Dear members of the DAWG,

First, I would like to wish you a happy new year 2007.


Over the last few months, we did some investigation on an extension to
SPARQL (i.e., SPARQL + regular expressions in the predicate position of
the graph patterns).

The results are written down in the following paper which we
hope contains some useful results:

We are also interested to provide an implementation to this extension in
Java, so you can find in the following site an applet that, which presents
what we did until now in the implementation and in the experiments of this
experiments, you can test it in the fragement implemented until now:

The work is continue in developing this extension, so feel free to send
any comments if for example there are bugs, etc.


Best regards,
