This is very cool - I had a look the other day. Was wondering why some
sources could be attached and some can't....
Best browser experience yet by far I'd say.
No problems about adding CORS support - for the record I'm very happy
to implement new capabilities testing and other suggestions to the
registry from anyone who cares to drop me a line. Especially if it's
going to enhance and promote the use of the registry :)

As some of you already know, I've been experimenting recently with a
web-based DAS client for genomic data. It's still in
a unashamedly prototypical state (in particular, some of the popups
and
configuration stuff is outright clunky, and we know it!), but we're
starting
to find it quite useful, and would be interested to receive more
feedback.
So if you're curious, you can try it here:
http://www.biodalliance.org/human/ncbi36/
It's a fully-fledged DAS/1.53 client (with a few bits of DAS/1.6, and
hopefully rather more coming soon), but has one major caveat: since
it's
pure Javascript code running in your web browser, there are
limitations to
which servers it can connect to. Specifically, it will only work
with DAS
servers that implement the W3C cross-origin resource sharing model
(which
has been discussed on this list before, but drop me a line if you've
got any
questions). What does this mean in practice? If you're adding
datasources
from the registry, things are simple because Dalliance will only
allow you
to add CORS-enabled sources (a huge thanks to Jonathan Warren for
adding
some support for this in the registry). If you run your own DAS
servers and
don't list them in the registry, you'll need to check for CORS
compatibility
yourself. The latest versions of Proserver and Dazzle should both
be okay.
All comments, suggestions, and bug reports are welcome!
Thomas Down.
