Next discovery meetings

McCool: next meetings in June may need to be cancelled due to conflicts with T2TRG, plugfest, F2F
... should we keep those meetings to work toward preparations for plugfest and F2F?
... next week (June 8) should be canceled. The week after (June 15) will be used for F2F presentation finalizations

Kaz: conflict on June 15th

McCool: shift the plugfest preparation call to an hour earlier and have the Discovery call at this time, such that kaz could also attend.

McCool: will wait for feedback from a larger audience for resolution on discovery design decisions.

F2F planning

McCool: no open PRs

Design document

<kaz> Design document draft

McCool: going through different points
... to be JSON-LD compliant, we should inserted the global context even to partial documents.
... the directory entry object containing the TD and other directory related metadata needs a context

Andrea: Is pagination mandatory? SPARQL doesn't support pagination.

McCool: pagination reduces the load on the client. It should be provided.

Cristiano: sparql supports offset and limit, which can be used for pagination.
... it is also very important to reduce the server load.

McCool: partial results: query mechanisms such as jsonpath naturally support return of partial results.
... for JSON-LD, the context must be added to TD fragments.
... discussing minimum (recommended) authentication/authorization requirements.

McCool: among basic, digest, jwt token, oauth2, the token based schemes provide scope better protection and also scope-based access control
... discovery API described in a TD

Andrea: can we use SPARQL to discover directories? Can one directory point to another?
... can one directory point to all other directories? is this scalable?

McCool: updated document: https://github.com/w3c/wot-discovery/blob/master/design.md

Closing

McCool: please create issues for other topics to discuss further
... provide feedback on existing issues e.g. TD signing, pagination, partial TD, query and filtering, etc

McCool: Note: June 15 discovery meeting will be during the regular time. Plugfest preperation meeting will be one hour earlier.
