Maxime, can you give me a hand here? I am probably missing something but where does the lower case "feature of interest" label comes from in comparison to the upper case version we used before. Thanks.

Maxime, let us make changes to the code after our discussions and not before them. This is not a race for who gets most commits accepted for the sake of github statistics. @arminhaller @dr-shorthair

Who would race for this ? Sounds childish...
I race for the completion of the action that was assigned to me.
I removed isPropertyOf and hasProperty which need to be discussed in a separate thread.
Now I believe it's ready and acceptable.
If you think otherwise, what shall I update exactly ?

These changes look all good to me. We can discuss the "missing" link between FeatureOfInterest and xxxProperty in our next phone call. I put quotation marks here, because I think it was deliberately left out from SOSA.
In another note, what is the oldssn.ttl in your directory though? Our intention was to only update ssnx.ttl, the alignment between old ssn and new ssn. We don't want to update old SSN at all.

the oldssn.ttl is a copy of the separated/ssn.ttl, that is progressively emptied whenever some terms are added into ssnx.ttl, sosa.ttl, ssn.ttl.
this is described in the steps 1 and 2 of the SOSA/SSN Integration Methodology [1,2]

Indeed, there was no connection between FeatureOfInterest and ObservableProperty in SOSA because that would have involved establishing something akin to the ISO 19109 General Feature Model, which is way beyond the scope of SOSA. It would also have likely involved either rdfs semantics (domain and range) or OWL semantics (owl:Restriction) which we agreed would not be used in SOSA.
