Designing a Visual Tool for Property Graph Schema Extraction and Refinement: An Expert Study

Abstract: The design space of visual tools that aim to help people create schemas for property graphs is explored. Interviews are conducted with experts in the domain of property graphs and data management in general. Through this collaboration, we determine how a schema extraction tool can provide value. These insights are used to establish design requirements and design a UI prototype, which are then relayed back to the experts. Positive reactions were received, which encourage future work in the property graph schema space.
