TagTeam is an RSS / Atom / RDF aggregator with the ability to filter and remix its input feeds with a high degree of flexibility.
Items can be added directly to TagTeam “bookmarking collections” via the provided delicious-like bookmarklet, and these items can be remixed and filtered like any other item.
TagTeam can aggregate content from anything that emits RSS, Atom, or RDF. This includes delicious, zotero, WordPress, twitter, mediawiki, connotea, blogger, github, and too many other applications and services to mention. It uses the feed-abstract gem, written as part of this project to create a better way of dealing with structured feeds. feed-abstract understands some generators and does magical things – like turning twitter hashtags into actual tags on aggregated items.
TagTeam can import Delicious and Connotea backups directly into a bookmark collection, and will support more formats soon.
Remixed feeds are available as RSS 2.0, Atom, and jsonp output and can be viewed directly in a hub. Feeds, FeedItems, and Tags can be added and removed from a Remixed feed contextually within the application.
