20:15:35 q+ 20:15:38 q+ 20:15:41 ack roba 20:16:17 roba: I concur - the issue about a data model with multiple serialisations is interesting, and RDF is a good canonical model because it is lossless 20:16:51 ... but the issue here is that if you want extensions to DCAT then an application profile is required. 20:17:22 ... we haven't provided any guidance on this (e.g. for geoDCAT-AP etc) 20:17:41 ... and I think that it's a weakness not to have this in scope 20:17:44 q+ 20:18:03 ack annette_g 20:18:18 rrsagent, create minutes v2 20:18:18 I have made the request to generate https://www.w3.org/2022/10/11-dxwg-minutes.html DaveBrowning 20:18:43 annette_g: agree that there is a difference between spec and implementation - worth putting a note in regarding how to use it 20:18:55 https://www.w3.org/TR/vocab-dcat-3/#security_and_privacy 20:19:22 we recommend that people publish checksum 20:19:29 q? 20:19:33 q+ 20:19:33 ack riccardoalbertoni 20:20:18 riccardoalbertoni: we have a section on security and privacy - please look and suggest improvements if required. 20:20:31 https://docs.google.com/document/d/1WX1TVE22AaUOSSkjunI9tvXFVF6gj5AhCVJsPHTrYXw/edit?usp=sharing 20:20:43 does the response suffice? 20:20:48 q+ to talk about the checksums in particular 20:21:20 we acknowledge the issue but its not in scope.. 20:21:44 ack roba 20:21:47 they are asking specifically re RDF integrity 20:22:59 roba: 3 things: 1/ response needs to be clear about scope early in the draft; 2/ checksum is not the only way of checking so perhaps it should be provided as an example of determining intergrity; 3/ is there anything in the W3C canon that addresses it 20:23:02 https://w3c.github.io/rch-wg-charter/explainer.html 20:23:57 roba: perfect - lets just reference this 20:24:08 q? 20:24:16 ack annette_g 20:24:16 annette_g, you wanted to talk about the checksums in particular 20:24:51 annette_g: i dont see anything re security there.. 20:25:16 PWinstanley: once you have a canonical form you can do checksums 20:25:50 checksum for integrity 20:26:05 q? 20:26:16 riccardoalbertoni: DCAT talking about checksums for distributions - not DCAT metadata 20:27:06 annette_g: nothing in security and privacy re checksums - can we add a note ? 20:28:06 q+ 20:28:14 ack annette_g 20:28:55 annette_g: analagous to software - checksum for each distribution 20:29:41 s/analagous /analogous/ 20:29:47 roba: problem is metadata is designed to sit above distributions 20:30:47 riccardoalbertoni: summary - we cannot do much in this direction 20:31:32 PWinstanley: 1 - state its not in scope of model, 2 - point to new community group 20:31:52 3 - thanks for feedback and note timeliness 20:32:05 q+ 20:32:40 4 - may rely on canonical serialisation and is a significant technical challenge 20:32:53 ack annette_g 20:33:16 annette_g: should we give people a note on how to use a checksum 20:36:05 rrsagent, create minutes v2 20:36:05 I have made the request to generate https://www.w3.org/2022/10/11-dxwg-minutes.html DaveBrowning 20:38:20 annette_g: i dont read it as about integrity of DCAT - is it about someone else publishing a different DCAT record with a different checksum? 20:38:54 PWinstanley: can we seek refinement of the issue to clarify its scope 20:39:49 roba: as i read it the wording implies its about the integrity of the DCAT and hence the checksums for the distributions. 20:40:31 annette_g: i dont care about a checksum on the metadata - want to provide guidance on implementation on checksums 20:41:07 roba: need to avoid specifying an implementation 20:41:26 PWinstanley: make sure its clearly an example 20:42:57 TOPIC: content negotiation by profile 20:44:37 roba: both ConnegP and the profiles vocab are being used in OGC and a series of Australian Gov LD projects. 20:45:25 ... There is no published DCAT profile that allows for the description of the conformance of the data - no standard practice 20:45:56 ... Handling multiple representations is forward thinking, and it is at the API level 20:46:25 ... the implementation is working "well enough" in its current form 20:46:52 ... and there are no competitors. So we are waiting for requirements to emerge 20:51:40 q+ 20:51:45 ack annette_g 20:52:02 roba: we have two independent implementations - but nothing in the wider community is obviously ready for semantic interoperability in this detail. 20:53:14 PWinstanley: fundamental "soft sand" around definition of a profile. 20:53:27 e.g. data profile only? 20:54:26 PWinstanley: issues with IETF and the use of HTTP headers 20:54:54 proposal to remove HTTP as normative 20:55:34 q+ 20:55:51 ack roba 20:56:15 roba: there are any number of philosophical discussions about what's a profile, you could possibly add in extra classifications. 20:56:32 The big issue is that this was originally meant to dovetail with an IETF process, which is stalled. 20:57:02 The two independent implementations we have eare around the QSA approach. There is a proposal to take the http part of out the specification. 20:57:07 roba: there are all sorts of views on what a 'profile' is, but the big issue is that there is a stalled IETF process and at present there doesn't seem to be any route to developing the HTTP model further. 20:57:29 s/eare/are 20:57:38 ... There is also no alternative functionality we can reference. 20:58:12 ... The model is ready to go, and will operate whether using HTTP or QSA 20:59:05 ... The recommendation looks ready to go from the QSA perspective, and we could dissociate the HTTP angle and deliver an effective recommendation. 20:59:35 rrsagent, create minutes v2 20:59:35 I have made the request to generate https://www.w3.org/2022/10/11-dxwg-minutes.html DaveBrowning 21:04:26 rrsagent, create minutes v2 21:04:26 I have made the request to generate https://www.w3.org/2022/10/11-dxwg-minutes.html PWinstanley
