Ontology for points in a three-dimensional space

Does anyone know of such a thing? Basically I want something like:

:Point a rdfs:Class ;
    rdfs:comment "A point in three dimentions"@en .
:x a rdfs:Property ;
    rdfs:domain :Point ;
    rdfs:range xsd:decimal .
:y a rdfs:Property ;
    rdfs:domain :Point ;
    rdfs:range xsd:decimal .
:z a rdfs:Property ;
    rdfs:domain :Point ;
    rdfs:range xsd:decimal ;
:plane a rdfs:Property ;
    rdfs:domain :Point ;
    rdfs:comment "The reference plane."@en .

Effectively something like <http://www.w3.org/2003/01/geo/> but  
operating on arbitrary 3D reference planes instead of just WGS84.
