Web 2.0 Overview
Web 2.0 Examples
Social Networking
Social Networking Software
– Site
– Online Dating
– Mobile
• What’s in Common
• My Project
Supporting Web 2.0
• Refers to light-weight business models providing
services rather than software products
• Server-side web applications provide light-weight
user interfaces
– User interacts through a web browser
– AJAX utilities provide rich user experience
• Development and updates evolve continuously
– “Perpetual beta”
– Users interaction drives software changes
– Users act as co-developers
• Database
– Store, organize, and manage user data
– Data changes quickly
Web 2.0 Mechanism
• Provide data management services
– Service evolves with user experience
– Users determine how they’ll use the service
• Users act as data sources
– Provide content
• Richness of content grows as more people
contribute
– Data gains more meaning/relevance
– Utilizes the “collective intelligence”
• Syndication
– Don’t dictate how data is used
• Reuse
– Incorporation into or combination with other services
Web 2.0 Services
• Google
– Mail, maps, calendar, word processing, spreadsheets, etc
• SourceForge.net
– User-created open source software project

The Blog
• Personal web pages have been around since
the dawn of the web
• The web log altered the paradigm
– The personal web page in journal form
– From static web content to continuously updated
content
• RSS provides the static link to this ever
changing content
– Provided the first mechanism for syndication
– Separates content from any fixed display of it
– Alerts interested users to new content
The Blog
• Linking became the currency of the
“blogosphere”
– Authors include links to other blogs in their own
– Back links let an author count how many people
linked to his blog
– Collective intelligence syndicated the best content
– Formation of communities
• Social Networking
• Notice the implicit association
– Blog still associated with the person
– Each blogger creates a personal profile
Social Networking
• Involves the formation of interpersonal
relationships
– Business, academic, dating, hobbies, sports, and
activities
• In the context of Web 2.0
– Web service provides representation of these real
world relationships
• Friends, business partners, or teammates
– Organize digital information relevant to or indicative of
these relationships
– Context provides the means to find and create new
relationships with different people

The Problem
• Separate databases store almost exactly the
same information
• Attempt to create an online representation of a
person
– Online presence
• Updating the information becomes cumbersome
– Must visit each system separately
• Friends of a user have little or no knowledge of
content provided by other services
My Project
• With an open standard
– Tag common profile information with MWAC tags
– Present an XML document containing all the information
• Much like RSS
• Each service that requires a user’s profile information can syndicate
the document
– Present it however the service needs
– Poll for updates to the document
• Back links provide means of finding other services of which the user
makes use
• Issues
– Identity and Authentication
– Privacy
– Not every service needs access to the same data
• User may want different data displayed for different services
My Project
• Designing a Web 2.0 service could
mitigate these issues
• Provides easy update of Profile
information
• Let’s the user define access privileges to
each service requesting data
• User can also define a profile context
– Services restricted to particular context
Extensions & Other Applications
• Extension for Intellectual Property
• Linking with “Real World” identity information
– Bank accounts
– Government ID
– Using existing services
• Live Resume
• Applications
– Employment
– College/Graduate School/Fellowships
