Minutes

<kaz> Nov-9

meeting starts reviewing the minutes from the previous call on Nov 9 and the vTPAC

first the ones from the 2020/11/09

<kaz> approved

<kaz> vTPAC minutes

syntactic search review from TPAC slides

McCool: we should clarify short applies both JSON Path and XPath
... ....put space between words connected with &
... ....any comments in the syntactic query session?

no comments in regards of syntactic search

<kaz> (fixed the typos)

Andrea: ....maybe the distributed search among TDDs was the most interesting part

McCool: ...federation could be an optional feature maybe

Andrea: ... but in the case of the TDDs I think the federation as it is is not as suitable as an ad-hoc discovery algorithm

mccool creates an issue for the further discussion on this topic

Farshid: are there two ways of federation?

McCool: we need to check the specification

all the issues and questions about this topic are included in the issue created

<FarshidT> https://github.com/w3c/wot-discovery/issues/34

Issue #97

issue link: https://github.com/w3c/wot-discovery/issues/97

mccool creates another issue with the necessity of having a model for the directory

this issue is directly related with the federation one

<FarshidT> https://github.com/w3c/wot-discovery/issues/30

link to the issue of the information module

https://github.com/w3c/wot-discovery/issues/98

<cris_> https://github.com/w3c/wot-discovery/issues/18

mccool is grouping a set of related issues under the issue number #98

McCool: ...another issue is how to summarize the information stored in a TDD registered in another semantic issue that could be interesting is the validation, should we use shapes?

McCool: ...maybe that is too much, we have Json schema

Cristiano: ...maybe we could have a semantic and a syntactic level of validation?

mccool creates a new issue to discuss this matter

link to the issue: https://github.com/w3c/wot-discovery/issues/99

<McCool> https://github.com/w3c/wot-discovery/issues/99

<kaz> kaz: maybe something more than what Playground does. so agree we should re-define validation for WoT Discovery

currently, LinkSmart is not using SPARQL

McCool: is somebody else working on another?

Andrea is working on one, and Cristiano also will work on that very likely

this finishes the TPAC meeting minutes review

<McCool> proposal: discovery sections of the TPAC 2020 minutes are now suitable for release

RESOLUTION: discovery sections of the TPAC 2020 minutes have been reviewed by the Discovery TF and are now suitable for release

Issues

<inserted> Issue 79

now the group reviews the issues

McCool: one issue is the dynamic injection of values into TDs

Andrea: I have a publication on that
... the link for the publication https://www.mdpi.com/1424-8220/20/3/822

several members from the Discovery TF agree that the dynamic injection should not be mandatory

<kaz> McCool's new comments

<McCool> https://github.com/w3c/wot-security/issues/196

McCool added a new security issue for Thing Model, do we want to have mandatory security requirements for TDD?

McCool: ...this could lead to DoS attacks
... ...we could mitigate this
... ..by rate limiting queries from an entity

Farshid: maybe we could have the mitigation apart from the implementation

McCool: we can write down the mitigation as pointers

this discussion is written down in issue #96

issue link: https://github.com/w3c/wot-discovery/issues/96

<McCool> https://github.com/w3c/wot-discovery/issues/86

meeting is finished
