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? -Wilhelmina Randtke
