1.Is the demodataone.xml tree actually supposed to work on the OA for PSF?
I tried and it doesn't work. Is there a xml tree available to check OA
query response.

I want to know what's going on at OA?

2. Any notes on the correct way to query the OA? Syntax?? I got the
following error when I queried the example query given in IRIS paper.........

command > query 128.2.70.1
//usRegion[@id='NE']/state[@id='PA']/county[@id=['Allegheny'/city[@id='Pittsburgh']/neighborhood[@id='Oakland']/block/parkingSpace[available='yes']
//usRegion[@id='NE']/state[@id='PA']/county[@id=['Allegheny'/city[@id='Pittsburgh']/neighborhood[@id='Oakland']/block/parkingSpace[available='yes']
