When you say that the meta-data for the artifacts are stored in the
workspace, I assume that you mean that they're stored in the
workspace's metadata (the .metadata folder). Is that correct? And
what's the reason for storing the meta-data in the workspace and not
with the artifacts?
I know that Ivy (http://www.jayasoft.org/ivy) will download required
artifacts into a cache. This cache is a folder (.ivy-cache) in the
user's home directory. Meta-data about the artifacts are also stored
in this cache.

I know that the EMF JET engine (see http://tinyurl.com/c978m) also
stores derived "intermediate" data in the workspace. It does this in a
project called ".JETEmitters". A leading dot is probably a good way to
avoid collision. I think that "Buckminster" should also be part of the
directory name.
