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

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

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

OpenSocial solves this problem

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!

OpenSocial is not Google Social
The evolution of OpenSocial…
“ It is about working with open standards and open partners in a collaborative fashion to build the best technology”

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 API
Share data with your friends, the world
The core OpenSocial services include:

OpenSocial APIs overview
Gadgets Core Utilities handling gadget preferences, IO, JSON
Gadgets Feature-Specific Utilities for working with flash, window management, tabs, rpc, MiniMessage
Additional Gadgets services include:

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 : Generated output:

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:

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:

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: Generated output:

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”

Shindig Components Shindig Gadget Server Gadget Container JavaScript OpenSocial Container JavaScript Gadget Rendering Servlet
Gadget Server
Renders gadget XML (i.e. from gmodules.com)
Gadget Container JavaScript
OpenSocial Container JavaScript
JavaScript environment for people, activities, persistence
OpenSocial Gateway Server
WIP!

Shindig in Action Running the application Request is made from Client Data is returned and rendered Application Installation Gadget XML is loaded and cached on OpenSocial Container Gadget XML Source

Demonstration
Checking out the Shindig website
Running and Debugging Shindig from Eclipse
Trying out the SampleContainer

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

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)

With REST APIs OpenSocial can go Mobile!
