I recently saw a presentation at the NASA 2004 Earth Science
Technology Conference by Rob Raskin (NASA JPL) of "Enabling Semantic
Interoperability for Earth Science Data":
http://www.esto.nasa.gov/conferences/estc2004/papers/a5p1.pdf
which discusses a similar approach and mentions CF.
At the same conference, James Frew (UCSB) mentioned a name scheme he
is advocating in digital library work based on a server/authority/name
triple, that in turn is based on James Kunze's ARK IETF Draft for
persistent naming:
http://www.cdlib.org/inside/diglib/ark/arkspec.pdf
The latter contains discussion of some of the relevant issues, for
example:
Names must be chosen with great care. Poorly chosen and managed
names will devastate any persistence strategy, and they do not
discriminate based on naming scheme. Whether a mistakenly re-
assigned identifier is a URN, DOI, PURL, URL, or ARK, the damage --
failed access -- is not mitigated more in one scheme than in another.
Conversely, properly managed names will go much further towards
safeguarding persistence than any choice of naming scheme or its
underlying protocols.
but I can't say I agree with the specific recommendations, such as
... names that look more or less like numbers avoid common problems
that defeat persistence and international acceptance. The use of
digits is highly recommended, mixed in with non-vowel alphabetic
characters if compact names are desired.
That's more or less the GRIB strategy of using numbers for everything
...
