Victor: slides about aligning ssn/sosa with TD vocabulary
... proposal for an alignment to align td: Thing with Feature
of Interest

Victor: there are two alignments
Mlefranc: wot:Property and ssn:Property does not align very
well
... wot:Property should better be aligned with ssn:Procedure
<MariaPoveda> I'm looking at this schema for the td ontology
<MariaPoveda>

Victor: I defined td:Property as sub-class of
ssn:ObservableProperty and there are no concences about this in
WoT group

ml#td-context-extension
[11] http://w3c.github.io/wot/current-practices/wot-practices.html#td-context-extension
Mlefranc: InteractionPattern in wot ontology is aligned to
ssn:Procedure, therefore td:Property should also be assinged to
ssn:Procedure
Victor: td:Property should be aligned to Saref:Property.
mlefranc: in ssn a System implements one or more procedures, in
td a device implements some interaction pattern such as
td:Property, td: Event or td:Action to get data about a device
Victor: there is relation between input and output data in SSN
... is there a relation for instance between ssn:Observation
and output data
mlefranc: There no such relation in SSN. the floor is
completely open for creativity there

Victor: how inputs and outputs are used in ssn ontology
<mlefranc> [15]https://w3id.org/rdfp/
[15] https://w3id.org/rdfp/
Darko: i find it important to reach some consenses on mapping
between td ontology and ssn ontology
... ask mlefranc to prepare some slides about td and ssn
mapping
... we would like to use ssn in iot.schema.org, therefore it
would be nice to have mapping
... discussion about the mapping could be discussed on mailing
lists
mlefranc: important point missing is duplicating td:Property
and aligning one to ssn:Property and one to saref:Property
Victor: I am not sure if we should create our own ssn:Property
in td.
<mjkoster> I'm not comfortable that we have reached a
conclusion about what action to take
Victor: no need to duplicate the terms from ssn
<DarkoAnicic> ACTION: mlefranc to add his proposal on the
mapping between TD-Ontology and SSN to Git:
[16]https://github.com/danicic/wot/blob/master/linked-data/link
ed-data-vocabularies.md [recorded in

[17] http://www.w3.org/2017/08/18-wot-minutes.html#action01]
<trackbot> Created ACTION-115 - Add his proposal on the mapping
between td-ontology and ssn to git:
[18]https://github.com/danicic/wot/blob/master/linked-data/link
ed-data-vocabularies.md [on Maxime Lefrançois - due
2017-08-25].
[18] https://github.com/danicic/wot/blob/master/linked-data/linked-data-vocabularies.md
Darko: concludes that we started the discussion on mapping with
ssn and we will continue discussion
Victor: ask Maria about alignment between core onology in
vincinity ontology and ssn.
Maria: ssn:Property is used in a little different way. I can
explain about it. I can propose the architecture for td case as
an example.
Victor: propose Maria and Maxim could present slides about
alignment in the same call
Darko: asks DanhLePhuoc, if could organize the next telco
... Maria and Maxim could present slides in the next meeting.
