The document provides an overview of how to build applications for social networks. It discusses social network architectures, fundamentals and requirements which include using web APIs, protocols like HTTP and data formats like JSON. It also covers authentication methods like OAuth and OpenID, and demonstrates how to integrate applications into social networks like Facebook using their APIs.

2. Agenda
• Overview
• How to create application for Social Network?
• Social Network Architecture
• Fundamentals & requirements for building
application
• Demo
• Q&A

3. What is Social Network?
• A social structure made up of actors:
– Individuals
– Organizations
• The dyadic ties between these actors:
– Relationships
– Connections
– Interactions
Or in plain English:
Social networks are essentially about who know who, and who know what.

4. Advantages of Social Networking?
• Work connections
• Keeping in touch
• Get feedback
• Share multiple points of view
• Talking to other persons
• Stay in touch anywhere

5. How do you typically train your team
to use an authoring tools?

6. What is Social computing?
• Social behavior:
– blogs, email, instant messaging, social network
services, wikis, social bookmarking
• Computation:
– collaborative filtering, online auctions, prediction
markets, reputation systems, computational social
choice, tagging, and verification games

7. How can we share?
• A social networking service (SNS) is an online
service that focuses on building and reflecting
of social relations among people, e.g., who
share interests and/or activities
• Basic services
– Profile
– Friend list
– Wall, status, photo, blog….

13. How to create application for
Social Network?

14. What can applications do?
• Encourage communication & collaboration
between members
• Allow members to be more expressive in how
they present their professional identities
• Provide novel functionality that leverages a
member's social network in a moment of need

15. Vocabulary
• They are not widgets?
• Or gidgets…
• They are gadgets!

16. Gadget
• Gadget is really just a mask for something
greater....
• Gadget is just one face of an application

17. Meet the actors
• Viewer
– Always the member currently viewing the gadget.
• Owner
– The member who owns the profile being looked
at. Sometimes also the owner of a canvas page.

18. Meet the container
• A container is a social network that provides
an environment for Javascript and REST
calls, "view" for gadgets to surface on, and
underlying Social Data.

19. Meet the view
• Home Page:
– Primary point of entry for members
– Owner & Viewer are always the same
– Content should be focused on the Member's interaction with the
application
• Profile Page
– Owner is the person who owns the profile
– Information displayed is seen by all who visit the profile
– Content should be focused on what the member does with the
application
• Canvas
– Serves many purposes & contexts for an application
– Owner & Viewer might not be the same. Owner is determined by how
it was navigated to
– Content can be anything related to the application

20. SocialSite Architecture

21. OpenSocial Architecture
Home Server/ Back-end Container Client/Front-end
Apps Social Network Gadgets

22. Container
• Display (Core Gadget Container):
– Widgets in a portal: news, weather
forecast, music, video...
• Social Graph connection (Social Gadget
Container):
– Gadgets with social data: friends
list, groups, activities...

23. Anatomy of an Open Application

24. Fundamental of SNS
• Web API
• Protocol: HTTP, SOAP, REST
• Data Format: JSON, ATOM, XML
• Security: OpenID, OAuth

25. Web API
Google (96): Google Buzz API, Google Plus API
Facebook (8): Facebook API, Graph API, Social Plugin, Realtime
Twitter (3): Twitter API, Twitter Streamming API
….

26. Web Services
• are the key point of Integration for different applications belonging
to different
– Platforms
– Languages
– Systems
• Protocols
– SOAP (Simple Object Access Protocol). SOAP revolutionized RPC and
loose coupling beyond the restrictions posed by earlier protocols
– HTTP based APIs refer to APIs that are exposed as one or more HTTP
URIs and typical responses are in XML / JSON. Response schemas are
custom per object
– REST on the other hand adds an element of using standrdized URIs,
and also giving importance to the HTTP verb used (ie GET / POST / PUT
etc)

28. SOAP vs REST
• The main advantages of REST web services
are:
– Lightweight – not a lot of extra xml markup
– Human Readable Results
– Easy to build – no toolkits required
• SOAP also has some advantages:
– Easy to consume – sometimes
– Rigid – type checking, adheres to a contract
– Development tools

29. RESTful web service (RESTful web API)
A simple web service implemented using HTTP and
the principles of REST. It is a collection of resources,
with four defined aspects:
• URI http://example.com/resources/
• Media type of the data supported is often JSON,
XML , YAML or a valid Internet media type.
• HTTP methods (e.g., GET, PUT, POST, or DELETE).
• The API must be hypertext driven

30. REST
HTTP SQL CRUD
POST INSERT Create
GET SELECT Read
PUT UPDATE Update
DELETE DELETE Delete

31. REST API or Graph API
• Rest API
• Graph API

32. Graph API
• https://graph.facebook.com/ID
• https://graph.facebook.com/ID/CONNECTION
_TYPE
• https://graph.facebook.com/220439?access_t
oken=...

33. Social Graph API

34. OpenID vs OAuth
• OpenID is about • OAuth is about
authentication to many authorization –
sites with one application or site A has
username. permission to call site
B's ap
• Using login credentials • Allowing an application
from an OpenID (TwitPic) to act on your
provider (Google) to behalf to and access
login to another information from an
application (Stack application that you use
Overflow) (Twitter)

35. Authentication
/authorize?client_id
&redirect_uri
login
1
OK
User
permission
App Allow
access_token
2 /redirect_uri?code=
API
/access_token?code&client_id
&client_secret

37. JSON: The Fat-Free Alternative to XML
• JSON object
{
"name": "Jack ("Bee") Nimble",
"format": {
"type": "rect",
"width": 1920,
"height": 1080,
"interlace": false,
"frame rate": 24
}
}
• JSON arrays
["Sunday", "Monday", "Tuesday", "Wednesday", "Thursday", "Friday", "Saturday"]
[ [0, -1, 0],
[1, 0, 0],
[0, 0, 1] ]

38. RSS 2.0 vs Atom 1.0
<?xml version="1.0" encoding="utf-8"?> <?xml version="1.0" encoding="utf-8"?>
<rss version="2.0"> <feed xmlns="http://www.w3.org/2005/Atom">
