[Fiware-ngsi] JSON

[fano.ramparany at orange.com]

Hi,

In the context of the development of the semantic extension of the the PubSub GE semantic, we are developing a NGSI/XML to RDF/XML translator. To start with we are focusing on the NGSI/XML queryContextResponse...xml messages related to geolocation. We plan to use the "attributeDomainName" element as an hint to identify a geolocation context information.

We have a first question about this: is there a reason for introducing 2 different values of this element related to geolocation? Namely: parcelGeo, geolocation? Why don't we simply use geolocation?

More generally, could we assume that the value of the "attributeDomainName" could be used as a way to anticipate what the "contextAttribute" names (in the "contextAttributeList") will be?

If it is the case, we can use this element to identify which ontology the target rdf will comply to and to use the corresponding "contextAttribute"s names as properties of the ontology or to find in an existing ontology the mapping between the properties of this ontology and the "contextAttribute" names.

Apart from geolocation, in the examples we have found messages tagged with "parcelStep" "attribute DomainName". We assume that we should elaborate the corresponding RDF in compliance with some supply chain ontology. 

It would be interesting to do this translation exercise, with more NGSI/XML examples coming from UC projects which are using the PubSub GE, although the policy we currently foresee is that each UC project define its domain ontologies and we supply the project with a method to automate the transformation of the NGSI/XML content into RDF complying to this domain ontology.

Any feedback on this is more than welcome,

Thanks,

Fano

Hi,

We have a bunch of XML examples for our NGSI binding at
https://forge.fi-ware.eu/scmrepos/svn/iot/trunk/schemes/xml_examples/
but, what about JSON? Is there any similar bunch of example available in
some place, please?

Thanks!

Best regards,
