Introduction to Semantic Web Vision and Technologies

This multi-part series at SemanticFocus provides a great way to learn about the Semantic Web vision and its associated technologies. The series starts with basic concepts and then gradually builds to more advanced concepts. Follow this course to accelerate your journey to Semantic Web mastery!

Part 1 - Overview
This is the first of a series of articles written exclusively to help the Semantic Focus community understand the Semantic Web vision and technologies. In this part, we introduce the Semantic Web vision set forth by Tim Berners-Lee. We also took a look at the famous layer cake diagram illustrating key technologies that make it possible.

Part 2 - Foundations
In this part, we munch around the bottom of the layer cake with a few important points about Unicode, URI, and XML - - three foundational technologies that permeate the existing Web and that are especially relevant to the emerging Semantic Web.

Part 3 - The Resource Description Framework
We put Unicode, URI, and XML to use as we take our next step up the Semantic Web layer cake in a review of the Resource Description Framework (RDF). At the same time, we take the visual RDF/OWL editor, Altova SemanticWorks, for a test drive.

Part 4 - Protégé 101 (screencast tutorial)
We reach an important milestone in the series - crossing a great divide between familiar technologies such as XML, Unicode, URI, and RDF to the Web Ontology Language (OWL). This is where things really start to get interesting.

Part 5 - Building OWL Ontologies Using Protege 4 (screencast tutorial)
We're still using Protege, but this time working with the new ALPHA version and getting deeper into concepts.
