Re: GSOC idea: json api for plone

As said: json-ld is great, but it does not solve the problem of a 
Crud-Api. Who needs Linked Data compared to those in need of a JSON-CRUD 
API? I'd say latter has a majority.

There've been efforts to make plone.api available as a json api
https://github.com/xiru/plone.api.json/network

Also theres https://github.com/collective/collective.jsonify around an 
maybe more.

IMO it would be a good start to make all plone.api calls available as 
json-rpc. Also (with some level of abstraction on serialization/ 
deserialization) then it is easy to get at the same time an xmlrpc api.

The task to build a json-rpc plone.api is easy to understand and 
straight forward, so even for a Plone beginner doable.

plone.api.json is probably a good starting point - except it uses grok 
and does not check security (as far as i can see).

Then it can be extended to modify the content-objects in Plone itself 
and do what elose is needed in daily business.
