Yet Another RSS FAQ
Julian Bond writes "I've embarked on building yet another RSS FAQ, loosely based on all the
other RSS FAQs. This one has a subtle difference though. Through the magic of Drupal it's got a /. style comment and submission system so anyone with the
time can help build and maintain it." Read more and contribute at http://www.voidstar.com/rssfaq.
MulleNewz 1.0 Released
"MulleNewz is a dockling which allows you to stay in touch with the world via the OSX dock! It is an easy to configure RSS reader which means that it can access a lot of popular sites that offer RSS content - at once! Just click on the headline you're interested in and MulleNewz will open your preferred browser and direct it to the URL containing the whole story." Available from here.
Morbus Iff Joins RSS Info
Morbus Iff, the creator of AmphetaDesk, has joined the news grubbing, list reading, standard following crew of RSS Info. He hopes to contribute enough loving to make RSS Info the shining beacon of syndication news and development. He also hopes to stop using these horrifically convoluted sentences.
Jeff Barr Updates Syndicated Alias List
Jeff Barr's alias list, used internally in his Headline Viewer, has recently been updated. "The file exists to make it possible to recognize aliased
syndication URLs that ultimately refer to the same root data
source." Read his full announcement here.
Reptile 0.0.1 Released
"Reptile is an Open Source/Free Software, Peer-to-Peer, content syndication engine (think RSS/OCS), which is driven by Java/XML and is privacy protection/Reputation enabled. Reptile nodes can publish to each other (everything is driven by XML based subscriptions) and provides a decentralized authentication model based on public/private key crypto (and Reputation)." See more here.
Meerkat Adds Support for Dublin Core
Meerkat, the O'Reilly Network's syndicator, now displays Dublin Core metadata in feeds. (Example, RSS, N3). The new version of the website also allows you to do searches based on Dublin Core metadata. Getting everyone to support new modules is often an chicken-and-egg problem, but we're glad Meerkat has taken the first step.
Peerkat Released
Rael Dornfest has released Peerkat, a personal aggregator/syndicator for your desktop. Peerkat is an open source project and everyone is encouraged to get involved on the mailing list and at the SourceForge project page.
WebReference Provides Comprehensive Article on RSS
Andy King has written a very comprehensive article on RSS in all its various forms and manifestations. It's available on WebReference.com.
Dave Winer Announces RSS 0.93
Today, Dave Winer announed his plans for RSS 0.93 and the process by which it would be created. He is asking for suggestions (email list) and plans to take the best ones and add them to the spec. However, he does ask that things are kept simple and non-RDF.
New Compatibility Comparison
We now provide a compatibility comparison of the various RSS specs.
RSS Info Provides New Feeds
RSS Info is pleased to provide a series of RSS feeds scraped from popular websites on the Net.
Dave announces RSS 0.92
Dave Winer has announced RSS 0.92 a forwards-compatible modification to RSS 0.91 to support new software from UserLand called "My.UserLand On the Desktop".
RSS 0.92 makes the language element optional and introduces some new elements:
cloud describes a system for subscribing to updates of the RSS file
enclosure describes a large external file to be sent with the RSS file
As Dave has said he is "not doing this as part of a working group, or in collaboration with anyone else."
RSS 1.0 Released!
At long last and with much rejoicing, RSS 1.0 is finally released. The vote passed unanimously with 9 members of the WG (and one non-member) voting. Strangely enough, the message that announced the results of the vote was exactly message 1300. It was followed by a message from Rael Dornfest, the WG Chair, recapping the 4-month process that it took the spec to finally be published.
News of the release has been covered on XMLhack. Rael also posted a note to his blog. In addition, O'Reilly has issued a press release.
Squish: An RDF Query Language
Libby Miller has released Squish an RDF query language. The syntax is a lot like SQL, and Squish sits on top of an SQL backend like Postgres. Its demos show it working with RSS. Take a look.
RSS Tool Overview
Thanks to Ken McLeod, we have an RSS tool overview. We encourage everyone to submit additions and comments to that page and our RSS tool listings.
RDF::RSS Demo
Dave Beckett has announced a demonstration (source) of his RDF::RSS module. I believe this is the first public demonstration of a RSS file being processed by an RDF parser. Neat!
