OWL, UML, SPARQL, templates: TwoUse examples

This video shows how to start using the twouse toolkit by examples:

• SPARQL Querying
• OWL Ontology Template
• OWL Graphical Notation
• OWL Functional Syntax
• SWRL Rule Graphical Notation
• SWRL Rule with UML Profile for SWRL
• SPARQLAS Query
• OWL Ontology with UML Profile for OWL

Creating SWRL Rules with OWL Editor

SWRL Rules could also be created with the OWL Editor. This Editor allows a graphical creation of Ontologies and their SWRL Rules.

Example:

The image shows an Example of a SWRL Rule in the OWL Editor. The Example is the Uncle Rule.

The Uncle Rule in the Syntax Protege is using looks like this:
Person(?x1), Person(?x2), Person(?x3), hasBrother(?x2, ?x3), hasParent(?x1, ?x2) -> Person(?x1), Person(?x3), hasUncle(?x1, ?x3)
