Hi Ray,

please excuse if this is dumb question, but I am new to the RDF topic. What
kind is the piece of software you called "Sergey's parser"? Is this public
domain/open source software? Where can I find it? I once planned to write my
own XML -> RDF model -> XML software, but tracking the additionally generated
statements (reified statements, bags, aboutEach, aboutEachPrefix), so that no
extra/unneccessary statements are produced for them in the output phase, was a
hurdle too high for my first attempt.
