“According to Technorati data, there are about 75,000 new blogs a day. Bloggers -- people who write weblogs -- update their weblogs regularly; there are about 1.2 million posts daily, or about 50,000 blog updates an hour.”

Why Tag Feeds?Why Tag Feeds?Why Tag Feeds?Why Tag Feeds?
• Of course, there are several web-based feed readers that allow tagging:
•Technorati • Feedlounge•Rojo • Google Reader•Gregarius • News Alloy
• And one can always tag blogs and news items in Shadows or Del.icio.us.
But…
Why Tag Feeds?Why Tag Feeds?Why Tag Feeds?Why Tag Feeds?
But…• The tag data gets locked into a proprietary system.• Data transfer is difficult, or impossible
• The IMDb dilemma: who profits from my long hours of tagging?
Project GoalsProject GoalsProject GoalsProject Goals
• To create an application that can easily tag RSS feeds and share tags through a social network
• Tags are distributed : not locked in toone application
• Allows users to find relevant information
Project Ideas and Project Ideas and PlanningPlanning
Project Ideas and Project Ideas and PlanningPlanning
• Let the user choose his/her feed reader
• A local application (JAVA)
– Not tied to a specific web RSS aggregator
• Data published to a “metablog”
• Data gathered from other metablogs

• Difficulties:
– Too many feed schema; loose semantics•The Informa Library provided a workable solution ( http://pistos.pe.kr/javadocs/repository/78/0.6.0/docs/index.html )
QuickTime™ and aTIFF (LZW) decompressor
are needed to see this picture.
Collecting Feeds fromthe User’s Feed Reader
The Next Level?The Next Level?The Next Level?The Next Level?
• Adding value for the user: more features for searching and organization
– Using tags to organize one’s own feeds
– A “metablog aggregator” to allow searching across the range of existing tags?
– Applications of this distributed model beyond RSS?
