Import a CAD file to Protege

I have modeled an ontology in Protege. Now I need to instantiate the different data I have. For example, I have some CAD files. How can I link them to my ontology? Is there a special Protege plug-in for this?

There is no native way to this in Protege. However, your ontology could define a way in which this can be done. Since you do not give any detail regarding your ontology, I made some assumptions wrt your ontology:

  1. It defines some artifacts for which designs can exist, i.e., a vehicle part, a component, a building etc.
  2. A design is defined using a CADFile.

Here is a minimal ontology to achieve this:

@prefix : <http://www.semanticweb.org/mydesigns#> .
@prefix owl: <http://www.w3.org/2002/07/owl#> .
@prefix rdf: <http://www.w3.org/1999/02/22-rdf-syntax-ns#> .
@prefix xml: <http://www.w3.org/XML/1998/namespace> .
@prefix xsd: <http://www.w3.org/2001/XMLSchema#> .
@prefix rdfs: <http://www.w3.org/2000/01/rdf-schema#> .
@base <http://www.semanticweb.org/mydesigns> .

<http://www.semanticweb.org/mydesigns> rdf:type owl:Ontology .

:Artefact rdf:type owl:Class ;
          owl:disjointWith :Design .


:Design rdf:type owl:Class .

:hasDesign rdf:type owl:ObjectProperty ;
           rdfs:domain :Artefact ;
           rdfs:range :Design .


:isDefinedByCADFile rdf:type owl:DatatypeProperty ;
                    rdfs:domain :Design ;
                    rdfs:range xsd:anyURI .

It states that we have Artefacts and Designs. An Artefact can have Designs and are defined by CAD files.

Example data we may have for this ontology is:

:superFastSportsCar rdf:type owl:NamedIndividual ,
                             :Artefact ;
                    :hasDesign :performanceFocussedFuelInjector ,
                               :superiorTransmissionDesign .
                               
:performanceFocussedFuelInjector rdf:type owl:NamedIndividual ,
                                          :Design ;
                                 :isDefinedByCADFile "file:/filelocationOfPerformanceFocussedFuelInjector"^^xsd:anyURI .

:superiorTransmissionDesign rdf:type owl:NamedIndividual ;
                            :isDefinedByCADFile "file:/filelocationOfSuperiorTransmissionDesignCADFile"^^xsd:anyURI .

:economyVehicle rdf:type owl:NamedIndividual ,
                         :Artefact ;
                :hasDesign :fuelEfficientEngine .



:fuelEfficientEngine rdf:type owl:NamedIndividual ,
                              :Design ;
                     :isDefinedByCADFile "file:/locationOfFuelEfficientEngineCADfile"^^xsd:anyURI .

It defines 2 artefacts, superFastSportsCar and economyVehicle. superFastSportsCar has designs for performanceFocussedFuelInjector and superiorTransmissionDesign. For each of performanceFocussedFuelInjector and superiorTransmissionDesign repective CAD file locations are assigned. economyVehicle only has a design for a fuelEfficientEngine.
