Towards Compliance to Safety Objectives Using Data Curation

Summary and ConclusionsThis paper presents a methodology to show compliance to safety objectives using a new data curation system called RACK. First, we use a bowtie diagram as a lightweight safety analysis to demonstrate the connection between safety assessment and software development process. Once an assurance level is properly assigned, we use a Python script to highlight which DO-178C objectives we are obligated to show compliance to. Next, we present the use of RACK—Rapid Assurance Curation Kit—to find evidence in each of the software development processes. Finally, we present a novel way to concisely visualize traceability and status of compliance to DO-178C objectives via a sunburst. Our finding is that provenance language is embedded in DO-178C and their referenced activities. This makes RACK suitable for demonstrating compliance since its underlying data model is built on provenance classes and relationships. In summary, this paper presents a methodology that automatically generates a visualization to show compliance to DO-178C objectives using RACK to query for evidence that an activity was completed.
