Oracle 10g Release 2 / Oracle 11g offers a robust, scalable, secure platform to store RDF and OWL data. It allows efficient storage, loading and querying of semantic data. Queries are enhanced by adding relationships (ontologies) to data and evaluated on the basis of semantics. Data storage is in the form of RDF triples (Subject, Predicate, Object) and can scale up to millions of triples. The triples stored in the semantic data store are modeled as a graphed structure. All the data is stored in a single central schema allowing access to users for loading and querying data.

Update: 302 Semantic Web Videos and Podcasts!

I've compiled a list of videos about the Semantic Web, RDF, and OWL for your viewing pleasure! Most of these videos are short, ranging from about 6 to 10 minutes while others are long (45+ minutes). Included are a few introductions, a few interviews, and a few that get into the gritty details.

We're still using Protege, but this time working with the new ALPHA version and getting deeper into concepts.

Today we reach an important milestone in this series. We are crossing a great divide between familiar technologies such as XML, Unicode, URI, and RDF to the Web Ontology Language (OWL). This, my friends, is where things really start to get interesting because this is the point where the Semantic Web vision really starts to take form. Today, we present a screencast exhibiting Protégé — a free, open source ontology editor and knowledge-base framework developed by Stanford Center for Biomedical Informatics Research at the Stanford University School of Medicine. In this screencast, we show you how to develop a useful Semantic Web-ready application in just minutes. You will learn how to model a very simple ontology in OWL (the Web Ontology Language).

Hey everyone, I've gathered some good reading material for your enjoyment! If you're new to the Semantic Web or just want to brush up on your knowledge then take a look at the following articles. Listed below are over thirty introductions, primers, references, guides, and tutorials on the Semantic Web, RDF, OWL, SPARQL, and GRDDL. If you know of other articles that would fit well here leave me a comment and I'll be happy to add them to the list. Enjoy!

Microsoft has taken steps in the direction of supporting Semantic Web standards such as RDF, OWL, and SPARQL. While their support is minimal and not hyped very broadly it is still nice to see the them implementing these standards in their software. I also haven't seen any evidence that they wish to formulate a proprietary brand of these standards, so I have no complaints.
