Hey, FOAF seems not to be part of the vocabulary package anymore? https://github.com/apache/jena/tree/master/jena-core/src/main/java/org/apache/jena/vocabulary
Is there are reason for this? A copy is present in the SPARQL package: https://github.com/apache/jena/blob/master/jena-arq/src/main/java/org/apache/jena/sparql/vocabulary/FOAF.java It includes archaic terms such as foaf:givenname however, which have new versions: http://xmlns.com/foaf/spec/#term_givenName Could you please regenerate the class? And move back to the main vocabulary package? Thanks. Martynas
