Separate Compilation and Partial Linking: Modules for Datalog IR

In recent years, Datalog has sparked renewed interest in academia and industry, leading to the development of numerous new Datalog systems. To unify these systems, recent approaches treat Datalog as an intermediate representation (IR) in a compiler framework: Compiler frontends can lower different Datalog dialects to the same IR, which is then optimized before a compiler backend targets one of many existing Datalog engines. However, a key feature is missing in these compiler frameworks: an expressive module system.
