http://spinrdf.org/spinsquare.html
SPIN Primer: Rectangles and Squares. This document introduces SPIN to people familiar with basic concepts of RDF and SPARQL. A simple model about rectangles and squares is used to introduce all major features of SPIN, including class definitions, constraints, rules, functions and templates. This document can serve as the "Hello, World" example of SPIN. The SPARQL Inferencing Notation - is a W3C Member Submission that can be used to create rich semantic models based on SPARQL.

Composing the Semantic Web. A tool developer's blog on ontology development for the Semantic Web and beyond. Wednesday, May 30, 2007. Default Namespaces considered harmful. In RDF, default namespaces are typically used to minimize the length of resource names. For example, if you have a resource http:/ www.aldi.de/products.owl#Haferflocken and define everything up to the # as your default namespace, then you can abbreviate the whole URI with "Haferflocken" only.

Various types of inference engines exist, including OWL DL tableaux reasoners like Pellet, and Rule engines such as Jena. Even SPARQL can be regarded as an inference engine, because its CONSTRUCT keyword.

Composing the Semantic Web. A tool developer's blog on ontology development for the Semantic Web and beyond. Friday, July 28, 2006. In our recent modeling exercises with real-world customers it became (once more) evident that reified relationships are a key requirement in many domains. Reified relationships are everywhere. As a small exercise I have created an ontology pattern to automatically synchronize a reified relationship with a plain (object) property. I have no idea if this is useful to someo...
