Does OpenGraph gain any benefit from its definition as linked data? Or might it just as well have been defined as, say, JSON Schema's and referring to those property names in html?
I'm not expert on OpenGraph, and it's been a while I've actually manipulated RDF other than the automatically generated og meta tags.
I'd say defining this as linked data was quite idiomatic / elegant. It's possibly mainly because OpenGraph was inspired of Dublin Core [1], which was RDF-based. They didn't reinvent everything with OpenGraph, but kept the spirit, I suppose.
In the end it's probably quite equivalent.
And in this end, why not both? Apparently we defined an RDF ontology for JSON schemas! [2]
