QUESTION: do we force a remapping of external id sequences
into uris/ first? this seems like a bad idea? or rather,
it is actually a good idea, but it will have to be done with
a pattern based redirect instead of an actual materialization
the alternative is to do what ontobee does and pass the external
iri as a query parameter ... hrm tradoffs, well we certainly
can't make a nice /uberon/uris/obo/{UBERON_} folder if we include
the whole uri ... so this seems a reasonable tradeoff
http://purl.obolibrary.org/obo/ can wind up being mapped into
multiple uri spaces ... /obo/uris/obo/ would seem to make more sense
but how to indicate that other organizations/projects map there ...
/uberon/uris/obo/UBERON_ could indicate the latest sequence
ah, and of course in theory this gets us out of the very annoying
situation where /uberon/uris/obo/UBERON_ really IS different than
/doid/uris/obo/UBERON_ for some identifiers (sigh) and if they are
all mapped and masking based on presence then we can detect the issues
HOWEVER how do we enforce that in reality the _mapping_ is all to
/obo/uris/obo/ ??
