Thanks, Alan.  That's all useful detail to know.  I'm trying to make  
certain they hard code as little as possible regarding how the SPARQL  
queries are constructed and how the URLs are built from the SPARQL  
results, and this info will be very helpful in guiding those tasks.

Regarding mention of this MBAT work in the HCLS SfN abstract, I do  
make just a small mention of it at the end along with other data sets  
and ontologies we plan to bring into play.  I don't know how this  
would impact authorship.  Personally, I don't think it should effect  
authorship of the HCLS abstract now, since Mouse BIRN hasn't anything  
to show on this front yet.  The work so far has been getting the  
coders familiar with Jena and how to post the SPARQL queries and  
parse the results.  They've also done a review of the MBAT code to  
list the impact this work has on the current code base.  On the other  
hand, the MBAT abstract being worked up should definitely include  
you, if they are going to make explicit mention of using this  
mashup.  I don't know how that will play out given the extreme  
abstract length limits and other MBAT priorities.

In the end, a month prior the SfN meeting, they ask you to note other  
abstracts related through direct collaboration to the work reported  
in your abstract,   They use this when they create the abstract  
database for the 30K attendees.  The typical etiquette is to also  
make mention of the related abstracts in your poster; and/or slides,  
so we can certainly cross-ref each other, should this actually be a  
part of the MBAT presentation at SfN - which I'm doing everything I  
can to make happen.

Re: the degree of mis-alignment across ABA "equivalent" sections,  
remember their current registration (spatially aligning each  
individual brain to the underlying Franklin & Paxinos derived C57Bl/ 
6J brain atlas) has an error of between 100 - 300 microns with it  
mostly coming up at the higher end.

When trying to determine which section from brain X is "equivalent"  
to brain Y based on this atlas registration, the errors are roughly  
additive, which under the worse conditions will essentially be ~0.5  
mm.  The bounding box for an adult mouse brain is roughly:
	rostral-to-caudal axis (back to front - from olfactory cortex to the  
start of the spinal cord): ~ 20 mm
	dorsal-to-ventral axis (top to bottom - from the top of the parietal- 
frontal cortex boundary to the bottom of the hypothalamus): ~6 mm
	left-to-right or sagittal axis: ~10mm

So when the error gets up to 0.5 and your essentially trying to  
compare cell-level (~10 micron) visual patterns, things are bound to  
be off significantly.  I don't think this can be remedied much, until  
the ABA registration process resolution improves.  It IS likely to  
improve over the next year by at least a factor or 2 - 3, and since  
the brain to brain comparisons are essentially twice the registration  
error, we should se the brain to brain comparisons improve  
considerably when that happens.  That's all for ABA (and their image  
processing/alignment/registration collaborators) to work out.

Cheers,
Bill
