RE: [Obo-relations] FuGE, Ontologies, NINDS Microarray, GENSAT, ABA, and AD

hi kai,

> I think these are related subjects

well, as we've seen, everything is related to everything else, but,
specifically, there's obviously the need for people to be able to not
only compare microarray experiments for similarities but all types of
system biology experiments, one interesting use case (among many) is
comparing proteomic results with gene expression results for the same
set of subjects.

> Before going into further 
> detail about how to convert NINDS microarray data into OWL ...

one item i was unclear on was what the scope of conversion of microarray
data into OWL you have in mind.  my take on this, as i said previously,
is that in MAGE and eventually in MAGEv2, the actual performance of the
microarray experiment and the results are captured in the XML schema
generated from the UML model.  there is also the ability to annotate,
using the ontology package, all the objects in the XML document.  it's
this annotation i believe can be easily translated into RDF or OWL,
based on the early version of the OMG Ontology Metamodel.  the rest of
the document is easily comparable with other documents at the XML or UML
level.

cheers,
michael
