IFC model perspectives

Files

• originalmodel.n3
  This is the original IFC/RDF file that was used for the considered test case.
  
  
• 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).
  
  
• output.n3
  This is an example output file as it is produced by the EYE reasoning engine when doing the full conversion approach (see procedure below - 'doing the conversion').
  
  
• queryoutput.n3
  This is an example output file as it is produced by the EYE reasoning engine when doing the conversion by query approach (see procedure below - 'query conversion rules').
  
  
• README.txt
  Textual overview of this HTML page.
  
  
• IFCmodelperspectives_pieterpauwels.zip
  Full ZIP file including all the files above.
  
  

Procedure

Doing the conversion

1. Install EYE: see http://eulersharp.sourceforge.net/INSTALL
2. Test run EYE and see that everything is installed correctly
3. See all possible EYE commands on http://eulersharp.sourceforge.net/README
4. open command line
5. run "eye --nope originalmodel.n3 conversionrules.n3 --pass > output.n3"
6. see additional RDF statements at the end of the output.n3 file

Edit rules

1. open up conversionrules.n3 in any notepad application
2. start editing

Query conversion rules

1. Install EYE: see http://eulersharp.sourceforge.net/INSTALL
2. Test run EYE and see that everything is installed correctly
3. See all possible EYE commands on http://eulersharp.sourceforge.net/README
4. open command line
5. run "eye --nope originalmodel.n3 conversionrules.n3 --query query.n3 > queryoutput.n3"
6. find the retrieved RDF statements in the queryoutput.n3 file
