Enterprise Social using Open Source Frameworks (SMWCPH)

1,752 views

Published on

A Social Media Week Copenhagen 2013 session. Following the path of projects like Seam Social, a number of people started to work on Agorava, a “reference implementation” for Social Network integration in Java.
In this session, you will see examples from a number of frameworks that help developers to integrate their projects with existing Social Networks, both Public (Facebook, Twitter, Google+, LinkedIn, Xing, Yammer,…) and Corporate, e.g. within the Enterprise or Institution (University, Hospital, Library, Museum or individual Artists…) It also aims to assist Java Enterprise technologies and frameworks by adding social media features to web sites or services developed using Java or running on a JVM.

This session is a hands-on presentation, showing live code examples where possible and appropriate.

  7. 7. Before JSR 357 (Java Social)7
  8. 8. Twitter4J • Twitter4J is an unofficial Java library for Twitter API. With Twitter4J, you can easily integrate your Java application with Twitter. • Its author, Yusuke Yamamoto used to work at Twitter. While he did, he was briefly meant to represent Twitter in the Social JSR EG. • It’s light and based on Java 1.4 to be integrated in mobile app for instance8
  9. 9. Scribe Java • Scribe is Java framework that provides basic OAuth function • It also contains configuration for a lot of Social Media • Only one dependency on Apache Common Codec • At the heart of Agorava 0.59
  10. 10. 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 DaliCore project, users should be able to login with existing credentials (Facebook, Twitter, Google Connect,...) • Dali modules extend DaliCore10
  11. 11. Spring Social • Spring social that inspired Seam Social and Agorava and has been around a bit longer • Spring Social module were used to create first Agorava modules (thanks to OSS and ASL2) • But it’s Spring only module....11
  12. 12. Along came JSR 357 • In march 2012 on Werner Keil’s initiative, Java Social was submitted to the JCP to become a JSR • It proposed to standardize high level access to Social Media for the Java Platform • It was voted down by 8 votes against 512 Images © 2003 Universal Pictures.

  13. 13. What went Wrong?(Feedback from vote)13
  14. 14. Too Broad ? Maybe...14
  15. 15. Too Soon? Lack of real POC...15
  16. 16. It can’t be standardized? FALSE16
  17. 17. Standard part in Social Media • All social medias use REST as transmission protocol • Most of them transmit data in JSON format and some in XML • Identification & Authentication are almost entirely based on OAuth protocol17
  18. 18. REST • REpresentational State Transfer : Requests about resource representation (customer, book, order) • REST is based on low level HTTP concepts • Each resource has a unique identifier (an URI). 4 HTTP verbs can be applied to a URI : GET, POST, PUT, DELETE • Java has a standard for REST: JAX-RS. Version 1.0 doesn’t provide client API yet. JAX-RS 2.0 will18 provide one
  19. 19. JSON • JavaScript Object Notation: 1: { 2: 3: "firstName": "John", "lastName" : "Smith", Data format inspired by 4: "age" : 25, 5: 6: "address" : { JavaScript. It became a 7: "streetAddress": "21 2nd Street", 8: 9: "city" "state" : "New York", : "NY", standard for online services10: "postalCode" : "10021"11:12: }, "phoneNumber": including Social Media.13: [14: {15: "type" : "home",16: "number": "212 555-1234"17: },18: {19: "type" : "fax",20: "number": "646 555-4567"21: }22: ]23: }19
  20. 20. OAuth • OAuth is a protocol to delegate rights for an application to act on the behalf of an user who granted its rights without giving away login / password • Developed by Twitter, Magnolia and Google, it was made standard by IETF in April 2010 under RFC 5849 • Version 2.0, simpler to use but often criticized for too many implementation was standardized in October 2012 under RFC 6749 and 6750. It’s already used by many actors (Facebook, Google, Microsoft)20
  21. 21. OAuth (2) • All Social Media services are based on OAuth 1.0a or 2.0. • To use OAuth, one has to create an application on the targeted service to have an entry point for consumer21
  22. 22. OAuth has 3 steps • Creating an application in an OAuth Social Media service • Initialization: the right granting phase also called the OAuth Dance. At the end of the dance we obtain an access token (formed by a public and secret part) to use in the next step • Signature: each request is signed with an access token identifying the OAuth application that’s been granted rights22 Images © 2003 Universal Pictures.

  24. 24. OpenSocial • Become an OpenSocial Container Get Shindig (PHP or Java) or the Google implementations* • http://shindig.apache.org OpenSocial Container • Look at examples & documentation • http://code.google.com/p/opensocial-resources/wiki/SampleApps • * See later why24
  25. 25. OpenSocial – Shindig • Open source implementation of OpenSocial & Gadgets specification • An Apache Software project • Available in Java & PHP • http://shindig.apache.org It’s Goal: “Shindigs goal was to allow new sites to starthosting social apps in under an hours worth of work“• Those who tried it confirm, this failed quite miserably 2525
  26. 26. OpenSocial – What is a Gadget? Simple gadgets for getting a Grid proxy credential and running remote commands. Both run on my own Web server.26
  27. 27. OpenSocial Fork• Death Star The “official” OpenSocial implementation has shifted – from Shindig to Google Code https://code.google.com/p/opensocial- resources/ And just plans to move yet again, this time to GitHub! In fact, Google’s OpenSocial Ruby Gem moved there 4 years ago, and the code hasn’t changed since https://github.com/revans/opensocial (original Google Code SVN by MySpace also still exists;-)27
  28. 28. Who uses OpenSocial?• OpenSocial Empire • MySpace • Orkut • Friendster • Hi5 • Jive • IBM (Lotus Notes;-)28
  29. 29. Who does not use OpenSocial?• Rebel Alliance • Facebook • Twitter • LinkedIn • XING* • Yammer • Foursquare • Google+ ... * Abandoned it for lack of Security among other reasons29
  30. 30. What’s said about OpenSocial? • 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 OpenSocial gadgets)30
  31. 31. What’s said about OpenSocial (2) • 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)31
  32. 32. SocialSite – Sun’s Approach to Social Sun Microsystems Socialsite: Shindig + gadget based UI written in Java Open Source https://socialsite.dev.java.net/32
  33. 33. The non Standard parts • No standard identity management or any other API across Social Media • More than that. There is no Social Media that guarantee: • Its API won’t change for a given period • Backward compatibility when its API change33
  34. 34. What would be a standard for Social ? • A basic heart providing basic services : • OAuth and Rest request • Multi Social Media connections • Polymorphic services to enforce standard on social Media • Connector definition for Social module • So this standard would be a kind Java Social Connector definition standard34
  35. 35. From JSR 357 to Agorava • Before Agorava there was Seam Social, part of the JBoss Seam 3 project • Early 2012, Seam was stopped to be merged in Apache DeltaSpike • Agorava was born mainly from Seam Social after JSR 357 attempt • One of it’s goals is to be the missing POC for a new Java Social Standard35
  36. 36. Differences to Spring Social • Spring Social works primarily with Spring • Other UI frameworks than Spring MVC are harder to integrate • Focus on Facebook, so far examples only provide Single Service support, unlike Agorava Multiservice approach36
  37. 37. Differences to Spring Social (2) • Despite otherwise still somewhat active Spring community, even at SpringSource / VMware there’s doubt about support and activity, especially after some people left • Currently supports .NET, too37
  38. 38. Differences to DaliCore • Also offering Social Container and CMS, partial OpenSocial support • Persistence support via EJB, JPA, etc. • Not so clear separation of modules, especially API/Spec and Implementation, in most cases they share same module and even package 4938
  39. 39. Differences to DaliCore (2) • Currently seems a little heavier, strong dependencies on the Full Java EE stack, i.e. using only Web Profile or Java SE seems hard right now • Glassfish support and Integration • Demonstrated Scalability also under heavy usage 4939
  40. 40. Differences to Oracle SocialLink • Feels almost like Eclipse or Microsoft project (ISocialNetwork) • Still very new, looks immature in several areas • Seemingly non-existent community support • No Modularity or separation between API and Implementation 5040
  41. 41. Differences to Oracle SocialLink (2) • No Modularity or separation between API and Implementation • Makes less use of Java EE stack and standards than any of the other frameworks even Spring Social • Has fewer dependencies, thus could be ported to Desktop or Mobile/Embedded more easily • No clean Exception hierarchy 5041
  42. 42. Agorava 0.5 Macro architecture • Agorava core is the «smart module» of the framework • Modules are mainly REST API and JSON mapping • Today Agorava provides CDI implementation only • On the roadmap we plan to provide: • Full Java SE support (e.g. CDI 2) • JSR 330 (Guice/Dagger or maybe Spring) support42
