RE: pre-coordination

Quote:  "Can anyone point me to research or implementations around the
question of subject pre-coordination in a linked data context? It seems to
me that this is still the elephant in the room when it comes to dealing with
LCSH in a meaningful way."

The XG use case 'Component Vocabularies',
http://www.w3.org/2005/Incubator/lld/wiki/Use_Case_Component_Vocabularies,
deals specifically with this; its name (the "component" part) was chosen to
emphasize the pre-coordination aspect.

For example consider the (hypothetical) LCSH subject heading  "Sailboats --
Design and construction". A bibliographic description for a book about
sailboats might cite this subject heading and link to its authority
description in MADS/RDF, which in turn will link to the individual component
subject headings, "sailboats" and "Design and Construction".  

The MADS RDF work, which has been developed over the past year or so,
provides the necessary granularity to understand the components of the
heading; a MADS/RDF ontology is expected to be available for public review
within the next week or two.

Subject: pre-coordination

 From the SKOS Primer:

"Rather than commit to a design pattern that has not been proven useful, the
Semantic Web Deployment Group decided to postpone the issue of coordination,
to allow extension patterns to organically emerge as SKOS is deployed. The
hope is that as successful patterns are established, they can be published
on the Web as an extension vocabulary to SKOS and documented as a W3C Note
or some equivalent."

Have there been any recent developments in this area? Can anyone point me to
research or implementations around the question of subject pre-coordination
in a linked data context? It seems to me that this is still the elephant in
the room when it comes to dealing with LCSH in a meaningful way.

Of particular interest to me is the question of how to express one-to-many
or many-to-many matches between SKOS concepts. So, e.g., mapping between
pre-coordinated LCSH and post-coordinated AAT & TGN:

LCSH topical "gilt furniture" = AAT Activities "gilt" + AAT Objects
"furniture"
LCSH topical "Leatherwork--Alaska" = LCSH topical "Leatherwork" + NAF
"Alaska" = AAT Activities "leatherworking" + TGN "Alaska"

Thanks,

Cory
