Towards Semantic Provenance in CRISTAL

Traceability is an important feature of workflow based systems, and is a key source of provenance data. This paper presents CRISTAL, a mature software platform developed and used at CERN for experiment construction at the LHC. It is entirely workflow based capturing provenance on every aspect of its use from application development to end-user interaction. In this paper we summarize some initial work towards the adaptation of CRISTAL to a more semantic orientation, in particular compliance with the Open Provenance Model.
