• rome - a set of Atom/RSS Java utilities to support most syndication formats. (P@: 5 active developers, tons of documentation, active traffic in users and dev mailing list, enters beta soon, handles all formats, many subprojects)
• [general] j-rss-bayes -- (http://j-rss-bayes.dev.java.net/) bayesian filter (P@: this is not a project, it is just a 3 lines proposal from 18 months ago, with 2 email messages asking if this project is useful, nothing else. You should delete it from the community if his author agrees)
• [general] jrss - (http://jrss.dev.java.net/) rss library (like rome) (P@: updated last march 2004, 1 developer, no traffic in mailing lists, no docs, seem to have a small ui and handle only rss 2.0 and its ancestors: don't compare that to Rome please;-)
• [javadesktop] fetchrss -- (http://fetchrss.dev.java.net/) but never used it. (P@: it's Crazybob's RSS to email gateway, 1 developer (but very good), haven't seen any docs. Updated last time august 2004, stable, no more active development. Not sure which versions he handles.)

An example of an aggregator

• Meerkat Open News Wire service : http://www.oreillynet.com/meerkat/
• Meerkat is a very comprehensive aggregator with a lot of features like filtering by topics, time or keywords, and it can provide an automatic behavior.

• Incorporate Patrick's content from https://jwsdp.dev.java.net/collaboration/index.html

The same way that most people do not read raw HTML, most people do not read raw RSS feeds. Instead, they, directly or indirectly, rely on some software to read the new feeds. The most popular approaches are:

• Visit an web page that will do the work for you. The categories are a bit fuzzy but for the most part they can be described as either plain web readers, aggregators or search engines,
• Use a specialized desktop reader tool to query the feeds, or
• Use a browser or mail reader that recognizes RSS directly, like FirefoxAndThunderbird

Projects at Java.Net

Desktop Readers

• Multi-platform -- FirefoxAndThunderbird, the latest browser and mail reader from Mozilla.org.

Older browsers can also support RSS reading either through a plug-in or just by using Javascript plus frames. For example:

• Browser-based -- RocketInfo, NewsMonster.

Web Readers

Here are some in the area of the Java platform

Other links to incorporate somewhere

Arguably some of this should go in the Javapedia.

Other Software Projects

• UFP (python-based - Universal Feed Parser)

• Javacrawl.com --
• JavaRSS.com --
• PlanetJava.org --

Search Engines

• Technorati -- A real-time search engine that keeps track of what is going on in the blogosphere — the world of weblogs.
• Feedster -- Search engine and aggregator.
• PubSub -- A public matching engine; match new data to user subscriptions, all the time, in (near) real time.

Other Links TBD

RSS Corner

This area is intended to collect information on RSS which is used by Blogs (Web Logs) and many other projects.

Basics

RSS stands for Really Simple Syndication (it originally stood for RDF Site Summary -- see an RSS history) and it is a format for delivering syndicated content. It really is not a single format but a collection of formats; the whole list includes RSS 0.90, 0.91 Netscape, 0.91 Userland, 0.92, 0.93, 0.94, 1.0 and 2.0, as well as the new Atom standard. There is a fair amount of history behind the different formats exist; the main consequence is that sometimes a reader will not be able to process some content, although the readers are moving towards accepting all content.

RSS is often used to read blogging (web logging) and news. In both cases a source (a feed) is identified by a URL. The feed contains a machine-readable description of the content available, a short description, and a URL for more complete information. A reader may keep a list of feeds and also a list of items that have been read so it can only show new content.

Some good pages for introductory material on RSS are available at Google and others.

Publication Dynamics

Authors, Readers, Bloggers, News Feeds, Search Engines, Cross-Links, etc. ?

Software

Java Projects

There are a number of RSS-related projects at Java.Net. Some of them would be a good fit in WS and XML community (I think) -

• rome - a set of Atom/RSS Java utilities to support most syndication formats.
• [general] j-rss-bayes -- (http://j-rss-bayes.dev.java.net/) bayesian filter
• [general] jrss - (http://jrss.dev.java.net/) rss library (like rome)
• [javadesktop] fetchrss -- (http://fetchrss.dev.java.net/) but never used it.
• [javadesktop] planet-on-wire -- desktop RSS client
• [javadesktop] rssclient -- but won't consume RSS 1.0?

Readers

Rss is starting to be quite pervasive and there are a number of reader tools. Some popular ones are listed below, grouped by platform:

• Mac OS X -- NetNewsWire, and its free lite companion.
• Windows -- SharpReader.
• Linux -- Straw.
• Multi-platform -- RssFirefoxAndThunderbird^?, the latest browser and mail reader from Mozilla.org.
• Browser-based -- RocketInfo, [[http://www.newsmonster.org/][NewsMonster].
• Server-side -- Bloglines.

Aggregators

There are so many RSS feeds that a number of sites have appeared that just aggregate feeds. Here are some in the area of the Java platform

• Javacrawl.com -- XXX
• JavaRSS.com -- XXX
• PlanetJava.org -- XXX

Popular Feeds

TODO

• Javapedia - How much of this should just go in Javapedia?
• Technorati - describe.
• UFP (python-based - Universal Feed Parser)
• Feedster
• PubSub^?
• Publishing Software (like Movable Type)
