Why invent a new element for title (etc.) rather than using Dublin Core?
Wouldn't it have been easier to do this building from SWAP?

251 elements!! Man... At least they're not just numbers, but ... do you
expect anyone to actually use it?


There are very few elements in RDA that have a real DC equivalent (although you'll find somewhere in the RDA documentation an RDA-to-DC crosswalk). Title may be the only one that could use the DC term, but I also have to confess that "title" as an element is not actually used in RDA -- only specific types of title (title proper, parallel title, etc.). The list we were working from had 'headers' like title, followed by specific elements, and we haven't yet decided if these headers become classes. So the element title is an anomaly, and there are a small number of others in the list that will require more study. That said, if the RDA 'title' has sub-elements for types of title, then I don't think we can use dcterms:title as it is defined.See the note under

251 elements -- well, have you looked at RDA? That's why we want to develop application profiles -- so that people can select only the elements they actually need. RDA attempts to cover all possible cataloging situations (as did AACR) so it's full of instructions that will be used only by very specialized libraries. (Note that MARC has 175 fields and 1711 subfields -- and many of those subfields are what we would call 'elements'. RDA does not cover everything that is in MARC, so an actually data format that includes RDA will need many more than the RDA 251.)
