ANN: Krextor 0.2 (XML --XSLT--> RDF extraction framework)

Dear all,

  only for the second release of Krextor, my XML–XSLT→RDF extraction
framework, I realised that this is probably the most appropriate place to
discuss it.  (If this is not the right place to discuss about GRDDL-related
applications, let me know.)

So let me start with a short introduction to the project:

Krextor (http://kwarc.info/projects/krextor/) is an extensible XSLT-based
framework for extracting RDF from XML, supporting multiple input languages as
well as multiple output RDF notations.  Krextor provides convenience templates
that try to do “the right thing”™ in many common cases, as to reduce the need
for manually writing repetitive code.

Currently not too many input and output formats are actually implemented.
However, Krextor was designed for easy extensibility. The idea is that you
have some semantic web application that works with RDF (e.g. for querying or
reasoning) but that most of your knowledge is hidden in XML markup. Using
Krextor and some suitable ontologies you can then specify a mapping from XML
markup to RDF in terms of these ontologies.  If you want to give it a try …

* for your XML-based language
* for your Microformat or other way of embedding annotations into XML
* for your favourite RDF notation, if your applications don't support RXR.

…, I'd be happy to support you in doing so.

As I'm new to this list, let me shortly introduce myself: I'm a Ph.D. student
working on a semantic wiki for mathematical knowledge
(http://kwarc.info/projects/swim/). Krextor is a spin-off project of this
effort.  Therefore it currently only comes with ready-to-use extraction and
output modules for those XML languages that I'm interested in for my research,
but of course I'm interested in a broader evaluation of the framework, as it
is not restricted to those languages.

I'm not yet that experienced with GRDDL, I only have a basic idea of it, and
in my application I'm not using it because there are only two XML languages
used (OMDoc and OpenMath), and for each of them there is only one RDF
representation of the knowledge that I'm interested in.  But I believe that
due to its modularity Krextor could be interesting for GRDDLing.

Cheers,

Christoph
