Evaluating the X3D Schema with Semantic Web Tools

X3D has been evolving for nearly 20 years (counting the VRML era). This long period, covering a wide range of uses (Computer Aided Design, medical, Geographic Information System...) has led to a lot of possibly inconsistent or even conflicting features. By reasoning on the X3D data model, it is possible to detect such issues, list them and propose solutions. In order to allow such a study of the model, we propose a conversion of the current XML schema to an ontology and then a systematic detection of possible issues. We then categorize them and propose solutions to fix them.
