Hi Andreas,

Thanks for the effort and the interesting doc.

It should be noted that the RDF Data Access Working Group has also
analyzed a number of languages not covered in the doc, including Xquery
based approaches. It is particularly relevant since their charter
explicitly references the use of XQuery. Two examples of such XQuery
extensions are TreeHugger and the language used by Network Inference to
query RDF and Owl ontologies.

I would also like to point out that the DAWG working group has not
received your original message; cross-posting to a large number of
different groups is discouraged by the W3C and I think your message was
not delivered because of that.

Cheers

Gary

Subject: A Comparison of RDF Query Languages



Related to the recent work of the RDF Data Access Working Group [1], we
have
compared six proposals for RDF query languages. The report, the use case
data, and the queries are available online [2].

Looking forward to hearing your feedback.
