-level considerations we have not taken into
   account?
   -

   Is your organization/community undertaking any substantial retrospective
   implementation endeavors that SSFV should be aware of? Are there “lessons
   learned” or other takeaways from your project that could inform SSFV’s work?
   -

   (Particularly if you have programming/coding/scripting expertise): Are
   you interested in collaborating with SSFV to test any of the mappings we
   have developed thus far?

A link to the summary document is available here:
https://docs.google.com/document/d/1z26hElRDCxXaxum_Or36-Xg5DBNqv2xt0Mfy0sVCKV4/edit?usp=sharing.
Please direct your questions and feedback to this Google document, or
directly to Casey Mullin, SSFV Chair (caseymullin1 at outlook.com).

Feedback will be accepted on an ongoing basis, but responses received by
the end of February 2022 will receive priority consideration for the
purposes of revising the summary document.

Thank you!
