[Fiware-ngsi] GET for context Attribute

[Tobias Jacobs]

Hi Denes,

My understanding was that we introduce the "ContextAttributeReponse" in analogy with the existing "ContextElementResponse".  This structure is used several times in the binding.

I mean you meant
<queryContextAttributeResponse>
<contextAttributeList>
                                <contextAttribute>
....
                                </contextAttribute>
<contextAttribute>
....
                                </contextAttribute>
                </contextAttributeList>
                <statusCode>
                                ....
                </statusCode>
</queryContextAttributeResponse>

OK, I update the XmlSchema and also the example queryConytexAttributeReponse with the new version.

Example:

<contextAttributeResponse>
                <contextAttributeList>
                                <contextAttribute>
....
                                </contextAttribute>
<contextAttribute>
....
                                </contextAttribute>
                </contextAttributeList>
                <statusCode>
                                ....
                </statusCode>
</contextAttributeResponse>

BR,

No problem, simply that I implemented using a
QueryContextAttributeResponse structure with
ContextResponseList consisting of ContextElementResponse elements.
And a Statuscode typed ErrorCode field.

Can you update the doc then? Also Salvatore, can you modify the test xsd?

Best,
Dénes

Hi Denes,

There was as inconsistency between the binding document and the xsd. In the xsd a ContextAttributeResponse only contained a single attribute
(see the email sent by Fabian last week's Wednesday).

I changed the binding document accordingly, but I think that you are right, the ContextAttributeResponse should contain a list of attributes (as there might be multiple value instances), so I should rather have changed the xsd.

If you agree with that view, I am happy correct this error.

Sorry for the trouble!
Tobias

Hi Tobias,

There seems to be a huge error int he NGSI-10 document!

The GET at Attribute of individual context entity returns only a single ContextAttribute!

It supposed to return a queryContextAttributeResponse, with a contextAttributeList!!

Can you check who edited this out of the document? Currently this is simply wrong!

Best,

Dénes
