RE: Ontology documentation (Graphics)

Hi Raul,

Thanks again for your slides, this was really useful because I think you found the right level of detail for the presentation of the SSN ontology structure to newcomers. 

You know that since you sent them, the ontology as changed (alignment to DOLCE Ultra lite). Since then, I have published the figures directly generated out of the OWL file on the wiki. But I have found that working simultaneously with PowerPoint and with the COE drawings is quite useful because matching the two results is a good way to check that what is in the ontology corresponds to what you expect it to be.

So here is my revised version of your slides which I think is closer to what's in the current version of the ontology, especially for the 1st figure which represents the alignment to DUL. 

See also the "corresponding" COE schemas recently uploaded:

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.
