Yes, the stability question has been raised as a consideration and  does condition some of our options.  I have taken an action to look into it (ACTION-210)

Keep in mind that the work original known as DUL has moved in other directions (namely patterns). To the best of my recollection, DUL has not been maintained since 2010 or 2011 and there is (to the best of my knowledge) no governance structure in place. This broke the original SSN at some point (the URL went offline). If we want to have an official DUL alignment in whatever form, we should make sure we understand the issues and ontological commitments that come with it. What are the advantages of having a DUL alignment in the SSN domain?

Best,
Krzysztof

P.s. Btw, since about 3-4 weeks, we started to go in circles and revisit issues we discussed in March.

Hi all,
+1 for having such alignments published separately but in the same domain of SSN

Reposting discussion on status of dolce alignment to the list as it came up in ssn meeting today. Since then, and under Armin's table presented today, another option would be to have the dolce alignment (and other alignments) published as non-normative in the rec-track/standard.

Kerry,

Resending the content from my other response to you on this topic for the consumption of the WG.

"In OGC, a few options are possible. If the SSN work is to become an OGC standard, then DUL could be published as an extension (full weight of a standard, but optional component), a Best Practice, or a Discussion Paper. If SSN is to be a Best Practice, then it is most appropriate to make DUL a Discussion Paper.”

Best Regards,
Scott

Now we want to publish SSN minus DUL and minus alignment as the standard, but also separately publish the alignment ( probably still  importing DUL) as something weaker.
