Cornelius, these are great links and I’ll do some reading up.
Perian, some definitely argue that, but there’s a lot of grey area to say the least. Also, if our intention is ultimately to create a context in which libraries, archives, and museums can publish Linked and/or Open Data, we want to be able to convince them to do so in a way that makes sense to them from a policy and strategy perspective, while also providing appropriate tools. We may use SEO arguments, or highlight other advantages to using CC0, and show that using CC-BY-NC-SA is not only inappropriate for metadata (though theoretically it may aid in sharing for some traditional research purposes), but would also eliminate other advantages of sharing metadata in with a more open license.

Just a couple of points to clarify why this is a more complicated that we like:
You’re right that facts are not copyrightable in the U.S., but not all (meta)data is strictly factual. Lots of LAM metadata is copyrighted – for example, archival finding aids and analytics in cataloging records. If intellectual effort went into it, rights accrue.
There are explicit (meta)data rights and database rights in many countries, and ideally we want LAM metadata to be interoperable irrespective of the legal regime it came from.
So I completely agree that CC0 is the best solution for LAM metadata to insure global interoperability and accessibility. But there are institutions who’ve invested a lot in their (meta)data and want credit for it, so CC-BY may be the most realistic suggestion there. And some non-profit organizations also feel very strongly about the NC clause, for better or worse. The-SA clause is the one we really should steer clear of, if we want interoperability (and ODbL has some of the same problems).
