Have a look at bundles/activity/api and bundles/activity/impl. In OAE 1.4.0 most activity creation goes through ActivityUtils.postActivity() and trickles down to ActivityServiceImpl via several layers of events that make creation asynchronous. (And hard to debug.)
Activities are posted from server side code when content is created, modified, commented on, and several other cases. The UI also creates some activities directly using the Activity Create Servlet. Activities attach to the node on which they occur -- eg if I comment on piece of content /p/abcdef then I can find its activities by getting /p/abcdef/activityFeed.tidy.infinity.json. When an activity is posted it is "delivered" to all the user's contacts who have permission to read the source node. Delivery happens by writing the sakai:routes property to Solr. /var/search/activity/all.json is the feed of all activities that are public (for anonymous uses) or public/shared to everyone (for logged-in users). In 1.5.0 there will be more types of activities posted from server-side code. There will also be a cleaned up API and less asynchrony in activity creation. There will also be more feeds like all.json that deliver activities just for a particular user, or for a particular content item, or for a world. -chris On 7/25/12 10:54 PM, Qi Feng wrote: > Hi, > > I am trying to figure out what kind of information sakai captures when > there is an activity, what kind of activity it captures, and also what > structure it uses to link those events.
