!!! Definition


The triples of an ontology can be organized in different namespaces. 
For a namespace a corresponding abbreviation is usually defined.

{{{
%%namespace
<<ABBR>> <<URL>>
%
}}}

Also ontologies can be linked to this namespace, that are included as an attachment to the wiki.

!!! Example

The following expression defines an abbreviation {{demo}} for the namespace {{http://www.d3web.de/demo#}}.

{{{
%%namespace 
demo http://www.d3web.de/demo#
%
}}}

By the use of that namespace the following class definition will obtain the URI ''http://www.d3web.de/demo#Car''.



!! Ontology Imports

By attaching an ontology-file to this page (containing the ontology in rdf-xml format) an ontology can be imported into the KnowWE rdf-repository as follows:
{{{
%%namespace 
movie http://www.movieontology.org/2009/10/01/movieontology.owl#
@file: movie:movie-ontology.owl
%
}}}

__Note:__ For this example a file named ''movie-ontology.owl'' needs to be attached to ''this'' page!
