Purpose
The purpose of the Authentic Chained Data Container (ACDC) Task Force is to draft a family of ToIP Specifications that defines the standard requirements for the semantics of Authentic Provenance Chaining of Authentic Data Containers. This semantics include both source provenance and authorization provenance or delegation. The hypothesis is that the W3C Verifiable Credential standard may be expanded to serve as an Authentic Data Container (ADC) and that the semantics of a VC may be expanded to support an authentic provenance chains (APC) as a super semantic. This may be further expanded to support both a source provenance sub-semantic and a delegated authorization sub-semantic.
