Can we make social communications as simpleand universal as email ? Facebook MySpace  Friending and following whatever.com across networks  One identity and yet multiple communities  Data portability 360 Google

A lot of activities in this field... … but no such platform yet

XMPPWhy XMPP for Onesocialweb ?Web world is synchronous - send request - wait for answer - receive responseXMPP is asynchronous - long lived connections - event based messagingFrom: XMPP 101 by Peter Saint-Andre and Remko Tronco, FOSDEM 2009

XMPPWhy XMPP for Onesocialweb ?Only technology to achieve such a federation seamlessly: Identity (user@domain) Security (TLS and S2S with dialback) Discovery (XMPP Disco) Useful extensions (Roster, PubSub, …)Doing the same in the web world requires to assemble: OpenID (identity) Oauth (authentication and authorization) Webfinger (discovery and openid on en email) Pubsubhubbub (server to server push notifications) Salmon (messaging and commenting) … and to address a lot of other issues (e.g. Privacy, NAT clients)

Yet, no common way to describe rich socialinteractions... leading to proprietary data models title + link + summary + author + id + updated

Activitystreams provides a common language todescribe social interactions... actor verb object target

Activitystreams provides a common language todescribe social interactions... eschnou posted a note

Putting it all together

Evolving spec, but ...Already been adopted by:- Facebook- MySpace- Windows Live- Google Buzz- BBC- Opera- Superfeedr and many others...

Fine grained access control- Both public-oriented (Twitter-like) social nodes as well as private-oriented Facebook-like social nodes- For activities on a per activity basis- For profiles on a field per field basis- for relations, etc

Fine grained access control- Public<osw:acl-rule> <osw:acl-action permission="http://onesocialweb.org/spec/1.0/acl/permission/grant"> http://onesocialweb.org/spec/1.0/acl/action/view </osw:acl-action> <osw:acl-subject type="http://onesocialweb.org/spec/1.0/acl/subject/everyone"/> </osw:acl-rule>- Roster-groups<osw:acl-rule> <osw:acl-action permission="http://onesocialweb.org/spec/1.0/acl/permission/grant"> http://onesocialweb.org/spec/1.0/acl/action/view </osw:acl-action> <osw:acl-subject type="http://onesocialweb.org/spec/1.0/acl/subject/group"> Family </osw:acl-subject></osw:acl-rule>

XMPP on Mobile – OSW Android Client- Reference Implementation- Android provides background threads necessary for real-time notification- Understand connectivity issues when switching bearers or reconnecting (2G/3G/WIFI/No network)- Impact on battery life- Network traffic implications

Our implementationUsing some great open source libraries:- Smack library- Asmack library- JZLib library

How would you create a social shopping listapplication ?Create shopping listsShare them with friendsCollaborate on shopping itemsReceive real-time notifications e.g. Shopulator on Android

Today you need a lot more than a mobile appWe need a back-end … and a solution for pushserver... notifications User registration  Custom TCP sockets Social graph management  Web sockets (e.g. inviting friends)  Comet (HTTP Long polling) Data storage for the shopping list  SMS Web API  Apple Push Notifications (to communicate with the mobile client)  Android C2DM

With Onesocialweb, you focus on yourapplication and let the protocol do the restCreate a shopping list object and a user as a collaborator ShoppingList list = new ShoppingList(); list.setTitle(“BBQ on Sunday”); list.addItem(“bread”); list.addCollaborator(“alice@betavine.net”);

Federated Social Web & SWAT- Federated Social Web Summit, June 2010 in Portland- June 2011 in Berlin- SWAT- Social Web Acid Test

The SWAT0 Use Case1.With his phone, Dave takes a photo of Tantek and uploads it using a service2.Dave tags the photo with Tantek3.Tantek gets a notification on another service that hes been tagged in a photo4.Evan, who is subscribed to Dave, sees the photo on yet another service5.Evan comments on the photo6.David and Tantek receive notifications that Evan has commented on the photo

SWAT0 Assumptions- Dave, Tantek, and Evan have accounts on different social networks- These social networks have at least two different codebases

W3C Incubator Group- More SWAT-like test cases and challenges- Community-driven specifications- Ostatus and related protocols (PubSubHubbub, ActivityStreams, Salmon, Portable Contacts, and Webfinger)- Other architectures: SMOB and XMPP-based- Best practices for privacy and security for the federated social web.
