I need to be able to take author data from a catalogue record and use it to look up the author on Wikipedia on the fly. So I may have birth date and possibly year of death in addition to (one spelling of) the name, the title of one book the author wrote etc. I know there are various efforts in progress that will improve the current situation, but as things stand at the moment what is the best* way to do this? 1. query wikipedia for as much as possible, parse and select the best fitting result 2. go via dbpedia/freebase and work back from there 3. use VIAF and/or OCLC services 4. Other? (I have no experience of 2-4 yet :-( Thanks Graham * 'best' being constrained by: - need to do this in real-time - need to avoid dependence on services which may be taken away or charged for - being able to justify to librarians as reasonably accurate :-)
