\subsection{Role within the VO architecture}

The IVOA Provenance Data Model is structuring and adding metadata to trace the processes of the astronomical data production and dissemination. Even if it borrows the main general concepts from data management science, it binds to the specific context of astronomical metadata description and re-uses or interacts with existing IVOA models. It takes benefits from existing IVOA notations and standards like UCD (semantic tags), VOUnits (standard expression of units for the VO) and service design; and it is planned for a full integration into the VO landscape.
