Has anyone out there used Apache's UIMA (Unstructured Information
Management Architecture) to index documents or in any other way?
What I am interested in is knowing whether any libraries are using this,
and how they are using it.  Seeing any example projects would be great.  I
also want to know how difficult it was to implement, and get a feel for the
quality of the metadata produced.

Are there any library projects which maybe aren't using this, but which are
using coding to index documents and create metadata?
