Semantic MediaWiki - semantic-mediawiki.org

Semantic MediaWiki (SMW) is a free, open-source extension to MediaWiki – the wiki software that powers Wikipedia – that lets you store and query data within the wiki's pages. Semantic MediaWiki is also a full-fledged framework, in conjunction with many spinoff extensions, that can turn a wiki into a powerful and flexible “collaborative database”. All data created within SMW can easily be published via the Semantic Web , allowing other systems to use this data seamlessly. Found errors or omissions?

LOD2 Plenary Meeting: WebID and Authorization SIG Today morning, we started the main LOD2 plenary meeting in Vienna. The first half day session the WebID special interest group discussed about WebID based single sign for the LDO2 stack and authorization. The challenge here is to provide a interoperable authorization layer which describe user, groups / roles and access to different parts of the stack as well as the managed knowledge bases. We agreed on the following short and long-time goals and activities: WebID registration service and stack internal authorization policy.
You’ve looked at various XML schemas and microformats , but none of them really describes all the information that you want to publish. Should you invent a new format? It’s tempting, but if you could use an existing standard, your data would be immediately interoperable with other data published in the same way; people could reuse the tools, parsers and stylesheets built around that standard. http://www.digital-web.com/articles/rdf_for_the_rest_of_us/

Digital Web Magazine - RDF For The Rest Of Us

And they weren't interested. And in less than a year, they were gone. And I thought about where we're right today and where we might be wrong, and why. Because despite having a pretty good track record (check for yourself, it's all on the public record - this year's predictions (bucking everyone else) include OpenID and the runaway success of Wii). And I was thinking about the edgy things of Web 2.0, and where they're working, and more importantly, where they're beginning to show some cracks. http://halfanhour.blogspot.com/2007/03/why-semantic-web-will-fail.html

Why the Semantic Web Will Fail

The Semantic Web is a collaborative movement led by the World Wide Web Consortium (W3C) [ 1 ] that promotes common formats for data on the World Wide Web . By encouraging the inclusion of semantic content in web pages, the Semantic Web aims at converting the current web of unstructured documents into a "web of data". It builds on the W3C's Resource Description Framework (RDF). [ 2 ] According to the W3C, "The Semantic Web provides a common framework that allows data to be shared and reused across application, enterprise, and community boundaries." [ 2 ] The term was coined by Tim Berners-Lee , [ 3 ] the inventor of the World Wide Web and director of the World Wide Web Consortium (" W3C "), which oversees the development of proposed Semantic Web standards. He defines the Semantic Web as "a web of data that can be processed directly and indirectly by machines." http://en.wikipedia.org/wiki/Semantic_Web
