No need to import SKOS - was RE: tidying ssn -- are you ok with?

I added a SKOS import locally at one stage just to add SKOS properties to my tool’s menus. Was never intended to stay.

AFAICT you only need to import if your ontology depends on the axiomatization of the imported ontology.
SOSA/SSN do not depend on SKOS since they will only use some annotation properties.

Dear all,

+1 for Kerry's (a) :
 - (a) use skos:example and declare it an owl  annotation property (and this will work for any other skos property too). Also don’t import skos.

My arguments are:

 - SKOS is just used for documentation purposes here. So declaring skos:example, skos:definition, skos:note as annotation properties suffice in our case;
 - we don't need of all SKOS axioms. Importing all of them will make SOSA/SSN more complex to browse in Protégé for example;
 - the users of SOSA/SSN will import SOSA/SSN, but they do absolutely not need to import SKOS axioms.

Kind regards,
Maxime

I am certainly fine with SKOS if this is what most of us prefer. Armin, can you put this onto our agenda for the next call?

Btw I never intended to claim that skos was ideal here, but it was convenient to separate out the different annotations,. A simple SPARQL update could then finalise it to the predicate/namespace of choice.

Hi Kerry,

I think it would be great if we could discuss this in the group meeting next week. I would like to understand our motivation a bit better as well as some decisions that we are taking e.g., using skos:example without importing skos.

Have a nice weekend

I’d like to follow the approach Simon used in sosa (as we discussed in a meeting last year, I think) to separate examples from descriptive comments in the ontology using skos:example.

Are you ok with me doing the same in ssn? I don’t  plan to change the content substantively (although I might reword an example a little if it seems a bit too hard to follow e.g. too brief). And I’m not going to add amore examples at this point --- just move the ones already there.

I will not import skos.

Btw– I think this means specgen that we are currently using for the spec doco will no longer be able to extract the example – nor for sosa .
