Hi all, I just remembered there already is a similar DBpedia property: runtime [1][2]. It even declares schema:duration as owl:equivalentProperty.
The name 'runtime' is less than perfect and only applies to movies etc, 'duration' is more general. For example, schema.org/Movie also uses schema:duration. Maybe we should have renamed 'runtime' to 'duration' instead? While it's on our wiki, I just changed schema:duration from ObjectProperty to DatatypeProperty. It has range schema.org/Duration, which because of the capital D looks like a class, but is actually a datatype that looks equivalent to xsd:duration. At first I liked the idea of using schema.org properties and types, but maybe we should wait until the RDF schema for schema.org is published and used. For example, schema:duration doesn't have a dereferencable URI yet.
