Thank you for that Raul. I will do so and I hope others will too. For the "call" we were just trying to start early as if we do not get implementations of every term we will have a lot of work to do to undo stuff. So we are indeed looking for a localised informal call for help -- and starting with the WG itself as you have done is a very good place. However, if you can think of some non-WG people to co-opt for contributions too this would be greatly appreciated. --Kerry -----Original Message----- From: Raúl García Castro [mailto:rgarcia@fi.upm.es] Sent: Thursday, 8 December 2016 3:32 AM To: public-sdw-wg@w3.org Subject: Re: Usage of the SSN ontology Dear all, Regarding the title of the new ACTION-228 (To put out a general call for existing implementations), from what I understand of the W3C process, issuing a call for implementations is something that you do once the document is a Candidate Recommendation. Therefore, we are not yet there with the SSN ontology. However, in order to continue with this, I have prepared a form to include existing implementations of the SSN ontology, in terms of the datasets and ontologies where the vocabulary terms have been used: https://goo.gl/forms/RNZqupczFR14rMEz2 Then, I propose to follow the next steps: 1.- Everyone in the group fills the form to include their existing implementations of SSN 1.0. Not yet an open call but allows us advancing the work and seeing potential features at risk. 2.- Once we publish the SSN Candidate Recommendation, we send out a call for implementations of SSN 2.0. This one will be distributed broadly and we will have to update the form with the new vocabulary terms. Please, take a look at the form and give any feedback on it (as well as on the steps proposed.
