This is the sort of issue I am trying to get my head around in relation to my particular area of interest: the museums community. I'm trying to form a view on what museum collections information systems could contribute to the Linked Data effort, and my current thinking is "objects in a historical context". I've had a go at putting up one museum's 60,000 objects as not-very-linked-data, see e.g.: http://collections.wordsworth.org.uk/object/rdf/GRMDC.C104.15 which gives an idea of the sort of information that might be present (for Fine Art materials, anyway). One no-brainer is that this sort of exercise allows museums to assign persistent URIs to their own objects, as I have done here. Another obvious conclusion is that the museum community ought to get its act together and agree on a vocabulary/ontology for the predicates in these object descriptions. I'm currently using DBpedia properties, but there are frameworks like the CIDOC Conceptual Reference Model which might serve better. After that it all gets a bit hazy. I've made a hook-up to Geonames if there is an "exact match" on the place name in the data (which is done dynamically in the XSLT transform which generates the RDF). I could, in principle, go to resources like the Getty AAT for techniques, etc., as and when it has an API which allows me to query it and get XML back. However, my biggest query is about people - in a museum/historical context, you're talking about all the people who ever lived, whether famous or not. I could invent URIs for each person mentioned in the Wordsworth Trust data, and publish those, but then they would be locked into a single silo with no prospect of interoperability with any other museum's personal data. Mapping names across thousands of museum triple stores is not a scalable option. So ... is there a case for "deadpeople.org", a site which does for historical people what Geonames does for place names? ("dead" = "no data protection issues": I'm not just being macabre.) The site should expect a constant flood of new people (and should issue a unique URI for each as it creates the central record), but should also allow queries against existing entries, so that the matching process can happen on a case-by-case basis in a central place, rather than being done after the event.
