“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.

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?
