However, I have argued in the same email that there was no *strong* objection in the F2F against SOSA (and no one has raised their voice to say otherwise). There is potentially your objection, Kerry, but I am not sure if it is against the name or the fact that it is a different namespace (which is a separate issue to be resolved) and that it is used as the prefix in SOSA. I have further argued that we have much more pressing issues that need our attention rather than wasting our valuable telco time on preferences for names, and further, I recall Phil shouting out in the telco that we need to find a strong reason to create another and at the same time retire an already W3C created namespace. Unless SOSA is offensive in some language or we decide on only using one namespace (a much more important issue to resolve), I am not intending to table the naming issue until our F2F.

I cannot even find it as a github issue (although it was clearly called SANDA for a while there).

The mapping table (to  which I have contributed )  is misleadingly simple as it is only about (a small subset of) the descriptive annotations attached to  some classes and properties. It is useful as it is, but falls far short of an analysis of the difference in meaning of the terms between sosa and ssn. I know this because I have done at least a partial analysis and raised issues on the tracker accordingly (as was requested by the chair). I am not going to speak for others, but a good few people have made similar remarks on the list. SOSA is indeed  very simple, quite small, and is reasonably ok as it stands in a self-contained way.  It will be used. But the  "overriding issues" as I see it are all about  how it behaves as a '"core" of ssn that is was always intended  to be -- in fact a "module" of ssn that forms the core.  Actually , SSN is much closer to O&M than SOSA  is-- ssn reuses O&M terms almost everywhere it can  wheras SOSA does not (again, see tracker issues for each SOSA term). Should ssn go backwards in this way in order to use SOSA terms with no heritage at all? And SOSA fails to acknowledge OGC's sensorml at all (unlike ssn).  SSN also reuses from several other ontologies and vocabularies  in the area ( the standard VIM, & MMI are the main ones).

Separate specs and they just don't play together.  Then it is easy to modularise  ssn   and to extract a core, taking advantage of the learning we have made around sosa, and without  having to deal with all the incompatibilities.  At this point I have to see this as a serious option.

The question has in fact never been asked, let alone revisited, despite the fact that I asked it to be discussed and despite the fact that several people have expressed some concern with “SOSA” (and I am not going to speak for their opinions.)   Can you point please to some evidence that it was decided? And note that I asked it to be dicsussed well before it was written into the current WD, without discussion, so I’m just covering here for a possible statement  that  we all agreed with the evidence that it is in the current WD that we voted for.

New-SSN will differ in many regards from old-SSN because we have changed axioms and also removed many, many of them. This may or may not affect your specific ontology and data depending on whether you made use of these parts of SSN or not. New-SSN and old-SSN entailment differs.  New-SSN has its own new namespace. The existence of SOSA does not affect your data at all.
