[Tracker] Using tracker extractors from other applications

[Nikolaus Rath <Nikolaus rath org>]

Hello,

I would like to use tracker's apparently quite extensive data-extraction
facilities in my own program. It seems that "tracker-extract -f <file>"
provides all the functionality that I want, but I am wondering if there
is a way to avoid having to re-parse output.

Is there a way to talk to tracker-extract via the DBUS API and e.g. tell
it to return just the nie:plainTextContent attribute? Or some secret,
undocumented command line option?

It would also be nice if there would be a way to process multiple files
without having to start a new tracker-extract instance for every file.


Any suggestions?


Thanks,

   -Nikolaus
