Although to be fair, evidence of multiple implementations is “favorably viewed” in the context of standard adoption.

Kerry, 

No evidence of implementation is required for an OGC standard. We do have a standards track that includes a "standard with compliance suite" that is more mature than a "standard," but that requires an OGC maintained compliance test suite in addition to reference implementations. 

Best regards, 
Scott

As discussed at the Lisbon F2F and again at in the ssn meeting this morning (or yesterday for many, see minutes https://www.w3.org/2016/08/23-sdwssn-minutes ), 

we require proof of implementations for W3C Rec track deliverables. This is defined in the W3C process here https://www.w3.org/2015/Process-20150901/#rec-advance . 



Phila has advised that there is no more formal definition of what an implementation means for a vocabulary deliverable. However, he points us to these two successful precedents 



(1) The implementation report for Prov is at https://www.w3.org/TR/2013/NOTE-prov-implementations-20130430/ - and is very impressive. It's more than is required but they had a whole stack to prove, we just have a vocabulary. 



(2) The implementation report for the ORG ontology might be a better example, see https://www.w3.org/2011/gld/wiki/ORG_Implementations . 



In my opinion, we can use the latter style. I know for the former this was put together through a survey call (I was one of the implementation contributors). In our case I expect we would be smarter to do an analysis ourselves of public material, starting now, and then work harder to source (through a survey or through explicit soliciting for implementations) for the rest – ie anything that we cannot find in the published material plus anything we might add to ssn here. I suggest this strategy because I believe we can get a very long way, faster, sooner, by analysing public material (and this could save us a lot of time at the CandidateRec -> Rec stage later on) . However, * if * we agree with this approach, we also need a volunteer to take on the task. This might be a particularly attractive task to someone fairly new to ssn who wants to see how it is used. 



Is this a reasonable approach? Will you volunteer? 



@Scott – by this asking kindly whether there may be some OGC principles for implementation of standards that we additionally need to satisfy.
