Purpose

The purpose of the Authentic Chained Data Container (ACDC) Task Force is to help draft and incubate a family of IETF-focused specifications that define the standard requirements for the semantics of Authentic Chained Data Containers. The semantics of ACDCs 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) with 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. These are all encapsulated into the semantics with the supporting syntax of an ACDC.
