Subject Re: V2 REST Api documentation (first-cut)
Date Wed, 01 Mar 2017 14:54:02 GMT
Hi Apoorv,
You are welcome. I think this is very important work you are doing to 
making the documentation clear and complete, will make it easier for new 
developers to get involved with Atlas. On your responses :

1) Great
2) Great
3) Does this mean admin requests will not be documented. I would suggest 
we need to document all APIs.
4) OK I have not played with these
5) Great
6) Great. 

Something else I notice: I would have expected a PUT request for entity 
updates, as there was in the V1 API; as per the usual http verb 
definitions. Using POST for updates is not what I expected. 
  all the best, David.

Thanks for your detailed review David. 

1. I see that there’s some inconsistency in the Javadocs for EntityREST 
fixing those should fix the docs too.
2. Will update the javadocs for the *def classes too. Class -> datatype in 
3. I didn’t add any admin requests as I feel they’re meant for ops rather 
that devs.
4. CRUD of enums and ObjectId is not exposed as separate API thus the docs 
don’t have any specific section for the same. The API doc examples have 
sample JSON for *def objects. Let me know if anything is missing there.
5. Will update the javadocs for all the classes in the model package for 
better description.
6. v2/entity/uniqueAttribute/type/{typeName} is a GET for entity so it’s 
under a correct REST resource.
