Agenda

McCool: Today's main topic is preparation for the TPAC meeting.

Farshid: can we look at some the PRs?

McCool: yes fine
… during the f2f right?

Farshid: I was asking for today

PR

PR 223

<kaz> Add object types to actions #223

McCool: seems fine, any objections?

Farshid: it is just about a TD, no ambiguity

McCool: 223 is an improvement, let's merge it

PR 225

<kaz> Add list of directory implementations #225

Farshid: it adds the 3 implementations

McCool: good news, now we have two SPARQL implementations
… good enough to approve the spec
… any objections?

PR 226

<kaz> Add assertion list and extract script #226

Toumura: added assertion list script

McCool: seems good
… minor change not testable with Assertion Tester to not automatically testable. Plus find which tests maybe automatically tested

Farshid: wemight need to transform the script to a github action

Cristiano: +1

McCool: let's merge it as is and open an issue to keep track of this feature

<kaz> newly created issue - Automate assertion extraction #227

F2F slides

<kaz> F2F wiki

McCool: F2F is tomorrow

mc shows the current agenda for f2f

McCool: we need a list of what is new
… review the state of implementation
… we need to label issues that needs to be closed before CR

Farshid: I think mqtt should be post-pone

Andrea: geospatial queries are deferred?

McCool: yeah we have early tests, but we lack alignments with other standards (i.e. OGC)
… we can add it as an experimental extension.
… OGC is still a working progress

Andrea: maybe add just a note about the possibility of doing geo-spatial queries
… if supported

McCool: about non-HTTP protocols CoAP is kind of special. .well-known might be supported out-of-box. But I am not sure to include it in this spec right now.

Christian: query live values?

McCool: we are not storing TM
… to support live values we need Timeseries
… is connected to Geospatial queries, cause location is dynamic
… I agree it is a future problem
… same as Shadows/Proxies

Farshid: error types?
… but maybe we can tackle them in this charter

McCool: we are already aligned with a well-know error format.

mc goes on issues labelling which one should be discussed during F2F

<kaz> related issue - Reconsider @type ThingID #190

McCool: to be discussed in the f2f
… event payload filtering deferred

<kaz> another related issue - Don't try to describe the Directory Service API in a Thing Description #172

McCool: propose closing issue 172

Remaining Issues

<kaz> Event payload filtering #176

<kaz> JSONPath and XPath response data models #156

McCool: we collected a good amount of issues to be discussed
