Thank you for the links. We eventually wrote our own sparql parser in
pure python for reasons explained at

The result is http://www.logilab.org/project/fyzz that will be
released this week and passes 93% of the W3C's DAWG tests. Code is
already available from the public mercurial repository.

The AST built by fyzz is not complete yet but provides already enough
information to allow querying CubicWeb with Sparql (starting with
version 3.4 to be published this week).

fyzz can be reused independently of CubicWeb.
