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 it's 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

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

“.. 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!

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

• Making the web more social, not just Google

• The evolution of OpenSocial…

“Working with open standards and open partners in a collaborative fashion to build the best technology”

• Engineers and developers talking to engineers and developers

21

OpenSocial APIs overview

• People and Friends Data API Access friends information programmatically • Activities Data API See what you’re friends are up to Share what you are doing

• Persistence Data APIServer is optionalShare data with your friends, the world

The core OpenSocial services include:

22

OpenSocial APIs overview

Built on industry standards

• XML • Javascript / HTML

• REST – XML/HTTP, Gdata, JSON, - tbd.

23

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:

24

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:

25

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:

26

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

Core Services - Persistence

/** * 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

Core Services - Persistence

/*** 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;}

Displaying the fetched (persisted) data:

29

0.7 Highlights

Production ready!

• Viral growth requestShareApp(), requestSendMessage()

• Feature support querying supportsField()

• Standardized person fields location, affiliations, status, profile pictures, DOB, etc.

• Gadget specs re-namespaced ie. gadgets.IE_Adjust_Frame_Height

• Better environment support methods to determine locale

• Built in JSON support

30

Demonstration

• Building some simple OpenSocial apps in Orkut• Displaying your friends• Give gifts to your friends• Show what you've given• Show what you've received

• Reviewing other OpenSocial applications

OpenSocial’s Container - Shindig

• What is Shindig?• “OpenSource software that allows you to serve OpenSocial

applications”

• Is currently an Apache Software Incubator project• Heavy partner involvement: Ning championed• Open source reference implementation of OpenSocial & Gadgets technologies

• It’s Goal: “To serve as an easy to use OpenSocial “container in a box”

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

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)
