## Topics

### Round Table

#### Angelo

- Preparing Solid Symposium talk.

#### Tim

- Had a call with Dan Brickley (and someone else?) about direction with schema.org, it would be good to have a meeting with them. Also discussed climate change and how to do something related to that. And also add (or updated?) "research organization".
- Gitter to Matrix: testing threads, and testing being able to see archives.

#### Alain
- rdflib and JSON-LD (invalid JSON-LD errors are silenced)
- latest rdflib is not building with solid-ui, returns a lot of errors, putting a link to issue in chat [#528](https://github.com/SolidOS/solid-ui/issues/528).

#### Jon

- Had an online meetup where Jon & Chase gave some presentations about: [starting.place](https://starting.place), a site for the Minneapolis meetup to coordinate learning and working on Solid; and SolidOS/Open source.

#### Noel
- Working on Umai app maintenance (only [print to PDF](https://github.com/NoelDeMartin/umai/issues/5) left).
- An update about urls of Solid Apps. I realized I was wrong about modern frameworks routing, they always reuse the page component (it doesn't matter if the route or the query parameter changes). May open a post in forum and discuss it there.
- Question for Tim, and also Dan from schema.org. What about http vs https? Will follow up in the chat.

#### Rahul
- not much solid-related, working on http headers and security headers

#### Maurits

- working on an app related to skills management
- question about combining ontologies
- using resumerdf ontology, is it a smart idea to use it, or should he search for a different one
- Tim: you can definitely mix different ontologies; it's good to use schema.org, also look at the ones the community is using, we have several favorites; related to resume, look at your solidos code for updating your CV; we're currently working on a standard for the rdf shape for skills; about using older ontologies--ask around on solid chat, also I wrote a blog somewhere on the solidos site about decision process for using ontologies
- Maurits: will take a look at the CV, it looks very promising, and will follow up next week or week after maybe
- question for angelo about solid symposium?
- Resources mentioned:
  - Bag of Chips: [Text](https://www.w3.org/DesignIssues/many_ontologies/BagOfChips.html), [Video](https://www.youtube.com/watch?v=ga1aSJXCFe0)

  - [Building Solid Apps which use Public Data](https://solidos.solidcommunity.net/public/2021/BuildingSolidAppsUsingPublicData-V3.html)

### Technical topics

#### rdflib / solid-ui build issues

- question: do we try to resolve problem (discussed above, 528 in solid-ui), or reverse the commit? The tests are failing.
- Tim: this is a common issue we have (failing tests). What's the error message? 
- Alain: no new tests have been added for it. re: error mesg, it is "...cannot read property ... of undefined"
- Angelo: does it try to fetch wikidata in the tests?
- Tim: it shouldn't.
- Angelo: seeing error related to fetching wikidata, and others; looking at branch, ahead of main; the error is from rdflib?
- Alain: yes, it's coming from rdflib, which was updated recently. the branch is "apply-patch" (spelling?)
- angelo: if rdflib is doing the fetch request, then the problem may be there --- but rdflib is mocked... what changed in rdflib?
- Alain: put the link to the rdflib commit in gitter chat (1732) (PR 574)
- Angelo: [looking at the commit](https://github.com/linkeddata/rdflib.js/commit/f94953b5e307f808fa3f437cb372b95d31dc638b) what do these changes mean: using insert instead of patch, some changes related to insert and delete, and some other changes?
- Alain: the problem, when I try to run node solid server with these changes, I didn't see a problem related to profile
- Angelo: I can reproduce the error locally.
- Alain: something about the auto-complete field tests.

#### Chat impersonation

- Alain: it would be interesting if we could all comment about [issue 90](https://github.com/SolidOS/chat-pane/issues/90) in chat-pane--about using private/public key to sign things
- Tim: is that unrelated? that is for signing a proof. everything in matrix is signed. B/c the things we're adding are simple, it shouldn't be a problem, 
- Alain: it could be re-used (for solid chat)
- Noel: if we allow deleting mesg's, anyone could remove mesg's; not sure which of the two is better
- Tim: could make it so if you really want to remove, you have to ask, and only the moderator could do it
- Noel: maybe a good idea, have it append only, and moderators could delete only, maybe a good compromise
- Tim: agree
- Alain: question about deleting mesgs
- Noel: You can edit or soft-delete, but the history will still be there; we could make it so user can soft-delete, and mods can delete for real . . . looks like it's time for mtg to wrap up
- Angelo: Just following up with Alain, just spend some time trying to debug those error mesgs and we can follow up later
