Protege: How to specify restrictions on data properties?

Question

I'm creating an ontology using Protege and would like to specifiy restrictions on data properties. Let's say there is a data property named hasCode . I've defined string as range and would like to further define that the maximum length is 3 characters.

Answer 1

Protege in OWL2 allows you to use the Manchester syntax to define data range expressions. Open the range window, and enter a data range expression.

In this case to limit the length, you can have string[length x].
