I want to be able to create a Universe whose source is RESTful Webservice, and data in that Webservice was coded using JSON. In response to my question on old SAP SCN blog, people asked me to try the blog Creating a Universe on top of a Webservice, which didn't help. Because, that blog is talking about WSDL webservice as the source, for which we get the driver already, and that doesn't help me.
I wanted to ask if SAP provides a connector/driver to the RESTful Webservice whose data was coded using JSON? If not, has someone created their own connector? If yes, I can try to recreate it, I don't know Java SDK, but can try to get SOME (not a lot) of help, if needed.
Create a Custom Data Source plug-in (must be built with Java SDK, and creates a source for WRC only; that is, it's not a universe)
Create an intermediate web application that would retrieve the source data in JSON and covert it to XML, which can then be used as a source for the universe
Use a jdbc driver that connects to the RESTful source. The universe then connects via jdbc. A quick Google search produced this commercial product: http://www.cdata.com/drivers/json/jdbc/. I don't know any more about it, or if there are non-commercial alternatives available
