We have a Fusion CRM account, with Social Network as part of it.
Yes, it is possible to share a CRM object in OSN (as described in Implementing Oracle Social Network Integration - 11g Release 7 (11.1.7)), but we want to add more "automated" functions to it.
We might try calling it from CRM Groovy scripts, or maybe from an externally hosted application.
There seems to be assuggestion that OSN has a public RESTful API (see http://dgielis.blogspot.com.au/2012/10/integration-of-oracle-social-network.html), but I cannot find any referenced to such API.
Does it exists at all? Is there any documentation? Does any Web Services API exists?
We do provide an API for working with the Oracle Social Network to do custom development as you are describing. We make this documentation available to known customers, and I will be following up with you directly in the next day with the location you can retrieve it.
