RE: bams class style model

I think this looks very nice, John.

To my mind, the Class-only model makes much more sense.  None of these entities - brain regions, cells or molecules - are instances.

The relations between these entities are a mix of universal and existential in nature - e.g., 

   "There exists some Purkinje neuron in the floccular region of the cerebellum that possesses light-to-moderate staining in its somata for PKC-delta."
      http://brancusi.usc.edu/bkms/brain/show-chemodetails.php?idbrain=835&chem=91&state=1

OR

   "The Paraventricular nucleus of the hypothalamus, parvicellular division, medial parvicellular part, dorsal zone (PVHmpd) projects lightly to the median eminence when viewed using bisbenzimide histological staining."
      http://brancusi.usc.edu/bkms/brain/conef-det.php?eff=252&aff=6972

OR

   "Motor neuroendocrine magnocellular vasopressin neurons in the PVHmpd stain for vasopressin."
      http://brancusi.usc.edu/bkms/brain/show-braing2.php?aidi=252

In the latter case, it's the staining for vasopressin that actually is used to identify the neuron type, so clearly such staining is a 'defining' characteristic of the type.

Cheers,
Bill

Subject: bams class style model
 

For another one of my action items, I put on the wiki demo page:
http://esw.w3.org/topic/HCLS/HCLSIG_DemoHomePage_HCLSIG_Demo
a reference to the initial bams class style model and an updated bams 
instance
style model. In both, I made the properties "has_source" and "has_target"
transitive. Please let me know if this is not correct.

There are no instances in the class style model. It is in the style of the
Pizza tutorial
(http://www.co-ode.org/resources/tutorials/ProtegeOWLTutorial.pdf).
You may notice that the model is OWL Full, but that's only because there is 
an
annotation property "has_bams_URL". Reasoners generally ignore annotation
properties.
