Metalog is a next-generation reasoning system for the Semantic Web. Historically, Metalog has been the first semantic web system to be designed, introducing reasoning within the Semantic Web infrastructure by adding the query/logical layer on top of RDF.

Why?

What is Metalog good for?

• To showcase the potential of the Semantic Web
• To teach the Semantic Web
• To understand how reasoning on the Web can work
• To bring the user in the loop, by making the Semantic Web easier

Design

The design of Metalog comes from the need of blending two necessities of the Semantic Web:

• The first one is reasoning, that is to say, the ability to reason, query, express logical relations. In other words, to do some "thinking" on the Web.
• The second one is to try to make the Semantic Web Easy, or at least to start this quest.

Therefore, Metalog has a double face: a powerful reasoning extension on one hand, and a very user-friendly interface on the other, which constitutes another possible level in the Semantic Web hierarchy: the so-called pseudo natural language (PNL) layer. The PNL (despite its hard name!) makes much easier for everybody to understand the Semantic Web, without having to learn heavy geek-like formalisms: essentially, the way the user interacts is via English-like dialogues, where one can "read" and "write" without having to learn a new different language.

Downloads

The Metalog system is available both for Windows and for Linux platforms. A Macintosh porting is on the way. Check the download page for details and to get the latest Metalog distribution.

Documentation

Every Metalog distribution comes complete with a Quick Guide. There is also the paper Towards a People's Web: Metalog that gives a more technical introdution to the Metalog system, and its future developments.

You can check out the history of the project.

Contacts/Feedback

Comments, suggestions and contributions regarding Metalog are welcomed (Metalog is an open-source project, so everybody is welcome to join and help). Any request or feedback about Metalog can be sent to metalog@w3.org . If you want, you can have a look at the people behind Metalog.

A list of todo's is maintained as well, planning what are the next things on the Metalog agenda.
