[Fiware-ngsi] Comments on the NGSI-9 and NGSI-10 REST binding drafts

[Bisztray, Denes (NSN - HU/Budapest)]

Hi Ken,

Thanks for your extensive critisicm, lucky we are on the same train of thought, and thus most of your problems were already addressed. Comments inline:

>Now, it would be good if a developer could read these documents and have a completely clear picture on 
>what he/she needs to implement.

BD: The document was created in parallel with development. NSN has working code using Java/Jersey.

>Personally, I would have preferred to have all the information gathered in one single document.
>But that's just a matter of taste.

BD: It is a matter of copy and paste. If someone has the resources should feel free to do it.

>Another very useful thing would be to have a sample ContextProvider/ContextConsumer implemented, to 
>use during tests.
>Is there anything like that? I mean, a running executable.

BD: Yes, it was useful indeed. This is exactly how we tested our system. Currently it is running locally on my computer.

>Also, being able to connect to the IoT-Broker and Pub/Sub Broker would be very valuable during the 
>implementation/testing phase.
>Perhaps we could mount a 'test' IoT-Broker and Pub/Sub Broker ... ?

BD: Since the pub/sub broker is not available we could not do it. 


>   - is JSON not to be supported?

BD: in our current NSN implementation it is not. But since it was implemented using Jersey, it is pretty trivial to support it as well.

o 1.2.1
>   o An EntityId contains an Id-String and a Type

BD: I don't seem to understand the question. It is in XML, what is the exact problem?

>   o Typo: 'tyeName'
>   o Possible cut n' paste error:
>     'Context entity type' and 'Attribute container of entity type' has the exact same description ...

BD: thanks for pointing it out. However, this is in an SVN what you can freely edit. Feel free to correct these minor mistakes with track changes. 

>   - What are the 'scope types' and their possible values?

BD: I'm sorry, but this is extensively detailed in the NGSI context management official document. I would not want to go into detail in this email.
