The goal of ORE is to support the process of extracting and validating OPC UA rules. Input to ORE are textual OPC UA companion specifications. ORE is then capable to extract rules from the textual OPC UA companion specifications, represent them in a suitable format, and provide mechanisms for the verification of these rules by (domain) experts, possibly in a distributed setting (e.g., allowing a team of experts to collaboratively verify such rules). Within the project ORE 2.0, the results of the predecessor project ORE will be revised, new approaches for rule evaluation will be investigated, and validated on a common use case. In parallel, ongoing activities of the Semantic Validation Working Group of the OPC Foundation will be taken into account.
