Yes, that does sound reasonable to me.

There is a broader point too though. I would like to encourage the idea 
that the feature extraction part of the GIFT should be in some way 
pluggable. When adding a collection, the user should be able to specify 
which feature extraction system he/she wants to use, and there could be 
multiple ones shipped with the GIFT, or others could be available from 
third party sites.

I guess that this would mean that (at least) an attribute would have to 
be added to the collection element in the gift-config.mrml file so that 
the system could be aware of whether features are comensurate for 
different collections.

I am fairly sure there was a discussion about this a few years ago, 
either on this list, or via email - I will have a look for it.

This would make it easier for various GIFT users to share their 
specializations of the system (e.g. I have a version that uses 
annotations too, and I know that Henning has done stuff using a greater 
number of greys, more texture orientations, etc.)

Regards,

David
