XML::Atom::SimpleFeed

XML-Atom-SimpleFeed (CPAN) is a general-purpose Perl module for quickly generating valid Atom feeds, in the style of XML::RSS for RSS. You can see it in action at Iowa Student Computer Association BBS (ISCABBS Est.1989), providing the most recent 30 posts for all public forums, updated every 5 minutes.

Autogenerated Atom/RDF Java

Mark Woodman:

I thought it would be a fun experiment to take an OWL schema for Atom, run it through Kazuki, and generate some easy-to-use classes for Atom in Jena.

(source etc provided)

Henry Story's AtomOWL schema/ontology on the Atom Wiki is the most current (the docs at semtext.org will be updated soon). Henry's also done an RDF Reactor-build set of classes, here.

Raptor 1.4.3

A free software / Open Source C library, the Raptor RDF Parser Toolkit features:

A parser for the multiple XML RSS formats that use the elements such as channel, item, title, description in different ways. Attempts to turn the input into RSS 1.0 RDF triples. True RSS 1.0, as a full RDF vocabulary, is best parsed by the RDF/XML parser. It also generates triples for RSS enclosures.

This parser also handles the Atom 0.3 syndication format currently being standardised by the IETF Atom Publishing Format and Protocol working group.

Also includes serializers for RDF/XML, N-Triples and RSS 1.0.

GMail Atom Feeds

Your client needs to support HTTPS and HTTP Basic Authentication. The feed URI is:
https://gmail.google.com/gmail/feed/atom

Atomic Triples

Raptor is a free software / Open Source C library that provides a set of Resource Description Framework (RDF) parsers generating RDF triples from RDF/XML, N-Triples, Turtle, several XML RSS tag soup formats and Atom 0.3.

Raptor was designed to work closely with the Redland RDF library (RDF Parser Toolkit for Redland) but is entirely separate. It is a portable library that works across many POSIX systems (Unix, GNU/Linux, BSDs, OSX, cygwin, win32). Raptor has no memory leaks and is fast.

mod_speedyfeed

Garrett Rooney:

mod_speedyfeed [for Apache 2] allows you to only send new entries in your Atom feeds down to the clients. The client program adds a few HTTP headers (a If-Modified-Since to tell you what the last time they got was and an A-IM that indicates you support the 'feed' IM) and things just magically work.

In case anyone missed it, there's a $5,000
