In principle, it is not very tied to DNA.

The main issue with, say, putting up a swiss-prot DAS
server is that DAS would tend to publish every
sequence ID. For genomes this is not a problem (one
per chromosome, or perhaps each large bit of
assembly). For swiss-prot, you will flood clients with
IDs. On the other hand, if you don't publish these IDs
as top-level entry points, there is no DAS way to
discover what IDs are present in a server. Of course,
if you want to provide annotation for a small number
of proteins (say less than a 1000) then this is not a
So - is there an official plan for dealing with
