The "Core Assessment Vocabulary" (CAV) is used to represent, express and define what an ""Assessment" of Assets" is and how to perform assessments based on "Criteria", regardless of the domain of the assets to be evaluated. It is the basis of the European Commission's "Common Method for Assessment of Standards and Specifications" (CAMSS), so CAV defines the conceptual models used by CAMSS and the rules and constraints specific to the CAMSS domain.
