Who has implemented OpenSocial ?
300 Million reach now
Containers provide a social context
OpenSocial separates application logic from social contextan app sees user ids - the container makes them peopleUsers understand the social contract of the containersSave apps and users from re-registration hell
Containers don’t choose users
Containers set up the social model, users choose to jointhey grow through homophily and affinityNetwork effect can bring unexpected userbases
OpenSocial gets you to all their users
You don't have to pick a site to specialise forYou get to spread through multiple friend groupsYou'll be surprised by where your users areso make sure you plan to localize
Not just Social Network Sites
Social network sites - Profiles and home pagesPersonal dashboardsSites based around a Social ObjectCorporate CRM systemsAny web site
How do we abstract these out?
Viewer + friendsOwner + friends
The Viewer and Viewer friends
Owner and Owner friends
Owner and Viewerare defined by Container
The Application gets IDs and connections to other IDs
the Owner need not be a PersonIt could be an organisation
or a social object
Kinds of container - Social network sites
Profile pagesOwner is profile page ownerViewer may not be known, may be owner or other member
Home pagesOwner is Viewer (must be logged in to see)
ExamplesMySpaceHi5Orkut
Kinds of container - Personal dashboard
like Home pagesOwner is Viewer (must be logged in to see)
Friends may not be definedExample:
iGoogle, My Yahoo
Kinds of container - Social Object site
Pages reflect the object - movie, picture, productOwner is the objectOwner friends are people connected to the object
may be authors or fansViewer is looking at it, Viewer friends are people you may want to share with
Example:Imeem is a bit like this - opportunity for sites like Flickr, YouTube
Kinds of container - CRM systems
Pages reflect the customer Owner is the customerOwner friends are people connected to the customer
may be your colleagues, or other customersViewer is you, Viewer friends are your colleagues or customers
Example:Oracle CRM, Salesforce
Kinds of container - Any web site
Owner is the site
Owner friends are site usersViewer is you,
Viewer friends are your friends who have visited this siteExample:
Google Friend Connect will enable this for any site
®friendster

Google Friend Connect
Personal Web sites (e.g.blogs) have readers, contacts, connections for a social graph
