Hi,
Having loaded the latest LCSH dump into my home-made "triple store", I
was wondering about deconstructing the headings into their component
parts, and making something like a SKOS ontology or Topic Map from them.
Thus, for example, "Arts--Awards--United States" might become:
<lcshConcept>
<id>sh2002000283</id>
<lang>en</lang>
<heading>
<value>Arts</value>
</heading>
<heading>
<value>Awards</value>
</heading>
<heading>
<value>United States</value>
</heading>
</lcshConcept>
and "Compromise (Islamic law)":
<lcshConcept>
<id>sh85029458</id>
<lang>en</lang>
<heading>
<value>Compromise</value>
<scope>Islamic law</scope>
</heading>
</lcshConcept>
Is this a reasonable interpretation of the semantics of "--" and "(...)"
in LCSH? And hasn't someone else already done this sort of exercise -
surely they must have? (My thinking is that LCSH headings are sort of a
post-coordinate system, and the pre-coordinated components of headings
might prove to be interesting and useful on their own account - not
least for indexing Open Library materials.)
