Hello,
I have been notified by Hugh Taylor that LCSH @ zvon.org
(http://zvon.org/lib/lcsh/index.html) contains:
"Cambrian Railways - this subject term was deleted in Sept 2009 (it's
now a name term, and will turn up as and when LC gets round to
releasing its Names file via id.loc.gov).
West Carbery Tramways and Light Railways - this subject term was
deleted in Dec 2009 (it's now a reference on a different name heading,
and the misspelling of "Carberry" has also been corrected)"
I have investigated the XML files and found that the information is
contained in skos:changeNote, which is a suitable SKOS tool to add
such message (one of documentation properties), but for such an
important information it would be very valuable if it was also present
in some more machine friendly way.
Would it be worthwhile to investigate such possibilities or are the
changes to the format rather problematic?
Mila
