Researchers have developed a new evaluator for the Open Digital Rights Language (ODRL) that provides formal mathematical semantics for policy evaluation. This addresses the current lack of standardization, which leads to inconsistent interpretations and limited interoperability among different ODRL implementations. The new evaluator offers transparent formal semantics, supports all rule types, and includes an efficient algorithm and implementation for both static and streaming data access control and monitoring scenarios. Performance evaluations have been conducted to analyze scalability with varying policy complexity and data sizes, and a comparative review highlights its advantages over existing ODRL evaluators. AI
