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...
