Can some of tika-parsers module dependencies be made optional ?

[Sergey Beryozkin]

Hi

A CXF colleague of mine started experimenting with providing a 
light-weight search utility code as part CXF Search API which would use 
a Lucene handler (shipped with CXF for a while) which can translate FIQL 
or ODATA queries into a composite Lucene Query and use it against Tika 
provided metadata and content. The idea is not new, I believe SOLR does 
some very advanced Tika based search. In CXF users would use it as part 
of their regular JAX-RS applications.

The problem seems to be that Tika Parsers module contains many 
dependencies that may not be needed by a specific custom JAX-RS application.

For example, we'd expect a given application dealing with PDF only, or a 
certain set of image formats only, or word docs only, etc.

I'm not sure how many Tika-parsers dependencies are strongly required 
for any Tika application and which can be made optional.

If Tika Parsers does have some possibly optional dependencies then would 
it make sense to make them as such for external Tika consumers having 
not to download all the deps ? It would make a difference IMHO

Thanks, Sergey
