Towards Provenance and Traceability in CRISTAL for HEP
This work addresses provenance and traceability challenges for physicists and researchers in High Energy Physics, but it appears incremental as it builds on existing CRISTAL uses without introducing major new methods.
The paper discusses the CRISTAL object lifecycle management system for provenance data management and traceability of system events in High Energy Physics, highlighting its use in projects like CMS ECAL detector construction and outlining initial ideas for data preservation applications.
This paper discusses the CRISTAL object lifecycle management system and its use in provenance data management and the traceability of system events. This software was initially used to capture the construction and calibration of the CMS ECAL detector at CERN for later use by physicists in their data analysis. Some further uses of CRISTAL in different projects (CMS, neuGRID and N4U) are presented as examples of its flexible data model. From these examples, applications are drawn for the High Energy Physics domain and some initial ideas for its use in data preservation HEP are outlined in detail in this paper. Currently investigations are underway to gauge the feasibility of using the N4U Analysis Service or a derivative of it to address the requirements of data and analysis logging and provenance capture within the HEP long term data analysis environment.
