DLite - a lightweight data-centric framework for semantic interoperability

Documentation and resources on semantic interoperability efforts at Health-RI.

Shared canonical names for agent-governance primitives. Maps what each system calls its signals to one reference vocabulary, with per-system crosswalks, so verifiers and tooling compose across ecosystems.

This is a repository for the two use cases described in the Association for Information Science and Technology (ASIS&T) 2017 annual conference paper: Agreeing to disagree: reconciling conflicting taxonomic views using a logic-based approach.
