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 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

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!

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
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

OpenSocial is not just for friends
There is an untapped Enterprise potential
Instead of friends just sharing photos, messages business partners can interact via social networks
Google is now partnering with many influential business application providers

OpenSocial Roadmap
Version 0.5 was released in a “developer release” on Nov 1st.
First “sandbox” was made available on Orkut
Version 0.6 was released in December
Initial version of Shindig server software was launched as Apache incubator project
Other sandboxes came live - Hi5, Ning, Plaxo …
Version 0.7 (production) was released in January
MySpace, Hi5, Orkut officially launching “very soon”

Open Social Hype Cycle

Current status on (a few) containers hi5 - launched developer platform recently (80 million users): http://www.hi5networks.com/developer/ MySpace - Developer Platform live and beta Apps Gallery available: http://developer.myspace.com orkut – Sandbox available, launch in test phase, apps available to a subset of users (Estonia) - rolling out further in the coming weeks ning, plaxa – sandboxes available

Agenda
JavaScript APIs
REST APIs

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
Server is optional
Share data with your friends, the world
The core OpenSocial services include:

OpenSocial APIs overview
Built on industry standards
XML
Javascript / HTML
REST – XML/HTTP, Gdata, JSON, - tbd.

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 :

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:

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

Demonstration

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

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

Agenda
JavaScript APIs
REST APIs

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)‏

Agenda
JavaScript APIs
REST APIs

opensocial.org
Start getting involved early!
A non-profit entity jointly proposed by Yahoo!, MySpace, and Google
Now available to developers and website owners
Latest specifications
Opportunity to participate in specs discussions (REST API)‏
