Possibly
(1) the localtion was incorrect
(2) the mimetype or extension are not correctly reported

You can figure what is going wrong by carefully looking at
(1) external-filter.xml file
(2) output of beagle-extract-content
(3) output of beagle-info --list-filters (or whatever is the right
command to list all the filters)

No. If you want to store your own indexing data, then why would you
need beagle ?

Yes only if you are willing to write C# code. E.g. lot of our image
filters are extended from other simpler image formats by subclassing
from the generic image classes. You can do the same; but there is no
way to do this outside of C#. This is by design.
