---------------------------------------
Ciao Paolo, wasn't me doing the java-rdfa evaluation but a colleague of the
Sindice team.
I just saw the report. It seems there was a wrong management of nested items.
In general, being the RDFa 1.1 specifications still open (draft), we preferred
to write an in house RDFa programmatic parser to:
- keep under control the support of the specification while evolving;
- have the possibility to add non standard features;
- keep under control extraction algorithm performances .
> Add a new extractor for RDFa using java-rdfa

> I wonder if it is possible to add a new RDFa extractor which uses java-rdfa
> [1].
> java-rdfa is (according to its creator, Damian Steer :-)) "the cruftiest RDFa
> parser in the world" (and he is probably right!). java-rdfa is currently
> passing all conformance tests for XHTML, and the HTML 4 and 5 tests with one
> exception [2]. An online service|demo [3] is also available. java-rdfa, as
> far as I understand, is currently licensed with a BSD license. The Maven
> artifacts are available in the Maven central repository [4].
> From my little understanding of Any23, in order to do this one needs to
> implement BlindExtractor (which extends Extractor<URI>) and ContentExtractor
> (which extends Extractor<InputStream>).
