world's shortest N3 tutorial

Here's all you need to know to start using N3 right now

1). Allows RDF to be shown in a readable, natural, format.
2). Reduces file sizes.
3). You Can learn basic syntax by remembering a few rules.
4). Basic syntax is enough for most situations.

What are the Rules I need to know you ask?

1). Resources must end with a period
2). Use prefixes as much as possible
3). End each triple with a semi-colon
4). [] is short for bnode or anonomous
5). use “a” instead of rdf:type

and finally, an example to consider...

@prefix xsd: .
@prefix : .

[] a :SomeRDFClass ;
:xsdVal xsd:String ;
:hasLiteral “Some Value" .

Just was invited to speak at april 8,9

So look for more posts in the near future regarding the status of some of my open source projects as well as ideas for the presentation. If anyone has a topic they would like to hear about, let me know

Speaking at ETE
