Thanks for your feedback.

No. The links within the data are the ones provided directly in the JSON :
  - link to authors
  - link to languages

I think it could be interesting to try to automatically lookup the editions
with the same title in the data, so as to create links between different
editions of the same book. Is that what you had in mind ?

Of course you are right. Thanks for spotting this, it is fixed and a blank
node is generated as you suggest (without the foaf type and property
however, simply with a rdfs:label).

I was in touch with them a few month ago when I started to think on this.
Integrating this in the OL interface has not been discussed yet, but as I
mentionned I will be pleased to do so and improve it over time (Anand, if
you wish we can discuss this).
