@evan I see *numerous* discussions about RDF in the transcripts from AS2 SocialWG meetings c. 2014-2015 and I see at least one tracked issue that references the discussions. Yes, AS1 used JSON. However, AS2 uses JSON-LD. Per the JSON-LD spec, "a JSON-LD document is both an RDF document and a JSON document and correspondingly represents an instance of an RDF data model." Based on that, isn't AS2 (and therefore AP) data literally an RDF data model? 🤔 https://www.w3.org/Social/track/issues/21
