[DAS2] DAS1 TYPE attribute "category" is what in DAS2?

Hi Andrew,

Currently the DAS/1 types are not used in a consistent way and so far 
have not been used much...
One of the things that is done as part of the BioSapiens project is to 
come up with a more consistent
definition which annotation types to use.

in DAS/1 the annotation types are used to merge features into a single 
track,
therefore I think the das/1 type would be the equivalent to das/2- 
title then.

it think that is correct.

err - which DAS/2 request do you talk about ? still about types?

So far this is not used in a consistent way ... BioSapiens will come up 
with a convention,
but it is still work in progress...
