Posted on CG blog on it. 17:07:21 i/scribe+/scribe: anatoly-scherbakov 17:07:21 ack manu 17:07:21 q+ to also say hi 17:07:25 manu: hello and greetings! 17:07:35 ack dlongley 17:07:35 dlongley, you wanted to also say hi 17:07:36 RRSAgent, draft minutes 17:07:37 I have made the request to generate https://www.w3.org/2023/12/13-json-ld-minutes.html TallTed 17:07:51 dlongley: great to see everyone! 17:07:59 topic: Updates from the CG 17:08:16 niklasl has joined #json-ld 17:08:18 bigbluehat: any further updates from the CG for Dave and Manu? 17:08:20 present+ 17:08:34 gkellogg: CG was working on YAML-LD, and driving JSON-LD issues. 17:08:51 gkellogg: Latest ones revolve around `@nest` and scoped contexts. 17:09:18 gkellogg: We introduced CBOR-LD a few weeks ago and discussed it a bit last week. Looking forward to hear about DigitalBazaar's work on that. 17:09:22 q+ 17:09:32 ack pchampin 17:09:36 bigbluehat: thanks! A lot of work has accumulated to the point that we're looking into formalizing it. 17:09:54 q+ 17:10:06 ack niklasl 17:10:07 pchampin: I discussed with colleagues about Linked Data in WoT scenarios; they're interested in CBOR-LD and might join the WG. 17:10:38 niklasl: we've been talking about JSON-LD-Star and RDF-Star and thinking how to integrate these. 17:11:10 topic: Plans/desire to publish Best Practises doc, YAML-LD, and a CBOR-related specification 17:11:49 bigbluehat: Let's start with low-hanging fruit 17:11:53 subtopic: Best Practices 17:12:11 s/Best Practises/Best Practices 17:12:14 https://w3c.github.io/json-ld-bp/ 17:12:22 bigbluehat: the question about Best Practices has been there for a while. Do we need to post it as a separate note? 17:12:48 current charter: https://www.w3.org/2023/01/json-ld-wg-charter.html 17:13:01 pchampin: I agree; I need to check with the charter and not everyone might agree 17:13:15 q+ 17:13:34 ack gkellogg 17:14:12 gkellogg: there was never a resolution to publish the BP as a Note. It shows the last published version and that leads to a 404. Might be a problem with ReSpec 17:14:40 gkellogg: we can certainly publish it as a Draft Note, even if it is incomplete 17:15:01 gkellogg: there is also a Best Practices document in the CG but it's been removed from the UI 17:15:04 bigbluehat: do they differ? 17:15:09 gkellogg: they're different 17:15:40 bigbluehat: maybe some resolving is in order. The Charter only spells out maintenance of JSON-LD normative documents and also allows non-normative documents 17:16:03 bigbluehat: to make YAML-LD and CBOR-LD normative we need to move formally as a group to re-charter 17:16:12 q+ 17:16:20 subtopic: YAML-LD 17:16:25 scribe+ 17:16:25 scribe+ 17:16:40 anatoly-scherbakov: nice to meet Manu and Dave 17:16:41 scribe- 17:16:59 ... is it ok for the group to be named JSON-LD if we extend the scope to YAML-LD, CBOR-LD... ? 17:17:15 ... Should we find an Umbrella term? 17:17:28 I agree with Anatoly, we should shift the WG name given the expanded scope. 17:17:30 q+ 17:17:31 JSON-LD and others! WG :)? ... JSON-LD and Derivatives WG (doesn't sound as friendly) 17:17:34 ... Also other formats such as CSV, Parquet... could be addressed. 17:17:36 ack anatoly-scherbakov 17:17:38 ack manu 17:17:51 manu: agree with Anatoly, makes sense to rename the group to focus on expanded scope 17:17:52 Expanded JSON-LD Universe WG 17:17:56 q+ 17:18:00 ack gkellogg 17:18:20 gkellogg: there is a standard for CSV for LD, its ten years old and has moderate use 17:18:34 q+ 17:18:53 https://www.w3.org/TR/tabular-data-primer/ 17:19:00 gkellogg: "tabular data on the web" it is. It probably needs to be revisited, needs periodic updates. I think though that CBOR is definitely inspired by JSON, YAML and JSON developed together 17:19:25 gkellogg: it might be confusing to try to come up with some other name (Linked Data Working Group? - that is too broad maybe) 17:19:30 JSON-LD Umbrella WG 17:19:41 gkellogg: but we can probably stick with the JSON-LD as group name as we're working on things closely related to JSON-LD 17:19:53 q+ 17:19:57 ack niklasl 17:19:58 bigbluehat: agree, and let's move on though 17:20:29 niklasl: I agree this is a tricky question; I am leaning towards what Gregg said. One the reasons of JSON-LD success is because it is RDF channeled through JSON 17:21:25 CSV on the web came out before JSON-LD 1.0 was standardized 17:21:45 niklasl: CSV on the Web saw lower adoption. Something about JSON is very useful, I do not know how to call it more abstractly so that it rings as well as it does now 17:22:02 niklasl: there's something in the simplicity of JSON-LD itself 17:22:12 INFRA-LD 17:22:19 niklasl: leaving JSON behind we miss the point how we got here 17:22:21 ack pchampin 17:23:11 "Not-XML-LD" 17:23:13 JSON-LD and Friends 17:23:13 q+ 17:23:15 pchampin: My own opinion: I agree Tabular Data on the Web would deserve a refresh. Having one group for all kinds of data formats wouldn't be optimal though. We are focusing on JSON, one particular shape of data 17:23:15 agree that we need to focus in the new WG. 17:23:24 +1 17:23:40 pchampin: other concerns, other languages, should probably be addressed by other groups 17:24:04 pchampin: JSON-LD WG should care about JSON and very similar formats 17:24:08 +1 that JSON-LD is the unifier / north star / commonality 17:24:24 bigbluehat: thanks everyone! Let' 17:24:27 ack bigbluehat 17:24:32 bigbluehat: thanks everyone! Let's keep JSON in focus 17:24:33 rssagent, make logs public 17:24:46 rssagent, generate minutes 17:24:56 q+ 17:25:02 ack manu 17:25:04 bigbluehat: CG report for YAML-LD published, thanks Gregg! what's the future of this format in the WG? 17:25:13 rrsagent, generate minutes 17:25:15 I have made the request to generate https://www.w3.org/2023/12/13-json-ld-minutes.html gkellogg 17:25:21 +1 to YAML-LD going standards track 17:25:28 manu: I support YAML-LD to go to Standards Track, as long as someone can help moving it through the process 17:25:59 manu: it provides a signal that we're onto something, these patterns are useful in other syntaxes, it allows the RDF data model to shine 17:26:19 manu: in the other syntaxes you can express the same data model: JSON-LD - YAML-LD - CBOR-LD and back, that's a good thing 17:26:45 manu: we should take this to Standards Track. What about implementations? 17:26:46 q+ 17:26:50 scribe+ 17:27:09 anatoly-scherbakov: the first implementation of YAML-LD is probably gkellogg's 17:27:26 ... I'm developing a Python implementation, based on PYLD, alpha stage at this point. 17:27:54 ... It passes the YAML-LD test suite. My next step is to run the JSON-LD test suite. 17:28:19 ... I'm using it in a little project of mine: browser and knowledge workspace for LD, mostly based on YAML-LD. 17:28:35 scribe- 17:28:39 niklasl: this gets us two baseline implementations. Moving through WG will be about that. Any other notices about implementations? 17:28:48 subtopic: CBOR-LD & JSON-LD in CBOR 17:29:28 https://w3c.github.io/json-ld-cbor/ 17:29:34 niklasl: let's move on to CBOR-LD. The questions about it are centered about progressing CBOR-LD spec to match implementations 17:29:39 https://digitalbazaar.github.io/cbor-ld-spec/ 17:29:46 q+ 17:29:49 bigbluehat: what level of compression should we use? 17:29:50 ack anatoly-scherbakov 17:29:51 q- 17:29:54 ack manu 17:30:06 Introduction to CBOR-LD: https://lists.w3.org/Archives/Public/public-json-ld-wg/2020Jul/att-0004/Introduction_to_CBOR-LD.pdf 17:30:25 s/niklasl: let's move/bigbluehat: let's move 17:30:30 q+ 17:30:40 i believe there are three implementations, one in Rust, one in Java 17:30:44 manu: putting the link about CBOR-LD abortions. There are presentations from 2020 we published, they go over the basics. CBOR-LD has 2-3 implementations so far: JS, Rust and something else 17:30:46 one in JavaScript 17:31:21 manu: primary reason was Verifiable Credentials, we had a program in the US with the National Association of Convenience Stores about digital age verification program 17:31:34 manu: the goal was privacy preserving age verification 17:31:57 manu: so that we can prove your age without disclosing any other PII 17:32:35 manu: that was in 2018-2019. One of the things they needed was ability to scan the verifiable credential which was a JSON-LD document 17:33:01 manu: thus we needed a very high density bar code so that the old hardware can scan and handle it, we needed to get a JSON-LD document down to 350 bytes 17:33:31 manu: that's why CBOR-LD came into existence, we needed to compress digitally signed JSON-LD so that it could fit into a QR code. We're now in production 17:34:13 manu: about 4-6 months ago, California department of Motor Vehicles launched their digital driver's license which includes a CBOR-LD QR code 17:34:35 manu: in California you can now show that QR code which is CBOR-LD and prove your age 17:34:48 Well IMHO that's really super cool 17:35:11 manu: the rollout is still happening but I wanted to make a point that it is already in production and in practical use 17:35:21 s/Well IMHO/anatoly-scherbakov: Well IMHO 17:35:35 RRSAgent, draft minutes 17:35:37 I have made the request to generate https://www.w3.org/2023/12/13-json-ld-minutes.html TallTed 17:35:43 manu: we put a version number on the version that's out there so that W3C WG can introduce breaking changes in a new version 17:35:58 manu: spec is not in a good shape, it is out of date from the implementation 17:36:14 s/rssagent, make logs public// 17:36:20 q+ to quickly mention that existing implementations include a non-compression mode 17:36:22 s/rssagent, generate minutes// 17:36:23 -q 17:36:26 q- 17:36:33 manu: we've talked about the plan to merge the changes in current spec and the reality of implementations 17:37:01 manu: we have an uncompressed mode in the spec. Even that saves a number of bytes, but compression is what the real users are interested in 17:37:05 RRSAgent, draft minutes 17:37:07 I have made the request to generate https://www.w3.org/2023/12/13-json-ld-minutes.html TallTed 17:37:19 manu: we also are working with governments about integrating CBOR-LD into their digital ID systems 17:37:40 manu: that's kind of where we are with CBOR-LD 17:37:44 ack gkellogg 17:37:45 s/dlongley, you wanted to also say hi// 17:38:26 gkellogg: I think the two different documents address different things. Pierre-Antoine's expresses basic JSON with CBOR compatible with JSON-LD. DigitalBazaar's version is mostly about how you provide that with semantic compaction. 17:38:43 gkellogg: YAML-LD sets a pattern we probably want to stick with — it is mostly API centric 17:39:11 gkellogg: it mostly involves transformation between YAML and JSON-LD Internal Representation. Compression doesn't happen in CBOR, it can happen in Internal Representation 17:39:52 gkellogg: A concern I had: CBOR-LD 1.0 version doesn't have a parallel in core CBOR 17:39:54 q? 17:40:07 q+ to say that current implementations have tags and versions 17:40:12 pchampin: Gregg summarized this very well 17:40:12 ack dlongley 17:40:12 dlongley, you wanted to say that current implementations have tags and versions 17:40:31 dlongley: about magic numbers: current implementations have tags indicating their CBOR-LD and version numbers 17:40:44 dlongley: implementations support that; not sure if spec reflects it 17:41:42 q+ 17:41:44 gkellogg: the current spec doesn't detail that. Not sure how the tag structure with JSON-LD in it extracted from a CBOR document is distinguished against any other CBOR structure 17:41:46 ack manu 17:42:26 manu: CBOR has a registry, tags are registered there, what we need is to request new numbers in the registry which are granted on first come first serve basis. You don't need an official structure to claim them 17:42:52 manu: if we're an official WG it makes it even easier to register our signature bytes in the CBOR tags registry 17:43:41 bigbluehat: do we want to move forward as chartered, keeping YAML-LD as a Note or a Draft Note, and bringing CBOR-LD spec to the status of a Note? 17:43:54 q+ 17:44:03 bigbluehat: or we feel we are ready to bring these to Standards Track sooner and recharter the WG at this point? 17:44:09 subtopic: rechartering? 17:44:12 ack gkellogg 17:44:26 q+ 17:44:33 gkellogg: I think there is sufficient implementation done for both to move to the Recommendation Track 17:44:34 +1 to gregg 17:44:44 q+ to speak to level of effort for CBOR-LD and current production trajectory 17:45:00 gkellogg: I do not know if publishing CBOR-LD as a Note makes a difference. Bringing it to Rec Track will improve visibility and hopefully drive participation 17:45:22 gkellogg: Updated Charter should also help other things, like fostering JSON-LD specs 17:45:49 gkellogg: Charter doesn't specifically need to mention RDF-Star 17:45:53 ack pchampin 17:46:07 bigbluehat: currently the charter only calls for maintenance, i.e. non breaking changes 17:46:24 pchampin: errata is appropriate; not sure how breaking a change might be to fix a bug 17:46:36 RRSAgent, draft minutes 17:46:37 I have made the request to generate https://www.w3.org/2023/12/13-json-ld-minutes.html TallTed 17:46:45 pchampin: the Note track and the Rec track are meant for different kinds of documents 17:47:04 pchampin: it would be a pushback if we post a spec as a Note and then move it to Rec 17:47:09 s/dlongley, you wanted to say that current implementations have tags and versions// 17:47:41 pchampin: it is Rec material. Falling back to Note track if we are not allowed to push it to Rec wouldn't work. It is a document meant to be a Recommendation, not a Best Practices, not a Note 17:47:53 pchampin: even if we could, having it on Note track can do it better than a CG report 17:48:01 q? 17:48:11 pchampin: we will continue working on it in the CG of course until the WG is allowed to take it to Rec track 17:48:11 ack manu 17:48:11 manu, you wanted to speak to level of effort for CBOR-LD and current production trajectory 17:48:39 manu: we want to move CBOR-LD out of digiatlbazaar github repo and move it to JSON-LD Github repo 17:49:20 manu: can we do that? secondly, CBOR-LD is way behind where YAML-LD spec is. Problem is, many of us are heads down in Verifiable Credentials WG trying to get about five specs to Rec track 17:49:35 manu: we do not have much bandwidth to work on this spec. Maybe it becomes easier next summer 17:50:05 manu: we're discussing going into production with CBOR-LD systems with national and state governments. They don't necessarily want to wait until the standard is done 17:50:26 manu: but they want an acknowledgement of W3C that W3C is looking forward to standardize CBOR-LD 17:50:33 q+ 17:50:38 q+ 17:50:58 manu: CBOR-LD as a Note doesn't make a lot of sense, we'd like it to go to Rec track 17:51:28 manu: a new WG charter mentioning CBOR-LD could be a signal to the governments and buy us a bit of time to get the spec into proper shape 17:51:59 manu: YAML-LD is further along and we could recharter the group putting both in scope, and focus on YAML-LD first then switching to CBOR-LD later 17:52:10 manu: and we only have 6 months to get CBOR-LD done 17:52:27 +1 17:52:31 manu: publishing a new charter would be a positive signal to the community that we're working on these 17:52:33 ack niklasl 17:52:33 +1 17:53:03 q+ 17:53:13 niklasl: sounds like a good idea. I think what we define should be very minimalistic, kind of glue code defining the serialization. 17:53:45 niklasl: this could also say that JSON-LD is beyond JSON. Contextual Compaction of Linked Data with a kind of Framing is the overarching theme here 17:53:56 ack bigbluehat 17:54:17 bigbluehat: suggesting we take an action today to bring CBOR-LD into CG space 17:54:34 bigbluehat: let's start its life there, it will need much discussion and activity 17:54:40 ack gkellogg 17:55:03 gkellogg: nominally it's a CG action but we are highly overlapped and we can resolve to do that 17:55:40 agree, gkellogg -- we should write all of the concerns / issues we have down into the issue tracker 17:55:46 gkellogg: manu mentioned that there are open issues with the spec. Would be great if github issues reflect those. this will make it easier for people to contribute 17:56:06 PROPOSAL: Bring Digital Bazaar's CBOR-LD 1.0 editor's draft https://digitalbazaar.github.io/cbor-ld-spec/ into the JSON-LD CG for future work. 17:56:13 +1 17:56:14 +1 17:56:14 +1 17:56:14 +1 17:56:15 +1 17:56:16 +1 17:56:19 +1 17:56:20 +1 17:56:22 +1 17:56:31 RESOLVED: Bring Digital Bazaar's CBOR-LD 1.0 editor's draft https://digitalbazaar.github.io/cbor-ld-spec/ into the JSON-LD CG for future work. 17:56:41 technically, "adopt Digital Bazaar's CBOR-LD" 17:56:44 rrsagent, generate minutes 17:56:45 I have made the request to generate https://www.w3.org/2023/12/13-json-ld-minutes.html gkellogg 17:56:58 bigbluehat: resolved. David you apparently hold the super powers, can you do the actual moving please? 17:57:12 dlehn: eventually it will be moved to W3C and we will have to move it again? 17:57:34 gkellogg: yes if the WG is rechartered. We'll move the repos from the CG to the WG github org, but this might take months 17:57:58 dlongley: this will mean broken links 17:58:11 s/dlongley: this will mean/dlehn: this will mean/ 17:58:41 bigbluehat: we can't get it into W3C repo now because it is CG material 17:59:08 bigbluehat: there is an ambient consensus about rechartering 17:59:10 gkellogg: let's do a proposal 17:59:37 PROPOSAL: Recharter the JSON-LD WG to focus on YAML-LD and CBOR-LD 17:59:41 +1 17:59:43 +1 17:59:43 +1 17:59:43 +1 17:59:46 +1 17:59:47 +1 17:59:47 +1 17:59:53 +1 17:59:56 +1 (not excluding RDF-star alignment?) 18:00:24 RESOLVED: Recharter the JSON-LD WG to focus on YAML-LD and CBOR-LD 18:00:25 bigbluehat: this resolution doesn't need to be exclusive, it just signals we want to recharter 18:00:45 bigbluehat: we are still continuing the maintenance of JSON-LD core specs and other things 18:00:53 rrsagent, draft minutes 18:00:54 I have made the request to generate https://www.w3.org/2023/12/13-json-ld-minutes.html manu 18:01:06 bigbluehat: we'll likely not have another CG call before the end of the year, we'll get back to this in January 18:01:13 s/manu, you wanted to speak to level of effort for CBOR-LD and current production trajectory// 18:01:28 rrsagent, generate minutes 18:01:29 I have made the request to generate https://www.w3.org/2023/12/13-json-ld-minutes.html gkellogg 18:01:35 rrsagent, pointer 18:01:35 See https://www.w3.org/2023/12/13-json-ld-irc#T18-01-35 18:02:47 Zakim: adjourn meeting 18:03:01 Zakim: end meeting 18:03:11 Zakim, end meeting 18:03:11 As of this point the attendees have been TallTed, dlehn, bigbluehat, gkellogg, dlongley, anatoly-scherbakov, pchampin, niklasl 18:03:13 RRSAgent, please draft minutes 18:03:15 I have made the request to generate https://www.w3.org/2023/12/13-json-ld-minutes.html Zakim 18:03:21 I am happy to have been of service, bigbluehat; please remember to excuse RRSAgent.
