----------------------------------------

I tried Your latest patch however after compiling it doesn't include resources (./contrib/uima/src/resources/*)
to the compiled project. So posting fails :

Thanks for the effort. Great project!

> Provide components to enable Apache UIMA automatic metadata extraction to be exploited
when indexing documents.
> The purpose of this is to get unstructured information "inside" a document and create
structured metadata (as fields) to enrich each document.
> Basically this can be done with a custom UpdateRequestProcessor which triggers UIMA while
indexing documents.
> The basic UIMA implementation of UpdateRequestProcessor extracts sentences (with a tokenizer
and an hidden Markov model tagger), named entities, language, suggested category, keywords
and concepts (exploiting external services from OpenCalais and AlchemyAPI). Such an implementation
can be easily extended adding or selecting different UIMA analysis engines, both from UIMA
repositories on the web or creating new ones from scratch.
