Four questions spring to mind:
* How stable is the nom.tam.fits library? Lots of changes at the moment,
* Is the library already in maven central?
* How complicated is the parser? Is a fairly simple one (basically call
the library, then process the output into Tika structures/formats) or
does it do a large amount of work?
* Are there unit tests?
This is great and I'm totally willing to work with you to shepherd this
in. The first step would be to create a JIRA issue for your parser, and
then to submit a patch to incorporate it into the tika-parsers module. Of
course, you can start with changing the namespace to org.apache.* (from
its current edu.anu.* package).
Then, it would be nice to create a unit test for the parser, and include a
sample FITS file that the unit tests can run against. There are a number
of existing examples under test-resources within tika-parsers.
