[DAS2] transitioning from DAS/1 to DAS/2

[Andrew Dalke]

What should we do to make DAS/1 -> DAS/2 transitions easier?

For at least a year I expect there will be both DAS/1 and DAS/2
servers.  We have or will have clients which can handle both
interfaces.

I expect the metadata server should support both server types.
This means it must describe that data source "X" uses interface "A".

I also expect that "A" can be:
   - DAS/1 genomic annotations
   - DAS/1.5 structure annotations
   - DAS/2 genomic annotations
   - DAS/2 protein annotations
   - DAS/2 structure

We've already talked about the need for identifying the different
DAS/2 data sources, based on Andreas Prlic's comments.

But we didn't talk about how to handle DAS/1 data sets in
the metadata server.

At present I don't have even a sketch of an answer.

In theory this registry could be extended to a registery of many
different data sources and API (eg, 'go to this Oracle database,
which uses the biosql schema').  That's well outside the scope of
this question.
