Updates about the OpenSocial ecosystem at Google developer days Madrid including presentations from Netlog and Viadeo.

OpenSocial is an open specification defining a common API that works on many different social websites, including MySpace, Plaxo, Hi5, Ning, orkut, Friendster and LinkedIn, among others. This allows developers to learn one API, then write a social application for any of those sites: Learn once, write anywhere.

In addition, in order to make it easier for developers of social sites to implement the API and make their site an OpenSocial container, the Apache project Shindig provides reference implementations for OpenSocial containers in two languages (Java, PHP). Shindig will define a language specific Service Provider Interface (SPI) that a social site can implement to connect Shindig to People, Persistence and Activities backend services for the social site. Shindig will then expose these services as OpenSocial JavaScript and REST APIs.

In this session we will explain what OpenSocial is, show examples of OpenSocial containers and applications, demonstrate how to create an OpenSocial application, and explain how to leverage Apache Shindig in order to implement an OpenSocial container.

  • How To Build OpenSocial Applications
  • People & Friends Example Requesting friend Info function getFriendData() { var req = opensocial.newDataRequest(); req.add( req.newFetchPersonRequest(VIEWER), 'viewer'); req.add( req.newFetchPeopleRequest(VIEWER_FRIENDS), 'viewerFriends'); req.send(onLoadFriends); }
  • People & Friends Example Callback function for returned friend data function onLoadFriends(resp) { var viewer = resp.get('viewer').getData(); var viewerFriends = resp.get('viewerFriends').getData(); var html = 'Friends of ' + viewer.getDisplayName() + ‘:<br><ul>’; viewerFriends.each(function(person) { html += '<li>' + person.getDisplayName()+'</li>';}); html += '</ul>'; document.getElementById('friends').innerHTML += html; }
  • Activities Example Posting an activity function postActivity(text) { var params = {}; params[opensocial.Activity.Field.TITLE] = text; var activity = opensocial.newActivity(params); opensocial.requestCreateActivity( activity, opensocial.CreateActivityPriority.HIGH, callback); } postActivity( quot;This is a sample activity, created at quot; + new Date().toString());
  • Persistence Example Persisting data function populateMyAppData() { var req = opensocial.newDataRequest(); var data1 = Math.random() * 5; var data2 = Math.random() * 100; req.add( req.newUpdatePersonAppDataRequest(quot;VIEWERquot;, quot;AppField1quot;, data1)); req.add( req.newUpdatePersonAppDataRequest(quot;VIEWERquot;, quot;AppField2quot;, data2)); req.send(requestMyData); }
  • Persistence Example Fetching persisted data function requestMyData() { var req = opensocial.newDataRequest(); var fields = [quot;AppField1quot;, quot;AppField2quot;]; req.add(req.newFetchPersonRequest( opensocial.DataRequest.PersonId.VIEWER), quot;viewerquot;); req.add(req.newFetchPersonAppDataRequest(quot;VIEWERquot;, fields), quot;viewer_dataquot;); req.send(handleReturnedData); }
  • Persistence Example Displaying fetched (persisted) data function handleReturnedData(data) { var mydata = data.get(quot;viewer_dataquot;); var viewer = data.get(quot;viewerquot;); me = viewer.getData(); // me is global var var data = mydata[me.getId()]; htmlout += quot;AppField1: quot; + data[quot;AppField1quot;] + quot;<br/>quot;; htmlout += quot;AppField2: quot; + data[quot;AppField2quot;] + quot;<br/>quot;; var div = document.getElementById('content_div'); div.innerHTML = htmlout; }
