PRs and Issues

PR 241

https://github.com/w3c/wot-discovery/pull/241

-> terminology will only be defined in the architecture document to avoid duplicates

Merged

PR 243

https://github.com/w3c/wot-discovery/pull/243

Some formatting and wording still to be fixed.

PR 244

https://github.com/w3c/wot-discovery/pull/244

Challenge: How to recommend one search API if only one is specified?

"at least one" -> "a"

Kaz: it would be better to use "SHOULD" instead of "RECOMMENDED" because we usually use "SHOULD"

McCool: right. Farshid, can you fix that?

Farshid: in that case would be better to use "MAY" instead of "OPTIONAL".

McCool: yeah

XPath -> XPath 3.1

SPARQL -> SPARQL 1.1

McCool: SPARQL expression -> (URL) encoded SPARQL expression

Farshid: similar for JSONpath and Xpath

SPARQL update queries out of scope -> SPARQL update queries have to be disallowed

Farshid: SPARQL update queries MUST NOT be supported

Check for correct http response code: 403 (forbidden)?

Will be own issue, not part of this PR

Issues

Issue 216

<kaz> Issue 216: Define role of "Discoverer/Registerer"

<kaz> WoT Architecture 1.1 draft: 3. Terminology

<FarshidT> Discoverer: An entity that generates and registers a TD with an exploration service on behalf of a Thing which may not be able to do it for itself.

Christian: just checked with Apache Jena and update on the /query endpoint results in http 400 (bad request)

See comments in issue

Farshid: definitions do not sound straightforward

McCool: maybe "generator" which produces and stores TD
