Darko: Matthias is not available today and asked me to chair the call today

Hydra and Thing Description

Darko: is Bergi on the call?

(Bergi is not on the call)

<victor> https://github.com/bergos/wot-examples/

<inserted> scribenick: kaz

victor: Hydra examples above
... also goes through the Current Practices document

-> http://w3c.github.io/wot/current-practices/wot-practices.html#td-examples Current Practices document

victor: Bergi defines events

<Yongjing> who's speaking now? i see Darko?

victor: GET, PUT, DELETE operations

<Yongjing> Why the WebEx shows Darko_Anicic?

victor: temperature sensor

<Yongjing> see, that's my problem...

victor: Hydra middleware recognizes any Hydra-based APIs

darko: not clear
... how to interact with events?

victor: he defines 3 other examples

<inserted> scribenick: Yongjing

darko: take temperature as example to explain?

<inserted> scribenick: kaz

victor: (goes through the Hydra:supportedProperty examples)
... classes and Hydra properties

<inserted> scribenick: Yongjing

Daniel: missing aspects of protocols

victor: Hydra can map to abstract operations, e.g. GET, PUT

<inserted> scribenick: kaz

victor: mapping on protocols is quite obvious

<Yongjing> Daniel: need certain middleware?

michael: Hydra exposes underlying REST-based mechanism
... Thing Description is a template

victor: serializable as RDF

michael: RDF is just one possible notation

<inserted> scribenick: Yongjing

victor: to get the temperature in Hydra, need to address resource, with serialized media type

<inserted> scribenick: kaz

victor: the Hydra client doesn't have to understand the media type

michael: we could have Hydra Thing Description like our Thing Description
... I should join the discussion

victor: lacking modeling type system
... link or actual resource

<inserted> scribenick: Yongjing

victor: resource should only have properties as literal or links to the resources

Michael: will take closer look into Hydra and have further discussion

<inserted> scribenick: kaz

darko: if we have one description for temperature in one file
... and another file
... this would be definitely a hyperlink approach

victor: you can define classes
... and all the temperature sensors will refer to the class definition
... currently discussion on lifecycle
... interesting approach regarding this
... TD template
... if you recognize of URI of the class definition

michael: not only Thing Description for Hydra but some ontology for Hydra could be defined

<inserted> scribenick: Yongjing

michael: we can still use external ontologies

<inserted> scribenick: kaz

michael: interesting question on modeling ontology for Hydra

victor: everything should be Hydra class
... if you want further semantic definition, you can include Hydra class definition

michael: it has elegance to define everything within Hydra framework

victor: even for abstract concept
... to me it's not flexible enough from semantic viewpoint

<inserted> scribenick: Yongjing

victor: it means every concept would be de-referencable, including abstraction concepts, that's not flexible

<kaz> Victor's pull request

<inserted> scribenick: kaz

victor: my pull request above
... just a proposal

johannes: would suggest to merge this in unless any objections

darko: breakout session during the next f2f?
... you can raise a proposal

victor: is Matthias available by the end of this week?

johannes: would ask the group about if it's OK to merge this proposal

(no objection)

yongjing: question about gh-pages branch

RESOLUTION: #299 can be merged, status remains as proposal to be discussed on TPAC

johannes: automatically available as a rendered HTML at some URL

darko: Kaz will check with Dave and other W3C Team
