i don't think this is true. electronic union catalogs such as those
provided by OCLC and RLG pre-date the semantic web by many years, and
though they constitute centrally managed stores of metadata
information, they rely exclusively on metadata from disparate
sources. more recently, OAI repositories do the same thing. this is
well-trodden territory in the library community.

some in the library community have worked on a standard way of
addressing this area under the aegis of the Dublin Core Metadata

DCMI Administrative Metadata Working Group

i don't think the final form of the document (june 2003) is linked to
from there yet, but i've archived a local copy:


also worth looking at in this connection is:
