It seems no one complained, so lemme go forward one more step.
The latest commit in SVN now implements the generation of such metadata
about apache2 (this time in turtle format, less verbose than RDF, once
converted from the generated RDF+XML output, in attachment).
I add some comments below for documentation

There are early bits of such navigating / matching bits present, now,
see the comments.
Again, any comments much welcome.
I haven't counted how many triples the whole PTS contains when this is
activated, but... quite a nice contribution to the Linked Open Data
cloud for sure (next steps on my side, with the researcher har on).
