@alexl in a graph database, schemas are generally very flexible. From "data blocks" to just attaching your own graph structures… lots of options.

Personally I would want this to happen. Real knowledge graphs profit from holistic networking. If we can add a whole semantic ala #RDFS then we‘d really be starting to go off on the races…

rdfs:isDefinedBy might be a good in-between for owl:sameAs (too strict semantics) and rdfs:seeAlso (too vague).

VHS was the inferior option that took off because of industry adoption rather than technical merit.

When I was considering how painful I find it to work with JSON (I deal with #telemetry feeds pushing TBs of #JSON data every day) I was not thinking of #XML as the alternative. I would prefer strongly typed binary encodings like #Avro or #ProtoBuf.

And for sheer expressiveness, strong-typing and open-ended extensibility I would pick #RDFS.

Via @morganclaypool : The first two editions of "Semantic Web for the Working Ontologist" (@jahendler et.al.) describe #SemanticWeb standards and how they work, their goals, and why they were designed as they are. The third edition builds on this foundation to bring Semantic Web practice to enterprise. https://t.co/7gOsVSYljR #Modeling #OWL #RDFS

66 statements, 66 triples

TopBraid, AllegroGraph and Virtuoso agree on the number of #RDF #RDFS #OWL and #SHACL statements in WF Schema deployed for Glossary of Wildland Fire (#GOWF) PMS205.

While not conclusive proof, I assert it is a reasonable sample of the exercise.
