WD-Ontology

[Andrea Preite Martinez]

A Working Draft on

Ontology of Astronomical Object Types, version 1.0

has been uploaded in the Document section of IVOA
http://ivoa.net/Documents/latest/AstrObjectOntology.html

and in the Semantics WG twiki page
http://www.ivoa.net/twiki/bin/view/IVOA/IvoaSemantics  .

In this page you can also find the ontology file (.owl) that can be
explored/edited with the protégé browser/editor
http://protege.stanford.edu/overview/protege-owl.html .

The document and the Ontology are open to discussion and contributions.

Note that the ontology is made of "defined" concepts, and only a fraction
of them has been defined, for the moment only in terms of components and/or
morphology and/or processes.
Indeed, there are still 87 astronomical concepts that are missing an  
NS-condition (Necessary&Sufficient)

I then ask for the contribution of the members of the WG and of the scientific
community to help finding the necessary and/or sufficient conditions  
to define the concepts.
What is needed is a complete but concise description in plain text of  
the concepts in terms of components/ morphology / physical processes /  
observational properties and/or ...

An example:
CataclysmicVariable: close binary, components WD/subGiant and LateType Star,
variability due to thermonuclear processes...

The concepts without NS-conditions (but sometimes already with N or S  
conditions) are the following:

P.S.:
I think we can envisage a half-session in the spring IVOA meeting in  
Beijin dedicated to the ontology and its applications.
