I'm looking for examples of large(ish?) spatial metadata systems that

would be great. Note, I'm specifically not looking at metadata tools.
Just projects that tried to implement such a system.
It's not always easy to separate metadata from the catalog systems
that employ the metadata. I think it's safe to say that hundreds of
millions of dollars have been spent worldwide on earth observation
metadata systems.
Here are some pointers and pointers to pointers:

In terms of success, that's a bit trickier... the holy grail of
spatial search has not been found...
