Activity streams standard: ​http://activitystrea.ms/

Super branch where the feature was initially developed (this has now been merged into master): ​https://github.com/okfn/ckan/tree/feature-1515-activity-streams

Etherpad: ​http://ckan.okfnpad.org/notifications (most relevant parts inlined here)

Friedrich's mockup: ​http://datahub.pudo.org/pudo
