An ontology is created in a similar way as a d3web knowledge base using the ''ontology'' markup.
At line 9 changed 2 lines
%%Ontology
@uses: myPackageName
%%knowledgebase
At line 14 changed one line
For the name {{myPackageName}} please use the name of the [package|Doc Package] that you used for the ontology definitions.
A more detailed description of this markup can be found on the page [Doc KnowledgeFormalization].

At line 22 changed 42 lines
Ontology entities newly created within the wiki are created in the ontology repository under the so-called local namespace, that is the URL referring to the wiki installation URL.
On the wiki pages, the local namespace (''lns'') is ommitted.
!!! Example
The following example defines the package name {{myPackageName}} and creates a new ontology using this package.
{{{
%%Ontology
@uses: myPackageName
%
%%Package myPackageName
%%Turtle
:System rdf:type owl:Class .
:KnowWE rdf:type :System ;
rdfs:label "KnowWE Wiki" .
%
}}}
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!

Ontology entities newly created within the wiki are created under the so-called local namespace, that is the URL referring to the wiki installation URL.
The abbreviation of the local namespace always is ''lns'', i.e. the abbreviated identifier of the local concept Person is ''lns:Person''.
When using ontology entities from the local namespace the namespace prefix can entirely be omitted.
