Evidence structures can vary making appraisals challenging for Verifiers. Verifiers need to understand Evidence encoding formats and some of the Evidence semantics to appraise it. Consequently, Evidence may require format transformation to an internal representation that preserves original semantics. This document specifies Evidence transformation methods for DiceTcbInfo, concise evidence, and SPDM measurements block structures. These Evidence structures are converted to the CoRIM internal representation and follow CoRIM defined appraisal procedures.}, }
