[DAS2] DAS/2 writeback

Allen, thanks for getting the start of a writeback server up and
running!

I'm hoping to try writing back annotations later today.  However, I'm
having problems looking at the annotations in the writeback server via
IGB.  It looks to me like the main issue is that
http://das.biopackages.net/das/genome/yeast/S228C-writeback/segment
returns human chromosome ids in the uri attribute of the SEGMENT
element, instead of yeast ids.  When IGB uses this to compose a query
like 

http://das.biopackages.net/das/genome/yeast/S228C-writeback/feature?over
laps=chr1/10:15000;type=SO:centromere
 
it gets back an empty feature list.  But if I manually edit this to
replace "chr1" with "chrI", 

http://das.biopackages.net/das/genome/yeast/S228C-writeback/feature?over
laps=chrI/10:15000;type=SO:centromere

I get back a list of feature that satisfies the query filters.

Any ideas?

	Thanks,
	Gregg
