It's certainly been refined, and is now capable of saying more specific things, but as far as I'm aware the "core" of the Dublin Core -- those fifteen elements -- are pretty much as they always were. At least, that's my reading of http://dublincore.org/documents/dces/ (Can someone confirm or deny this?) The biggest gap between vanilla DC and the Cross-Domain attribute set was originally Ralph's aggregation of DC's Creator, Editor and Publisher elements into a single "Name" access point (which is why the set contains only thirteen elements rather than fifteen.) Seems to me that this is still the only substantial discrepancy. We should -- perhaps -- think about fixing that, and making the cross-domain set a Dublin Core set, done and dusted. That would certainly make it easier for non-Z39.50 people to understand what we're doing. BTW., the cross-domain attribute set definition at http://staff.oclc.org/~levan/docs/crossdomainattributeset.html includes a link to a commentery on the set, which makes interesting background reading (and is short enough to read in five minutes!) The link's broken, though -- the correct URL for the commentary is http://staff.oclc.org/~levan/docs/crossdomainattributesetcommentary.html _/|_ _______________________________________________________________ /o ) \/ Mike Taylor <mike@miketaylor.org.uk> www.miketaylor.org.uk )_v__/\ "If you're not sure what your options are, pop the ball in the net and we'll discuss it later" -- Bob Paisley.
