Owl-time support in the Jena module


The owl-time standard is a SPARQL schema which supports representing and querying time data on the Semantic Web. This article explains how Geosparql is supported in the Jena module.

Enabling support for owl-time

To enable the support for Geosparql for a Schema, you should set the owlTime property to true in the module properties configuration.

For example:
      <properties>
         <application name="jena">
            <module name="jena">
               <moduleArrayGroupProperty key="schemas">
                  <moduleArrayValue>
                     <moduleProperty value="geo" key="name"/>
                     <moduleProperty value="spatialdata.owl" key="owlData"/>
                     <moduleProperty value="my:" key="prefixNS"/>
                     <moduleProperty value="http://example.org/ApplicationSchema#" key="owlNS"/>
      <moduleProperty key="owlTime" value="true" />
                  </moduleArrayValue>
               </moduleArrayGroupProperty>
            </module>
         </application>
      </properties>

If you don't set the owlTime property, you will have a warning emitted by the jena module about the fact that the hour data property is not defined.
