At the time there wasn't enough real world use of SKOS w/ coordination
to warrant cooking something into the SKOS vocabulary itself. However,
as Karen points out there is a real need.
Since the components are controlled:
Teenage girls -- Fiction <http://id.loc.gov/authorities/sh2008112612#concept>
Comic books, strips, etc <http://id.loc.gov/authorities/sh99001401#concept>
it's possible to imagine a vocabulary that would let you do this:
@prefix rdf: <http://www.w3.org/1999/02/22-rdf-syntax-ns#> .
@prefix rda: <http://RDVocab.info/Elements/> .
@prefix dct: <http://purl.org/dc/terms/> .
@prefix lcsh: <http://id.loc.gov/authorities/> .
@prefix skos: <http://www.w3.org/2004/02/skos/core#> .
@prefix ex: <http://example.org/coordination#> .
<http://lccn.heroku.com/36029351#i>
rda:titleProper "Charlotte Temple" ;
dct:subject [
ex:coordinates
<http://id.loc.gov/authorities/sh2008112612#concept>,
<http://id.loc.gov/authorities/sh99001401#concept> ;
skos:prefLabel "Teenage girls--Fiction--Comic books, strips, etc."
] .
This is just a straw-man to demonstrate that there are potential
solutions. I wonder has the time come to put together a SKOS
coordination vocabulary? I recently heard from Antoine Isaac that
several people are considering forming a Libraries and the Semantic
Web Incubator Group, or Interest Group of some kind at the W3C. This
would be a nice piece of functionality for such a group to work on I
think. My only concern is that things at the W3C might not be open
enough to allow participation from folks in libraries -- since most
libraries aren't W3C members. But I imagine there is a way to involve
any interested folks. If you are interested Antoine (cc'ed here) is
the person to get in touch with at this point.
