Richard,
I appreciate the response, and I know how hard it is to maintain a legacy
project.
My understanding is that if we are going to host the d2rq namespace
officially as http://d2rq.org/terms/d2rq instead of
http://www.wiwiss.fu-berlin.de/suhl/bizer/D2RQ/0.1, then the file located
at http://d2rq.org/terms/d2rq has to be edited to remove all references
(there are two) to http://www.wiwiss.fu-berlin.de/suhl/bizer/D2RQ/0.1, and
replace them with http://d2rq.org/terms/d2rq.
I¹ve attached a copy of http://d2rq.org/terms/d2rq which I believe is
correct (lines 1 and 16 edited to remove references to
http://www.wiwiss.fu-berlin.de/suhl/bizer/D2RQ/0.1). If you can post that
file, we can run tests against it and report back to you.
Thanks,
George
