Provenance Metadata for Shared Product Model Databases

Abstract: The process of saving metadata committed to track all changes to some data, is known as ""provenance"". In the AEC/FM sector provenance data can be exploited for tracking all interactions of different users between each other and with parts of data. For a particular application, we need to consider which metadata are essential for future queries and who is going to use these. The IFC standard already contains some provenance concepts in its entity structure. We have considered these provenance concepts to build a provenance tracking software. The provenance ontology server was developed by using the OWL ontology language, already available IFC concepts and some complementary concepts that we had to include for the sake of generality of our implementation. The developed prototype allows us to upload an IFC file to a web enabled service that parses it and saves instances of retrieved concepts for later queries, according to the ontology we have defined.""
