    dct:description "The NIST Digital Manufacturing Certificate (DMC) Toolkit is a toolkit designed specifically to provide certification -- digital signature using software and hardware certificates, and verification -- of manufacturing related product data. In its first release, the DMC toolkit supports signature and validation of data in the following formats: ISO 10303-21 (STEP), ISO 6983 (G-code), ISO 32000 (PDF) and 14739 (PRC, aka 3D PDF), and Quality Information Framework (QIF). The software offers both the Toolkit as a C# API and a fully-functional demonstration application. A use case and detailed description of the technology is available in an article titled, \"Embedding X.509 Digital Certificates in Three-Dimensional Models for Authentication, Authorization, and Traceability of Product Data,\" published in the Journal of Computing and Information Science in Engineering (doi:10.1115/1.4034131)" ;
