What Does ODRL Mean? A Cross-Level Ontological Grounding of Permissions, Prohibitions, and Duties in UFO-L

Summary

ODRL policy evaluators currently provide verdicts without detailing the normative positions, authority structures, or power dynamics related to norm violations. This analysis introduces the Cross-Level Design Principle, asserting that any normative language with violable, consequential norms requires both conduct-level (Permission, Duty, Right, No right) and competence-level (Power, Subjection, Immunity, Disability) positions. Applying this to ODRL, the work establishes that prohibition is sanctioned, permission is underspecified regarding its behavior parameter, and formal semantics cover only achievement obligations. By grounding ODRL in UFO-L, the framework extends coverage from two to eight legal positions, making violation-declaration authority an explicit Power-Subjection pair. All axioms were mechanically verified in Isabelle/HOL and across a 39-problem benchmark using Vampire, E, and Z3.

Key takeaway

For AI Scientists designing or evaluating normative systems, understanding ODRL's ontological limitations is crucial. You should consider incorporating a cross-level grounding approach, like that with UFO-L, to explicitly define competence-level positions such as Power and Subjection. This ensures your systems accurately model authority structures and the consequences of norm violations, moving beyond mere verdict generation to a complete representation of legal positions.

Key insights

ODRL requires a cross-level ontological grounding to fully capture normative positions and authority structures for violable, consequential norms.

Principles

• Any normative language with violable, consequential norms needs conduct-level and competence-level positions.
• Prohibition in ODRL is sanctioned, while permission is underspecified.

Method

Ground ODRL in UFO-L by mapping activated rules to simple legal relators, extending coverage from two to eight legal positions.

In practice

• Explicitly define violation-declaration authority as a Power-Subjection pair in normative systems.
• Verify normative axioms mechanically using tools like Isabelle/HOL, Vampire, E, and Z3.
