Meeting minutes
Minutes Review
<kaz-brb> May-19
Sebastian: (adds roundtripping to agenda)
Publication
Sebastian: 1st of June is still on track for WD publication
… probably july for the CR
<mjk> (koster regrets, I have a conflicting meeting this morning)
McCool: testing will be focused on the WD version
<sebastian> https://
Sebastian: an issue was found in the jsonld specification
McCool: we need to workaround this in directories
Andrea: the only technology agnostic way of doing it would be by defining frames
… so it is hard to do it in a generic way
… kehio, another library of us, parses java models into rdf
… rdf is a graph and json is tree, so when you have cycles in json, you cannot tell where in rdf
… so it took me a couple of months but the Java library is open source
McCool: how do we validate extensions?
Daniel: victor has validation SHACL generated from ttl
McCool: that is for the core document
McCool: we need a way to get more information on the extension just by using its context
McCool: we should ask this the JSON-LD guys
<dape> s/dp: victor has validation shacl generated from ttl/dp: victor uses shacl shabe for generating the others
<cris> +1
Sebastian: so you want to put it in the context?
McCool: yes, maybe some context negotiation?
Andrea: so you want shacl in the context?
McCool: that or computing another url for finding the shacl
Sebastian: we can invite someone from json-ld group to a call?
McCool: an issue would be good
Sebastian: (writing issue in json-ld-api repository)
Cristiano: it is clear if there is a way to state or if there is a repository with the validation file
<sebastian> https://
JSON-LD and roundtrip
Sebastian: (created issue is https://
Sebastian: something more about this topic?
Modbus Binding
<kaz> wot-binding-templates PR 109 - Refining Modbus protocol binding
Cristiano: we discussed about how to map sub types of integers in json schema
<McCool> s/shabe/shapes/
Andrea: you can use xsd: (something) to allow that
https://
cris look at this link :)
Andrea: @type is not the right place for this
Ege: json schema min/max or the new vocabulary extensions can be used
Cristiano: I see, that makes sense
<victor> ack
Victor: I agree with ege
Cristiano: I will check
Cristiano: I have a question about the ontology
… we are defining these ontology for mapping but we are not experts. How to be prefix independent
McCool: prefixes are sometimes cached
Andrea: for schema.org people find it too long and use other prefixes
… it is not a good idea to rely on the prefix
Cristiano: so also we have the idea to have an ontology for the protocol and another document for how to use it in wot
Cristiano: also another ontology about binding would be nice
Victor: but that is already in the TD ?
<victor> SHACL
Sebastian: another annoying point is the byte sequence
Cristiano: yes I have seen that for the first time
Sebastian: Now I want to move the work to work on some PRs
McCool: it is difficult to refer to data schema for properties
… it complicates canonicalizationn
<kaz> wot-thing-description PR 1130 - Update AdditionalExpectedResponses with named data schemas
Victor: canonical form should be direct serialization of the information model?
McCool: yes
… I have to update my PR
Victor: this should be moved to section 6?
Ege: why not use $ref and then allow referring to schemaDefinitions
McCool: why not creating an example about it?
Sebastian: then let's merge this and vc and ege will work on the proposal
PR 1129
<kaz> PR 1129 - More fixes to canonicalization
Daniel: but you should not care about such details in canonicalization
PR 1151
McCool: now I want to talk about signatures
<kaz> PR 1151 - WIP: TD Signatures
McCool: I think we should use xml signatures
McCool: this signature is based on .XML Signature
McCool: this is not done yet
McCool: I don´t have all the keys yet
Cristiano: why is sparql there, you are working with JSON?
McCool: sure, I can get rid of sparql
Sebastian: is the signature part also signed?
McCool: it is added only at the end
Sebastian: thank you very much for your work mm
Sebastian: adjourned
