Activity Streams is an open format specification for activity stream protocols, which are used to syndicate activities taken in social web applications and services, similar to those in Facebook[1]'s, Instagram's and Twitter's.
The standard provides a general way to represent activities. For instance "Jack added Hawaii to his list places to visit". Would be represented as actor:jack, verb:add, object:hawaii, target:placestovisit.
Implementors of the activity Activity Streams draft include Gnip, Stream, Stream-Framework and Pump.io.
The largest open source library (based on watchers) is Stream Framework, the authors of Stream-Framework also run getstream.io. In addition there is a trend of SOA (service-oriented architecture) where third parties power this type of functionality.
