learning cursed knowledge (reading the Owl 2 R·D·F‐Based Semantics specification)
anyway the actually interesting insight wasn’t in that specification but in the specification mapping R·D·F to Direct Semantics which states, with no fanfare, that all owl:OntologyProperty’s (note: this term is not documented) are silently transformed into owl:AnnotationProperty’s (interesting for the insight that properties of ontologies are functionally annotations in their implications)
@Lady You object, at the very least?
@Lady@cat.family it'd be a great event card in the Arkham Horror game, visiting the bookstore: "The book you thought was the Book of Kells is actually the Owl 2 R-D-F-Based Semantics specification. Lose 2 sanity."
if you are wondering how bad it can be, you have clearly never read a Semantics specification
