Publish ssn-ext WD - was RE: Recap Toulouse face to face

I wonder if we could progress this now. 
The goal would be for to be superseded by the content currently at 
Is that something that the chairs can now give Ted the OK on?

Hi all, 

Probably everyone is on holiday now, but I'll just send you my thoughts. 

I don't feel the need to do a call for consensus, since we had the face to face and since then we've had some feedback via github (which has triggered some minor updates), ergo enough exposure. 

However I'm wondering about two things: 
1) the plan to publish this extension in the main ssn namespace., do you have any new input on this? 

2) (longer term) if we start treating SOSA/SSN as an evergreen standard, we need to figure out how this relates to the OGC standards process, where something like that doesn't exist (yet).

Onderwerp: Re: Recap Toulouse face to face

Hi Simon,

As it was previously a [First Public] Working Draft I requested permission to publish it as a Working Draft. Some prefer WD to Notes as having more weight as a specification although that is a matter of perception. I spoke with Philippe Le Hegaret with his Director hat on and he is inclined, awaiting email confirmation.

I viewed the support for the updates presented at the face to face as approval but Linda or Jeremy may wish to formalize with a call for consensus. That can be done simply as an email to this list with a deadline, typically five business days as I recall, to voice objection.
