agreed elsewhere

An example: W3C collects information in RDF about existing translations of
its documents, and uses that to generate a list of translations.

In Sidar, we collect information about translations of other documents as
well. We can merge the two sets of information, using the same tools, to
produce a more complete list. Or we can tell it that we prefer a particular
version of a translation where there are two. (In theory - I need to find
time to install the nice tools that Ivan Herman developed to work with this
info. But that, as they say, is just a matter of doing work :-)

In a similar way, you can use the information provided by the CCF service in
conjunction with local information. You can even publish your local
information (just by making it available on the Web) to allow other people to
merge both sources and perhaps their own as well...

cheers
