Hi Pascal, That is great! Linking to Open Library makes Open Library more visible in the Linked Data world, I guess.
I read your blog post, and would like to raise a couple of questions with you. First of all: where are the links? I see no link to the OL website (or a Work URI) on the page that is said to be an example... Did you only link to Works, or to Editions too? ISBNs are associated with Editions, so I'd expect that would be the first stop. Editions contain TOCs too, Works don't. Or are there too many Editions with the same ISBN? And regarding your remarkable example: that German version of Lord of the Rings should not be linked to a German work, but to The One Work called "The Lord of the Rings" (I consider the separate publications of the three parts one work each). The German work is a duplicate. I recently published [1] a list of works that appear to be duplicates (based on title, subtitle and author) which unfortunately showed that a lot of cleaning up of edition-less works and duplicate works has to be done. That brings up another question: will you do the linking process again in the future? I imagine that eventually many works (and authors, and probably editions too) will be merged so that the Work URI you get back (in the Edition data) when you lookup the same ISBN again may change in the future. I don't think it will be a problem to have old URIs in your data, as they will redirect to the new URI(s) when you look them up. However, if you leave the old URIs in your dataset, you don't know for sure how many distinct works are linked. And since Open Library data changes regularly anyway, I don't suppose this was an one-time only experiment? Is the code you used to convert the datadump to RDF available online (and is it Free software)? Since my proposed changes to OL's "native" RDF output [2] haven't been accepted yet, perhaps other approaches can be promoted somehow. Talis's approach works well, but I'm interested to see others too.
