Data Product Metadata Management: An Industrial Perspective

Decentralised data exchanges are promising alternatives to monolithic data lakes and warehouses which are typically emerging around complex service solutions. In theory, this removes some of the bottlenecks of traditional data management solutions. In practice, the road towards achieving such goal is a long way ahead. In this work, we provide an industry perspective on the implications for such work, with a focus on metadata management; the work in question draws from an invivo action research approach we enacted at a major German automotive company that is transitioning to an internal decentral data market. Our results provide insight into an industry perspective on the requirements for metadata management. Additionally, we propose and validate a solution design for metadata management in decentralised data exchanges based on semantic web service technology.
