[bioontology-support] MedDRA URL namespace - MDR or MEDDRA?

The current SPARQL endpoint will not be updated. The new endpoint, when it
becomes available, will use the newer purls, as will with rest of the
system. Note that currently many of the purls in bioportal are not
working. We are working on this problem but it will be next week before it
is resolved. The MedDRA one in your message has been fixed manually but
there are many others that do not work.

So will the reindexing include updating the triple store?  I was hoping to
use the SPARQL endpoint as my definitive source but that currently uses
MDR URLs. Seems like a tricky change since that will break everyone's
SPARQL queries.

Does that also mean the MEDDRA URLs will resolve at some point?
