Dear all,

Here you have an update on the usage of the SSN (1.0) ontology. Some 
people from my research group have filled the form with some more 
ontologies and datasets and I have also taken into account the 
references provided by Amélie Gyrard in her email.

Now the analysis has increased from 2 to 10 datasets and from 9 to 15 
ontologies:
https://w3c.github.io/sdw/ssn-usage/

However, if you take a look at the results, you can see that there are 
still plenty of gaps (i.e., terms for which we don't have implementation).

Therefore, please fill in the form that I created to include those 
datasets and ontologies that you know that are using the SSN ontology:
https://goo.gl/forms/RNZqupczFR14rMEz2

Remember that if the dataset/ontology is available (even through a 
SPARQL endpoint), we can make the coverage analysis for you. So you just 
have to include the link.

Kind regards,
