Yeah, IncA (compiling to Souffle) and Ascent (I believe Crepe is not parallel, though also a good engine) are two other relevant cites here. Apropos linked data, our group has an MPI-based engine which is built around linked facts (subsequently enabling defunctionalization, ad-hoc polymorphism, etc..), which is very reminiscent of the discussion in the first link of yours: https://arxiv.org/abs/2211.11573
