1. See the thread that John Miedema started on June 7. 2. I only look at OL data when I need a large set of data for database testing. I recall comparing the JSON data to the RDF back in mid-May, and almost immediately finding incomplete data. Of course, the RDF "template" has been in a state of flux, so I cannot guarantee that what I saw then still exists (although in many cases I suspect it does). As I run across examples I will post references here, to your attention. 3. The OL schema isn't. What is described on the web site is already out-of-date, yet data entered using an older schema persists. My hunch is that if you were to look at the oldest data you would find much data that does not convert to RDF, which is understandable because you have no way of knowing that that data even existed -- yet it does. I'm not inclined to go out of my way to find some of these odd records for you, but if I run across them on my way to doing other things I would be happy to point them out. 4. Compare http://openlibrary.org/books/OL7051625M.rdf to http://openlibrary.org/books/OL7051625M.json. You will note that the JSON record contains references to the source text at Internet Archive, which the RDF does not. It also contains a certain amount of "administratrivia" (revision numbers, creation date, cover ids) that the RDF also does not possess. Perhaps most importantly, the RDF does not contain a reference to the corresponding work record which contains most of the subject headings (but not the Dewey Decimal Number, which I would have assumed would attach to a work and not an edition. Odd.) Remember, the actual data for any edition, work, or author is stored in the JSON record. You cannot hope to look at the web presentation and be assured in any way that you are seeing all the data; you must look at the JSON record itself. _______________________________________________ Ol-tech mailing list Ol-tech@archive.org http://mail.archive.org/cgi-bin/mailman/listinfo/ol-tech To unsubscribe from this mailing list, send email to ol-tech-unsubscr...@archive.org
