PR 107

https://github.com/w3c/wot-discovery/pull/107 - Update SPARQL DDoS ed note

Kaz: will wait for McCool to address Andrea's concern

Issue 98

https://github.com/w3c/wot-discovery/issues/98 - Need information model for directory

Farshid: we suppose to confirm which proposal is more preferable

Farshid: some people have already voted

Cristiano: what information will be included? Will it be standardized?

Farshid: it will be just registration data. We can decide later if this will be mandatory.

Andrea: can we extend the model to include metadata for filtering items?

Farshid: we have the type for "Directory" but not yet added to TD context. See https://github.com/w3c/wot-discovery/issues/54

Cristiano: it may be better to define a separate context for TDD instead of adding the class or other vocab to TD's context

Kaz: Farshid, can you generate a PR for this?

Farshid: would like to think about Issue 34 on links as well

Issue 34

<kaz> Issue 34 - Add links section to directory information model

Farshid: need to pick an appropriate relation type

Farshid: e.g., describedby from https://www.iana.org/assignments/link-relations/link-relations.xhtml

Koster: we could pick a registered type, e.g., describedby

Koster: i think there is a type for collections which may be a good option

Kaz: if we define this, we need to make sure other processors understand it

Farshid: will create a PR including the link and TD models inside TDD. Will use describedby relation type instead of furtherExploration as it is registered.

<cris_> +1 for Koster's proposal. collection rel type fits well in my opinion

Koster: allowing multiple relation types is a good idea and very useful in directories. It also relieves us from the burden of trying to choose one.

Kaz: I agree.

Kaz: we can go with describedby and then look into alternatives such as "collection" and "item" based on some concrete use case and flow.

Koster: describedby is intended for pointing to another resource, describing a resource through certain mean. It could even be pointing to some openapi spec.

Farshid: we can combine it with the content type to specify how the resource is described.

Koster: I agree, the generic describedby relation type can be used appropriately in different use cases.

Issue 104

<kaz> Issue 104 - Canonicalization requirements for directories

Andrea: we don't have an appropriate framing document. Have reached out to Sebastian and he is looking into it.

Cristiano: have you tried to implement anything to address framing?

<kaz> Andrea's updated comments

Andrea: i am experimenting. I have tried a JSON-LD 1.1 library and got some input from the maintainers of that library.

Andrea: the problem is not the conversion, but the lack of the frame to do it.

Kaz: maybe talking with the DID-WG guys would be helpful given the JSON-LD WG is in a maintenance mode.

Kaz: let's continue the discussion during the next Discovery call and also possibly during the TD call.
