JSR 175 (???) is doing them and it is led by a fairly smart guy so hopefully
they will be kool. I hope they don't try to over define it though as that
will screw it up but if they don't it could be sweet. JSR 175 is why I have
been so insistent on keeping only type information in the
BlockInfo/ComponentInfo as it will give us a clean migration path to JDK1.5s
features.

No idea. Parts of it definetly could be. The end client is telstra (a local
telco) who does not give a doodie about the code IP and my indirect employer
already intends to keep 90% of the infrastructure code as part of the deal.
So it may be possible. Though it is rather ugly code ;)
If there was an opensource implementation of the MetaData JSR then I would
definetly do it properly. I have already rewritten the basic plumbing about 5
times because it is easier to do that than do it properly. Going via
something like the MetaData API would make it worth the effort.
Anyone familiar with any object metadata frameworks in opensource land?
