Java API for Social Media
This document discusses the development of a Java API for accessing social networks. It provides background on existing technologies like OpenSocial, Shindig, and social networking APIs. It then introduces the Agorava project, which aims to create a standard Java API (Agorava) and reference implementation (Agorava Socializer) for social integration. The presentation concludes with a demo of the Agorava Socializer.

- 12. What’s said aboutOpenSocial • OpenSocial is what Google created for MySpace (Yammer CTO and co-founder Adam Pisoni) • Out of the box, most gadgets are publicly available content that do not require authentication and authorization. (ThoughtWorks Studios about OpemSocial gadgets) • OpenSocial is a specification that provides a standard way to share content between semi-trusted applications. • While initially proposed for public facing social networking sites, it has possibly more potential within the corporate firewall (ThoughtWorks Radar, March 2012) 13 © 2010-2012 Werner Keil, Antoine Sabot-Durand and Others

- 15. Facebooks’ Query Language • All of the Facebook API is basically a set of wrappers around their SQL like FQL query language. So you can, if you prefer, make custom methods out of FQL query strings. var myQuery='SELECT name FROM user WHERE uid='+api.get_session().uid; api.fql_query(myQuery, getFQLResponse); getFQLResponse() is a developer-written callback function If it’s SQL like, could we use something like JPA around it? 16 © 2010-2012 Werner Keil, Antoine Sabot-Durand and Others
- 16. DaliCore – History DaliCMS (2006): “Web 2.0 ready CMS” Open-source “CMS” with community features 2008: integration with Shindig, provides OpenSocial Implementation (JavaScript code from Shindig, Java code in DaliCMS) Developed as Glassfish incubator project 17 © 2010-2012 Werner Keil, Antoine Sabot-Durand and Others
- 17. DaliCore – CMS More than a CMS → DaliCore Adds functionality common to users, content and permissions on top of Java EE 6. Focus on Users and Permissions. In about every project that uses DaliCore, users should be able to login with existing credentials (Facebook, Twitter, Google Connect,...) Dali modules extend DaliCore
- 18. DaliCore – Connect public abstract class ExternalNetwork public abstract Response connect(String callback); public abstract ExternalToken callback(String requestToken, String verifier); public abstract OnlineAccount createOnlineAccount(ExternalToken accessToken) throws DaliCoreException; ExternalNetwork class is extended by FacebookExternalNetwork TwitterExternalNetwork GoogleExternalNetwork
- 19. DaliCore – Integrate The User concept in DaliCore can have 0 or more instances of “OnlineAccount” In projects created with DaliCore, the administrator/configurator decides what social networks are supported. Users can access all functionality using their social network credentials.
