Search engines on the Web do not sort, they rank (mostly in an odd manner, to me at
least), whereas OPACs sort. Do we want to make an OPAC out of the Web? If yes, we must
try to copy a library catalog entry into DC. If not, maybe we should walk along
different paths.

Yes, that's why DC.Description / abstract would be useful. BTW, I don't think it
matters much whether DC.Creator and/or DC.Contributor would be displayed or solely
DC.Names.

Yes, you're right. But it becomes less important if you can readily link to the
electronic document on the Web (I know this is a limited view, because it leaves out
pots, paintings, vases, sculptures etc., but it relates to library OPACs).

You can still use first names and abbreviations of first names for deduplication.
Maybe you don't need DC.Creator for that. The variety and inconsistency of
manifestions on the Web of the name of a certain person is another problem, where you
probably can't apply library rules either.
