    > originalmodel.n3
    We are using the RDF file that can be found on http://linkedbuildingdata.net/tools/tool-ifc-to-rdf-conversion-tool/ and that follows the first ontology (OWL DL1).
    
    > originalmodel.rdf
    This is the same RDF model, but converted into RDF/XML notation (using RDF translator: rdf-translator.appspot.com).
    
    > conversionrules.n3
    These are the rules that allow to generate an alternative perspective on (a part of) the IFC model, a kind of simple and custom model view definition (MVD).
    
    > query.n3
    The query file is exactly the same as the conversionrules.n3 file. Using this file as a query file, the EYE reasoning engine is able to retrieve only the elements that are represented by the query file (see procedure below).
