Looks like a bad or lack of proper content negotiation in the Jena call to retrieve the ontology so unexpected HTML is being returned as the representation:

http get 'http://cor.esipfed.org/ont3/api/v0/ont/sbjs/external?uri=http://w3c.github.io/sdw/ssn/'

Well, closing as invalid: the actual ontology URI is: http://www.w3.org/ns/ssn/ as indicated in the Abstract at https://www.w3.org/TR/vocab-ssn/

However, will enter another issue re better error reporting when the provided URL does not resolve to acceptable ontology serialization formats.
