Lidiriel,

I am reasonably supportive of adding capture and exposure of metadata
from PDS, ISIS2 and ISIS3 datasets in some appropriate fashion. I'd
be open to appropriate patches though I'm not inclined to do much more
directly as implementation than I have already done, unless my original
client (USGS) demonstrated an interest.

I believe we do have some support for detached datasets.  Perhaps that
is only in ISIS3?  I would be happy to have detached support also added
in ISIS2.

Best regards,
