What is OpenSocial?

• OpenSocial is a set of common APIs for building social applications across the web

• It is being developed by Google in conjunction with partners from the Web/Social Application development community

6

Why OpenSocial is Important?

• The Web is better when its social

• Isn’t the Web social already?

• 100s of millions of users already have signed up for social networks around the world

• That’s great, but we believe it can get better

7

The problem of social network development

“.. But what if you want to build an application that will run on multiple social websites?”

• Problem: Developers have to learn multiple APIs to publish in multiple environments

• Solution: OpenSocial allows developers to write applications to a common standard API that will run on multiple websites!

• As each social website opens its environment to developers, it exposes an API

8

OpenSocial solves this problem

10

What can OpenSocial do for the Web?

• It’s about more, more, more • More applications can be built by developers• More websites can run these applications• More users can use these applications

For Web developers this equates to distribution, distribution, distribution!

11

OpenSocial is not GoogleSocial

• The evolution of OpenSocial…

“It is about working with open standards and open partners in a collaborative fashion to build the best technology”

Core Services - People & Friends

/*** Request for friend info when the page loads.*/

function getData() { var req = opensocial.newDataRequest(); req.add(req.newFetchPersonRequest(VIEWER), 'viewer'); req.add(req.newFetchPeopleRequest(VIEWER_FRIENDS), 'viewerFriends'); req.send(onLoadFriends);};

Getting info on you and your friends:

Core Services - People

/*** Callback function for returned friend data.*/

function onLoadFriends(response) { var viewer = response.get('viewer').getData(); var html = 'Friends of ' + viewer.getDisplayName() + ‘:<br><ul>’; var viewerFriends = response.get('viewerFriends').getData(); viewerFriends.each(function(person) { html += '<li>' + person.getDisplayName() + '</li>';}); html += '</ul>'; document.getElementById('message').innerHTML = html;};

Getting info on you and your friends:

Core Services - Activities

/*** Posting a simple text 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("This is a sample activity, created at " + new Date().toString());

Posting an Activity:



Activities in Orkut:

Core Services - Persistence

/*** Storing data*/function populateMyAppData() { var req = opensocial.newDataRequest(); var data1 = Math.random() * 5; var data2 = Math.random() * 100;

req.add(req.newUpdatePersonAppDataRequest("VIEWER", "AppField1", data1)); req.add(req.newUpdatePersonAppDataRequest("VIEWER", "AppField2", data2)); req.send(requestMyData);};

Requesting to persist data:

27


/** * Fetching data*/function requestMyData() { var req = opensocial.newDataRequest(); var fields = ["AppField1", "AppField2"]; req.add(req.newFetchPersonRequest( opensocial.DataRequest.PersonId.VIEWER), "viewer"); req.add(req.newFetchPersonAppDataRequest("VIEWER", fields), "viewer_data"); req.send(handleReturnedData);}

Requesting to persist data:

28


/*** Displaying persisted data*/function handleReturnedData(data) { var mydata = data.get("viewer_data"); var viewer = data.get("viewer"); me = viewer.getData(); // me is global var var data = mydata[me.getId()];

htmlout += "AppField1: " + data["AppField1"] + "<br/>"; htmlout += "AppField2: " + data["AppField2"] + "<br/>"; var div = document.getElementById('content_div'); div.innerHTML = htmlout;}

OpenSocial’s REST APIs

• Why are REST APIs needed?• “What if you don’t have a JavaScript environment?”

• Progress is now being made on the specification for OpenSocial REST APIs!

• A new proposal is been published• Posted in “opensocial-and-gadgets-spec” Google Group

• Currently receiving feedback

http://groups.google.com/group/opensocial-and-gadgets-spec/browse_thread/thread/f5a0cf3707709ffa

37

With REST APIs OpenSocial can go Mobile!

• The OpenSocial Mobile environment potential is obviously huge • Since OpenSocial based on common Web standards programming is straightforward

• HTML/JavaScript• Flash/Flash Lite • REST APIs (Upcoming)
