At line 31 changed one line
For the third markup line (relation markup), three ontology entities are used. The first (''Ms. Moneypenny'') and third (''Person'') are from the local namespace and therefor the namespace prefix is omitted. The second part is from the predefined rdf vocabulary, therefor the rdf-namespace is used as a prefix by a colon.
On the same page, the [Turtle|Doc Turtle] markup is used to define an owl:Class {{System}} (in the local namespace) and an instance of {{System}} with the name {{KnowWE}}. Additionally, the label "KnowWE Wiki" is defined.

!!!Importing existing ontologies into a KnowWE ontology
By attaching an ontology-file to this page (containing the ontology in any standard ontology format) an ontology can be imported into the KnowWE ontology repository as follows:
{{{
%%Ontology
@import: movie-ontology.owl
%
}}}
__Note:__ For this example a file named ''movie-ontology.owl'' needs to be attached to ''this'' page!
