This gives me the following result:

So it seems that I still have to parse the entire string. Is there a way
to get the data in more structured form?

 We have code in python doing that for our extraction test cases. Check the class ExtractorHelper in:

http://git.gnome.org/browse/tracker/tree/tests/functional-tests/common/utils/helpers.py

  Basically:

extractor = ExtractorHelper ()

results = extractor.get_metadata (filename)

results is a dictionary with property as key, and a list of values as value. There are few tricks in the translation property->key (because of anonymous nodes)... but i think that with some prints you can figure out how it works.

In our tests we don't specify the mimetype and they work fine.

Hope this helps.

Also, with a plain text document

   tracker.GetMetadata('file:///home/nikratio/misc/Victoria.tex', 'text/plain')

I do not get any contents:

(dbus.String(u''), dbus.String(u' a nfo:PlainTextDocument .\n'))

Am I doing something wrong?


And finally, is there a way to omit the mime type and have tracker
determine it automatically?

Thanks!
