A Use Case Study on provenance-based Data Assessments for Mission Critical Software Systems

Abstract

Assessments about the quality, reliability, and trustworthiness of data used and generated in mission critical software systems are important. As an example, the Backbone Catalogue for Relational Debris information (BACARDI) provides a database related to orbit information about active and inactive objects in Earth’s orbit. For the products generated by BACARDI, external data from multiple sources are necessary. At the same time, legal frameworks necessitate clear attribution of data and data products to its original contributors. The data products of BACARDI are exported and used for satellite operations like e.g., collision warnings, for mission planning, and for other mission critical applications. Hence, it is necessary to address the needs of these mission critical systems, to ensure correct data attribution and valid products. This is achieved by recording provenance of BACARDI`s data generation processes.
