Dear IG,

after investigating the currently available
techniques for querying and transforming 
RDF (for example see [1]) I would like to 
propose an alternative approach that is connected
more closely to the XML development. 

Basically I would like to have the counterparts
of XPath,XSLT and XQuery in the RDF world:
RDFPath,RDFT and RQuery. This approach has (in my
opinion) some advantages:

1. benefit from the lessons learned from XML
2. don't reinvent the wheel: copy and paste as long
   as possible, extend if necessary.
3. be in sync with XML development

This approach is feasible because from a *data model*
point of view XML (tree) is a subset of RDF (directed
labelled graph).

I have collected some thoughts and first
proposals at


Don't expect too much! This is work in progress. Everybody
who wants to contribute or offer help is welcome! 

Since I am visiting the USA from March 23 - April 23 I will
start working on the specification of RDFPath in the end
of April, so there is enough time to collect ideas and
suggestions if someone is interested.
