Dan,
This is a crucial point and I want to make sure I understand what you
are saying. Are you saying:
1) We use http://purl.org/dcmi/terms/ and http://purl.org/dcmi/dcmitype/
as the namespace URIs and in addition -- ie, redundantly -- we archive
snapshots of their contents at uniq'd URIs?
2) The URIs http://purl.org/dcmi/terms/ and
http://purl.org/dcmi/dcmitype/ are actually not okay. Rather, they
should be something like http://purl.org/dcmi/terms/uniqxyz123/ or
http://purl.org/dcmi/terms/2000/06/?
I'd like to understand what it is that worries you about pouring all
the new stuff into a single namespace. Even with the uniq'd model, if
we have (say) twelve uniq'd URIs with a new one every few months, any
one of those twelve namespaces can -- according to the strawman
policies -- grow with additional elements. It's not clear to me why
this scenario is not equally worrisome, even more so.
Point #1 is actually an idea we have discussed for a long time -- some
implementors need to cite stable standards in software contracts. We
had discussed the idea of periodically archiving snapshots (eg, DCMI
terms "as of" January each year) at stable URIs for precisely that
purpose.
We have circled around these issues a few times, historically
speaking. We need closure, but we need to make sure we are doing the
right thing.
Tom
