I know we can microblog (ublog) to a community by sending JSON to this endpoint:
https://CONNECTIONSHOST/connections/opensocial/rest/**ublog**/urn:lsid:lconn.ibm.com:communities.community:cbcdf38a-8526-4610-a83a-9ed6744de6be/@all
We can also post JSON that contains embedded experience to the activitystream using this endpoint:
https://CONNECTIONSHOST/connections/opensocial/xxx/rest/**activitystreams**/@me/@all/@all
The documentation (http://www-10.lotus.com/ldd/appdevwiki.nsf/xpDocViewer.xsp?lookupName=IBM+Connections+4.5+API+Documentation#action=openDocument&res_title=Community_specific_feeds_ic45&content=pdcontent ) suggests that you can specify a community for the activitystream service, but when I post the embedded experience JSON to this endpoint:
https://CONNECTIONSHOST/connections/opensocial/xxx/rest/**activitystreams**/urn:lsid:lconn.ibm.com:communities.community:cbcdf38a-8526-4610-a83a-9ed6744de6be/@me/@all
Than the update is just posted to the homepage (main activity stream).
When I post the embedded experience JSON to the ublog service, the embedded experience is not displayed just the basic content.
The question is how can I share an embedded experience with just the community ?
