How to GET the RelationTypes using REST API.

0
Ashutosh Chaturvedi (11●2●2) | asked Jan 31 '13, 5:50 a.m.
In my application I need to get the available relation types to relate an asset to the already existing one in RAM using relations like Parent, Dependent, ...etc.
As for communities I performed GET operation on "....../ram/oslc/communities", and getting the result
so by the using same idea I am performing a GET operation on "....../ram/oslc/relationshipTypes", but getting no result.

Is there any other way to get the desired result.

Mostly, these are internal APIs (on the <server>/ram/internal path vs. the oslc one). There is no service to find all the relationships in the repository at this time.  I opened Need a Rest API to list existing relationshipType in the repository (79692)

 It's not public API, but you can get a JSON representation of the relationships from
http://<server>/ram/internal/service/RelationshipService.getRelationshipTypes

Hi Sheehan,
Thanks for the comment, it works, but we need to get the result in xml format.
The headers I am using are: 1. "Authorization: Basic q2hhdHVydkE...."
                                               2. "Accept: application/xml"
I also tried "Accept: application/rdf+xml"
but the format(I think it's a JSON format) I am getting is not the desired one.....
Is there anything I am missing here?
Please comment....

As Sheehan said, the internal form only produces JSON. It is used internally by RAM for the browser support and the browser handles JSON faster than XML. Since it wasn't meant to be an API there wasn't any effort to produce an XML format.

That is what Gili's enhancement is for, to produce the different formats through the more formal REST calls.
