LOAMA: Low-Code ODRL Access Management Application

Wout Slabbinck, Lennert De Rouck, Joachim Van Herwegen, Wouter Termont, Beatriz Esteves, and Ruben Verborgh

State-of-the-art authorization mechanisms have so far focused on dealing with data management, while leaving policy management and enforcement as an afterthought. Considering that the latter are of the utmost importance to deal not only with low-level technical requirements, but also crucial to deal with legal or economic requirements, we introduce LOAMA, the Low-code ODRL Access Management Application, which can be used to manage ODRL policies in decentralized settings through an Authorization Server. In this paper, beyond a demonstration of the LOAMA User Interface, we provide an overview of the LOAMA architecture, which is based on the User-Managed Access (UMA) specifications. LOAMA abstracts the complexity of managing policies, by providing a tool that people not familiar with policy languages can use to manage their preferences regarding access management. Future works includes the expansion of the LOAMA UI to support further ODRL constraints, e.g., to express purpose-based or temporal usage control policies.
