[DAS2] Sanger/EBI trip report

[Andreas Prlic]

Hi Andrew!

Thanks for the very good summary.

I wanted to comment on the DAS -registry we are having here at
http://das.sanger.ac.uk/registry/

So far there has not been a mechanism how DAS clients can
programmatically discover available DAS sources, that can be
shared between different DAS clients. This registry addresses
that issue (among others).

One thing that was necessary to do for this, was to provide
"coordinate systems", that describe the data that has been
annotated. E.g. Ensembl can project data from different
coordinate systems into one display so it is important to know
what the data is being served in. - also some coordinate
systems are not supported and therefore such DAS sources have
to be ignored.

What I understood from our discussion there is no convention
on globally unique coordinate systems in DAS2 so far, but I think
that would be a nice feature to have.

There is some documentation on the registry available at
http://das.sanger.ac.uk/registry/help_index.jsp

Greetings,
Andreas
