[edit] Web2.0 Features
- Publish - Find - Bind service (Ebay/Amazon/Del.icio.us)
- Web is the platform
- Low barrier to contribution - Use users to add value
- Push/Pull - selective about info you want to see
- Service evolution - perpetual beta
[edit] Data type specific apps - Commodities
- Examples: Flickr, Del.icio.us, YouTube, blogs
- Data has value, the application is a commodity
- Apps have value by themselves - Organize your own content - store your own resources on web
- you control your own content
- Tag based organizing
- Access from anywhere
- Share - Systems get better as more use them - Find/Harvest/Filter Content of particular type
- Community decides what is important
- Navigate multiple axis (tag, user, popularity ...)
- Share resources
- Network Effect by default - move to the web, so everyone tagging for their own purposes creates a pool of value-added links with no extra effort to share
- Because online can be reused multiple times (RSS/URL) with no extra effort(barriers to reuse very low)
- unanticipated ways of reuse
- Profile for type of data i.e. del.icio.us has link, description and tags
[edit] Del.icio.us
Adds human filterng and additional classification/metadata to existing links.
Consequences
- Easier to find relavent pieces of information
- trivial network creation
- exploration - what are good links others have found.
- The primary use of del.icio.us is to store your bookmarks online,
- allows you to access the same bookmarks from any computer and add bookmarks from anywhere
- Share with others in your network:
- see the interesting links that your friends and other people bookmark,
- share links with them in return.
- browse and search del.icio.us to discover the cool and useful bookmarks that everyone else has saved -- which is made easy with tags.
[edit] What have we done with it
We have used del.icio.us to create dynamic lists. We learned to tag links with actions, i.e. ToRead or ToFix. By giving a standard set of tags we created a way of community sharing without needing one common log in. Used RSS to feed lists of resources into the wiki - gave a way to collect from multiple sites and list in one place. Shared links with each other through For:Rhusar.
most popular -
These tools are used mainly for harvesting content from the community through search
[edit] Flickr
Primary use to share photos - enable input into the system from many sources (web, phone, desktop.) Organize photos through tags and self/community provided meta data.
[edit] YouTube
YouTube is an online video streaming service that allows anyone to view and share videos that have been uploaded by our members.

[edit] Virtual Workspace
- Examples: Wikis, google groups, myspace, facebook ...
- Collaboratively write and discuss
- Versioning/archive
- open
- User-defined layout/Structure
- Relational - tag-based, not hierarchical folders
- Organize different kinds of content - wiki can harness and integrate other services but it's up to user to assemble the parts in an innovative way - Situational applications
- Small pieces loosely joined
- Mash through RSS feeds or URL
- upload docs
- creating "records" on wiki pages
[edit] Wikis
Wikis, originally used to collaboratively write and discuss documents, are now also used as a general user-defined workspace to organize web content and as a client for mashups through incorporation of RSS feeds, Google Maps, structured data etc. The Georgia Smoke Event wiki page is an example of this functionality, containing structured metadata which describes the event in a standard way, links to harvesting queries, data resources viewable in Google Earth as well as providing an event summary written and discussed collaboratively by the community.
[edit] What we have done with the wikis
- Used them to create situation-specific websites, easily modified by the community
- Began tagging pages - new tagging of pages as composite/atomic so that we could create a composite page
- Input box allowed user to easily create new page with tags already included - with automated tagging, pages were listed in the correct lists automatically.
- Wanting to have lists of resources outside the wiki - we have used del.icio.us to rss structured tagged resources.
- semantic wiki allows attributes and relations to be established through tagging - making different types of "profiles" for classes of pages (i.e. datasets, tasks, ...)
- Semantic wiki also has a form feature making it more user friendly.
[edit] MySpace/Facebook
Facebook incorporates the structured attributes of a profile with the additional functionality of plugins/comments/content management ...
