### Version 4.7.0 ### Feature Currently, riot RDFS inference outputs “generalized” RDF which may not be parsable by other tools (including various Jena CLI tools). For example: `data.ttl` ```ttl PREFIX ex: <http://example.org/> PREFIX xsd: <http://www.w3.org/2001/XMLSchema#> ex:louie ex:birthdate "2022-08-11”^^xsd:date . ``` `vocab.ttl` ```ttl PREFIX ex: <http://example.org/> PREFIX rdfs: <http://www.w3.org/2000/01/rdf-schema#> PREFIX xsd: <http://www.w3.org/2001/XMLSchema#> ex:birthdate rdfs:range xsd:date . ``` Output of `riot --rdfs=vocab.ttl data.ttl` ```ttl PREFIX rdf: <http://www.w3.org/1999/02/22-rdf-syntax-ns#> PREFIX xsd: <http://www.w3.org/2001/XMLSchema#> "2022-08-11”^^xsd:date rdf:type xsd:date . ``` … which is generalized RDF due to the literal in the subject position. It would be nice if there were a flag to filter out such triples (using [SafeGraph](https://github.com/apache/jena/blob/main/jena-core/src/main/java/org/apache/jena/reasoner/rulesys/impl/SafeGraph.java)), so as to avoid errors when subsequently processing the output with tools that don't accept generalized RDF. I’m interested in contributing a solution, but would need some pointers as to where in the codebase this should go. ### Are you interested in contributing a solution yourself?
