I agree with Nick’s recommendation on post-parsing key mapping, and I’d like to
put in a plug for the RecursiveParserWrapper, which may be of use for you.
I’ve been intending to add that to the app commandline and to server…how are
you handling embedded document metadata? Would the wrapper be of any use or do
you not have any embedded docs in your doc set?
I’ve also been meaning to dump counts of metadata keys from the govdocs1
corpus, would that be of any use, or do you already know the keys that you care
about?
Cheers,
Tim

That seems to be the now-obvious solution, thanks for the suggestion.

I've tried a way to add a step late in the pipeline I'm not super familiar with
the Tika codebase so got lost a bit. Any pointers (examples / tutorials) you
could guide me towards? Chapters in the Tika book? I want to explore this if
the server idea doesn't pan out.
