This discussion is like the poster child for why we need to be able to create application profiles -- every list mentioned here has a point of view (MARC:library cataloging; AAT:holdings as objects; ONIX:product catalog). You should be able to cherry pick the terms you want and declare it YOUR list (or the OpenURL list). Of the lists, the ONIX list 7 looks closest to what I think you are needing. Now, it would be great if the elements in ONIX list 7 were in the metadata registry and had URIs for the terms. That way, you could use the ones you want and everyone would know what you were using because it would be clearly identified. kc Jonathan Rochkind wrote: > Thanks, that's interesting too. > > One of the most useful lists I've found is actually in ONIX, Code List 7. > > http://www.editeur.org/codelists.html > > Although Code List 7 actually needs to be supplemented by Code List 78 > if you want full detail.
