Some implementations are still ongoing and we could not include them yet. Especially consumer implementations are taking months to implement, while some of them are even Closed Linked Data and therefore can’t be included as evidence at all.

Feel free to include on-going implementations that seem worth pointing 
out in the usage doc (or we can mention them within the transition 
request that I'll send to the Director). It's good to separate them from 
real implementations, but they still seem useful to show evidence that 
the ontology is being adopted.

We have also documented evidence for the usage of every term in at least one consumer and at least one producer implementation. We have also evidence for 80% of the terms being used in at least 2 (up to 15 for hasFeatureOfInterest) consumer implementations and evidence for 78% of the terms being used in at least 2 (up to 11 for Property and Sensor) producer implementations.

Great! That seems a good plan to me. Process-wise, here is what I need 
to request publication as Proposed Recommendation:

1. An updated Editor's Draft with the ssn-systems module flagged as "non 
normative" and an updated Change History section that summarizes the 
changes since last publication:
  https://w3c.github.io/sdw/ssn/#changes
(I also noted a minor inconsistency in: 
https://github.com/w3c/sdw/issues/958)
2. Some demonstration that all CR exit criteria have been met:
  http://www.w3.org/TR/2017/CR-vocab-ssn-20170711/#exit
3. A record of a group resolution to request publication of the 
specification as Proposed Recommendation. Could you issue a call for 
consensus with a one week deadline as soon as normative changes to the 
spec have been made? (Minor editorial updates to the spec may still be 
integrated during the call for consensus).

As noted in the email I just sent to the group's mailing-list on the 
Time Ontology spec, the SSN spec has a normative dependency on the Time 
Ontology, and thus cannot be published as a Proposed Recommendation as 
long as the Time Ontology has not made it to Proposed Recommendation as 
well. Let's try to synchronize progress of both specs!

Thanks,
Francois.
