AgendaAgenda• The Opportunity
– Why is the Internet increasingly obsessed with Facebook?
• The Facebook Platform– Introduction to Facebook and the Facebook Platform
• The Framework– Core components– Tools
• The Anatomy of a Facebook App– How are Facebook Applications built?– Application Architecture– Integration points
• Demo– Creating a Platform Application step by step
Facebook Chases Google and Yahoo. Twitter Left Facebook Chases Google and Yahoo. Twitter Left BehindBehind
Facebook : General Growth Facebook : General Growth • More than 350 million active users • 50% of the active users log on to Facebook in any
given day • More than 3.5 billion pieces of content (web links,
news stories, blog posts, notes, photo albums, etc.) shared each week
• More than 1.6 million active Pages on Facebook • More than 700,000 local businesses have active
Pages on Facebook • Pages have created more than 5.3 billion fans
Facebook : User Engagement Facebook : User Engagement "We're not trying to help you make new friends online. We're just trying to help you digitally map out the relationships you already have." - Zuckerberg
– Average user has 130 friends on the site – Average user sends 8 friend requests per month – Average user spends more than 55 minutes per day on
Facebook – Average user clicks the Like button on 9 pieces of
content each month – Average user writes 25 comments on Facebook content
each month – Average user becomes a fan of 2 Pages each month – Average user is invited to 3 events per month – Average user is a member of 12 groups
Discovering Facebook• Canvas• Publisher• Request, Invitation, Notification• News Feed
– Comment, Like, Share• Profile
– Profile Box– Info Tab– Application Tab
• Application Menu• Application Directory• Application Profile Page• Business/Fan Page• www.facebook.com
Discovering Facebook : News Feed• Your own personalized news channel — something like a FNN
(Friends News Network), Contains a live list of announcements or stories about
– profile changes, upcoming events, birthdays, changes in relationship status, and conversations with other users
– activity of your network of friends on Facebook• whom they befriended, what apps they added, what their Status is.
• Facebook compiles this list of news stories based on several factors - all mixed together into a behind-the-scenes, super-secret algorithm.
– who posted the content, and what type of content it is – your preferences of story types, – frequency settings on specific friends, – the privacy levels of your friends, – a user’s opinion on the quality of a story– how many friends are commenting on a certain piece of content,
• Facebook ultimately retains control over what is placed on the News Feed.
Discovering Facebook : Facebook Pages• A Facebook Page is a customizable presence for an
organization, product, or public personality to join the conversation with Facebook users.
• Looks and behaves like user profiles, anybody can visit• By leveraging the real connections between friends on
Facebook, a Page lets Fans become brand advocates. • Posts by the Page appear in News Feed, giving Pages a
stronger voice to reach their Fans.• Pages have the flexibility of multiple customizable tabs
previously exclusive to user profiles.• There are thousands of Facebook Platform applications built
by 3rd party developers available for use on Page.• Example

Social Sites: While Everyone Falls, Facebook RisesSocial Sites: While Everyone Falls, Facebook Rises
Discovering the Pulse of Facebook:Discovering the Pulse of Facebook:The Social GraphThe Social Graph
• The social graph can be defined as the interconnections that exist among family, friends, and acquaintances that every person has.
• Facebook's stated mission is to model the social graph in digital form as accurately and completely as possible.
• The social graph enables social distribution
• The net effect of the social graph is that groups and application can achieve exponential growth
Introducing the Facebook PlatformIntroducing the Facebook Platform
• People are already building social apps, but they have to reconstruct the social graph all by themselves.
• Facebook launched Facebook Applications Platform in May 2007
• The Facebook platform exposes the social graph to everybody with an idea, enabling rapid social distribution of new application.
• The Facebook platform is optimized for building applications in Facebook, and with more value for people to develop on its base.
The OpportunityThe Opportunity• Earn money with Facebook applications.
– A lot of people in the past few years have earned a lot through Facebook applications by just using some simple strategies.
– Develop a viral application and make it popular amongst Facebook users. – Virality is inbuilt into the system, you just need to harness it.– Cheap and exponential growth – Once your application attracts a crowd you will be able to either display ads on it
or simply sell it to big names who are looking for buying applications that are popular.
• Wealth of Data– Relationship Status– Education & Employment Data– Geographic Data– Interests & Affinities– Not their contact information though!

Facebook Platform : Facebook Platform : StatisticsStatistics• More than one million developers and entrepreneurs from
more than 180 countries • Every month, more than 70% of Facebook users engage
with Platform applications • More than 350,000 active applications currently on
Facebook Platform • More than 250 applications have more than one million
monthly active users • More than 80,000 websites have implemented Facebook
Connect since its general availability in December 2008 • More than 60 million Facebook users engage with Facebook
Connect on external websites every month • Two-thirds of comScore’s U.S. Top 100 websites and half of
comScore’s Global Top 100 websites have implemented Facebook Connect
Platform Core ComponentsPlatform Core Components• The server API (REST)
• Methods that let you add social context to your applications.
• FBML, Facebook Markup Language• Allows you to integrate your application into
Facebook.
• FQL, Facebook Query Language• Query for Facebook user data with a SQL-style
interface without using the API
• FBJS, Facebook JavaScript • developers who want to use JavaScript in their
Facebook applications.
RESTful APIRESTful API• With the API, you can add social context to your
application by utilizing profile, friend, Page, group, photo, and event data.
• The Facebook API is a REST (Representational State Transfer)-based interface.– Method calls are made over the internet by sending
HTTP GET or POST requests to the Facebook API REST server.
– Nearly any computer language can be used to communicate over HTTP with the REST server.
– When you call a Facebook API method, your results normally come back in either XML (the default) or JSON format.
• http://developers.facebook.com/tools.php
Facebook API client librariesFacebook API client libraries • You can develop your Facebook application in whichever
development environment you prefer. Facebook and other third party application developers have created client libraries for these environments.
• Facebook provides official support for – PHP5, JavaScript, Facebook Connect for iPhone, – ActionScript 3.0 (officially supported with Adobe), – Microsoft SDK for Facebook Platform (officially supported
with Microsoft)• The Facebook Platform developer community maintains the
following client libraries : – Android, ColdFusion, C++, C#, Google Web Toolkit, Java,
Perl, Python, Ruby, Ruby on Rails, Smalltalk, VB.NET, Windows Mobile/Facebook Development with the .NET Compact Framework

FBML, Facebook Markup FBML, Facebook Markup LanguageLanguage
• FBML is an evolved subset of HTML with some elements removed, and others which have been added that are specific to Facebook. – ability to easily place social tags within HTML. – awareness of who is viewing the page.– If the logged in user is blocked from viewing the particular info,
nothing renders at all. • Facebook server processes FBML and displays the output in
HTML for rendering in a browser.• On the whole, most HTML tags in the Facebook
environment will render the same as normal HTML– Facebook parses a few HTML tags differently than your normal
HTML.– The form tag renders a form in HTML, adding five additional
hidden input fields—the fb_sig_profile, fb_sig_user, fb_sig_session_key, fb_sig_time, and fb_sig
FBML : Social Data TagsFBML : Social Data Tags• Social data is the core of FBML and the primary attraction to developers.
– <fb:name uid="1160" capitalize="true" /> – <fb:profile-pic uid="12345" linked="true" /> – <fb:eventlink eid="21150032416" /> – <fb:grouplink gid="2541896821" /> – <fb:user-table cols="3"><fb:user-item uid="12345" />

FQL, Facebook Query FQL, Facebook Query LanguageLanguage
• fql.query : returns results in XML or JSON format• Many of the Facebook API calls are just pre-
packaged FQL queries• Key Advantage
– Condensed XML reduces bandwidth and parsing costs. – More complex requests can reduce the number of requests
necessary. – Provides a single consistent, unified interface for all of your data.
• Facebook manages the database connections for you, you do not need to open and close database connections as part of your application.
FQL : SyntaxFQL : Syntax• If you already know SQL, it should be pretty straightforward.
– SELECT [fields] FROM [table] WHERE [conditions] – You can also optionally add on ORDER BY and LIMIT clauses that work like
they do in MySQL
• Get pids in range (1,42) from $user_id's albums, sorted by created date: SELECT pid FROM photo WHERE aid IN ( SELECT aid FROM album WHERE owner=''$user_id'' ) ORDER BY created DESC LIMIT 1,42
• FQL introduces a way of dealing with columns which are themselves structures or arrays – "current_location" column of the user table is a location structure
consisting city, state, zip and country.– You can reference the structures as a whole (SELECT current_location ) or
you can filter them down to only a single field within the structure using dots (SELECT current_location.zip)
• Developer tool http://developers.facebook.com/tools.php
FQL : TablesFQL : Tables album application comment event event_member family friend friend_request group group_member link link_stat mailbox_folder message metrics
note notification page page_admin page_fan permissions photo photo_tag profile standard_friend_info standard_user_info status stream stream_filter user
FQL != SQLFQL != SQL• SELECT * is not allowed. You need to specify all the
fields by name in which you want to include in the result set.
• The FROM clause can only include a single table.• At least one field in the WHERE clause must be
classified as indexable.• JOIN is not supported (though IN subqueries are).• The GROUPBY and COUNT keywords are not
supported.• The BETWEEN and LIKE operators are not
supported.• Because you have read-only access, you obviously
cannot use keywords like UPDATE, DELETE, INSERT INTO, or CREATE TABLE.
FBJS, Facebook JavaScriptFBJS, Facebook JavaScript• Facebook expose certain scripting functionality through a
collection of JavaScript objects that allow you to modify your content on Facebook.
• FBJS objects are made to mimic the functionality of JavaScript as closely as possible, but it may take some getting used to for people who are already adept with JavaScript.
• The JavaScript syntax you've come to know and love (or hate) is exactly the same. You can create objects, use anonymous functions, create timeouts and almost any other thing you can think of. Modifying the DOM tree is slightly different, however.
• Facebook pre-processes the script by parsing through the code and prepending your application ID to the names of your functions and variables.
• This creates a virtual scope for every application that runs within Facebook.
FBJS : The BasicsFBJS : The Basics
• Placing your FBJS – <script> <!-- //--> </script> – <script src="http://foo.com/bar.js"></script>
• FBJS DOM Objects– A handle to an FBJS DOM object can be retrieved by either
calling document.getElementById, or document.createElement.
– FBJS DOM objects implement most of the same methods regular JavaScript objects implement including: appendChild, insertBefore, removeChild, and cloneNode.
– Properties like parentNode, nextSibling, src, href (and many many others) have been redefined as a couplet of getters and setters.
FBJS: Setting Style and ContentFBJS: Setting Style and Content
• Manipulating Styles – obj.setStyle({color: 'black', background: 'white'}); – You need to transform hyphenated style property names into lower
camel case• obj.setStyle(‘marginRight', ’10px')
– FBJS allows you to programmatically work with class styles that you have already defined in your code. :
• addClassName(className), removeClassName(className) • toggleClassName(className), hasClassName(className)
• Setting Content – innerHTML isn't implemented for security reasons. Three alternatives
exist. – obj.setTextValue(newText) can be used to set a literal text value
inside of your DOM object (no HTML or FBML accepted). – obj.setInnerFBML(fbJsStringVar) can be used to put HTML or FBML
inside of your DOM object. Note that you need to create a Fb:js-string object first and pass it in as passing a string literal will result in an error.
<fb:js-string var="welcomeMsg"> <div>Welcome to Poolster</div> </fb:js-string>
– obj.setInnerXHTML(string) is a beta feature that allows you to place a string of XHTML directly into the document. The XHTML is sanitized in JavaScript before being rendered.
FBJS : Using AJAX and DialogFBJS : Using AJAX and Dialog• FBJS supplies a very powerful AJAX object for developers. • Facebook proxies all AJAX requests and optionally runs useful
post-processing on the data returned, such as JSON, or FBML parsing. var ajax = new Ajax();
ajax.responseType = Ajax.JSON; ajax.ondone = function(data) { } ajax.onerror = function() { } ajax.requireLogin = 1;
var load = { "UserName": ‘Ranjan', "Category":’2’}; ajax.post(‘http://www.poolster.com/handler.aspx’, load);
• Dialogs– showMessage(title, content, button_confirm = 'Okay') – showChoice(title, content, button_confirm = 'Okay', button_cancel =
'Cancel')
var d = new Dialog();
d.oncancel = function() { } d.onconfirm = function() { } d.showChoice("Poolster", "Are you sure you want to quit ?", 'Yes', 'No');
Facebook App TypesFacebook App Types• Desktop App• Web App
– FBML • Facebook User• Fan Page• Both
– IFrame– Facebook Connect App
• Mobile App
Facebook ConnectFacebook Connect• Facebook Connect lets users bring their identity and connections
everywhere. Developers can access a user's:– Identity: name, photos, events, and more.– Social Graph: friends and connections.– Stream: activity, distribution, and integration points within Facebook, like
stream stories and Publishers.
• Create more engaging experiences on your website.– Traffic
• Enable over 300 million Facebook users to share your content with their friends on Facebook. Let users publish a story, invite their friends, or send an event. Their friends then click back to your site.
– Engagement• Users can immediately find their friends and engage. More friends leads to more activity
and more pageviews. Connected users create 15-60% more content than users who have not connected with Facebook Connect.
– Registration• Allow login using Facebook connect
– Personalization • Present relevant and targeted information based on a user's profile information.
– Social Context • Highlight friend content and across site. Filter information by friends or people-in-your
network's usage and recommendations.– Social Experiences
• Create new experiences and lightweight actions that allow users to interact with each other and their friends (for example, like, publishing stories, gifting).

Facebook FBML Application ArchitectureFacebook FBML Application Architecture
IFrame application IFrame application
Choosing between an FBML or IFrame ApplicationChoosing between an FBML or IFrame Application
• FBML – Lets you quickly start building an application from scratch, which is
good for a new Facebook developer. – Is likely to be faster on first page loads – paradigm is closer to that of the traditional Web – Gives you easy access to lots of Facebook elements – Lets your application pages have nice URLs – Has a sensible authorization mechanism
• IFrames – Are easier and faster if you have an existing application, widget, or
website if the application utilizes XFBML– Are likely to lead to a faster experience for users over the long run – Let you use the JavaScript, HTML, and CSS that you are used to – Are faster if you are doing a lot of AJAX in your application, since the
requests don't need to go through Facebook proxy – Debugging regular HTML and JavaScript is easier than for FBML and
FBJS given the tools available today – Allow you to use popular JavaScript libraries like jQuery in your code,
but you'd have to modify the library to use it in FBJS, and some things just might not work
Facebook App : Integration PointsFacebook App : Integration Points• Application Directory• Application Profile• Canvas Page• Profile
– Applications Menu– Bookmarks– Application Tabs– Publisher– Feed Forms
• News Feed• Requests• User Dashboard• Interacting with Users
– Notification, Email
Facebook AppsFacebook AppsFinding the right concept Finding the right concept
• Build something interesting– since nestled in a social networking context, apps must be
social.– If its social it will be viral
• Leverage The System– each user brings with them a network of friends that can be
involved• Engage the user
– Provide the opportunity to interact and share elements with each other
– completely free attention to a Facebook application is very rare.
• “One Action Applications” is a proved concept!
Facebook App : ViralityFacebook App : Virality
• Metrics for virality– For every new user how many new user they convert– > 1.4 is exponential growth
• Viral Channels– Request & Invitations– News Feed– Stream– Publisher– Sharing– Notifications– Email– Friend Linking– Messages– Chats – Comments
Facebook App : Other ConsiderationsFacebook App : Other Considerations
• Scalability– Don’t scale until you need to “… unless you’re on Facebook.”– Object Caching
