Re: Ontology documentation (Graphics)

Hi everyone,

I am usually not in favour of using any tool for generating ontology 
graphics. Mainly because I don't know of any that produces them with 
enough quality and provides flexibility to show only what you want to show.

Therefore, I always end up using some drawing program to make the graphics.

I attach a graphical visualization in Powerpoint of the current version 
of the SSN ontology as an alternative visualization to that produced by 
the COE tool.

In the graphics I have included the ontology modules, but they can be 
removed. Besides, different images could be created for each part of the 
ontology just selecting the relevant ontology components.

The format and the way of representing things is totally open for 
discussion, of course. I just wanted to propose an alternative to the 
current graphics.

The good thing with this approach is that, once we have this first 
version of the graphics, future changes in the ontology can be easily 
implemented. Unless there are major changes in the ontology, the effort 
to update the graphics could be similar to that of the 
modularization+graph-generation process described below.

What do you think?


P.S. In the ontology file (and propagated to the documentation of the 
ontology) there are some repeated classes: DetectionLimit, Drift, 
Precision, ResponseTime, and Selectivity.
