In the final days of the JSON-LD 1.1 WG an attempt was made to put a NOTE together for a "CBOR encoding for JSON-LD", which is slightly different from what CBOR-LD is attempting to do (compression is a big focus of CBOR-LD, not just encoding JSON-LD into CBOR). The group had been (rightly) prioritizing getting JSON-LD 1.1 and associated algorithms shipped. The JSON-LD 1.1 WG, with a huge thanks to Gregg Kellogg, did yeoman's work getting us to an updated version of JSON-LD 1.1. The official JSON-LD 1.1 Recommendation was finalized just a week ago: https://www.w3.org/TR/json-ld11/ So, the difference is that the document worked on by the WG was a way to encode JSON-LD in CBOR, whereas the thing that was just announced on this mailing list was a way of compressing JSON-LD into a new format called CBOR-LD that would enable a reduction in file size AND possibly an increase in compute speed (neither of those were goals of the format considered by the JSON-LD WG, IIRC). I hope that CBOR-LD (the most recent announcement) will be what we focus on as the months roll on... but I say that not having discussed any of this with the JSON-LD WG... we'll have to see what Ivan, Gregg, and our friends over there think about this new approach. Additionally, we need to chat with Pierre-Antoine, who I believe did a lot of the work on JSON-LD-CBOR to see if he feels there are key design criteria that we missed when we put CBOR-LD together. -- manu -- Manu Sporny - https://www.linkedin.com/in/manusporny/ Founder/CEO - Digital Bazaar, Inc. blog: Veres One Decentralized Identifier Blockchain Launches https://tinyurl.com/veres-one-launches
