Axis-Aligned Semantics for ODRL: Resolving Dimensional Ambiguity in Policy Constraints

arXiv:2602.19878v3 Announce Type: replace Abstract: The Open Digital Rights Language (ODRL) represents policy constraints as triples of a left operand, an operator, and a value. Several spatial operands, however, range over multi-axis domains such as width, height, and depth, while the constraint syntax provides no explicit axis identity. As a result, policy engines cannot determine whether multiple constraints apply to the same axis or different ones, making conflict detection unsound or incomplete. We resolve this ambiguity by axis decomposition, replacing multi-axis operands with axis-speci

Why this matters
Why now

The increasing complexity of digital rights management and policy enforcement, particularly in multi-dimensional data spaces, necessitates clearer semantic definitions for robust AI systems.

Why it’s important

This development improves the reliability and soundness of policy enforcement in distributed digital environments, crucial for AI systems that operate under complex legal and contractual frameworks.

What changes

Policy engines can now definitively resolve ambiguity in multi-axis spatial constraints, leading to more accurate conflict detection and policy application.

Winners
  • · Developers of digital rights management (DRM) systems
  • · Organizations enforcing complex data usage policies
  • · AI systems requiring precise policy interpretation
Losers
  • · Systems reliant on ambiguous policy definitions
Second-order effects
Direct

Reduced errors and conflicts in digital rights enforcement through explicit axis identity.

Second

Improved interoperability and trust in data sharing agreements where digital rights are critical.

Third

Acceleration of secure, policy-driven data marketplaces and decentralized autonomous organizations (DAOs) using ODRL.
