ACDC (Authentic Chained Data Container) Task Force
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.

Mailing List and Communications
This task force uses the following for communications
- Slack: This TF has its own dedicated Slack channel: #tswg-acdc-tf
- Github: This TF will use GitHub issues for substantive conversations on topics, not Slack. This way the conversation is source controlled.
Specification Generation
Specifications use the IETF draft format but may use the following:
- Markdown: Draft portions spec written in Markdown
- SpecUP: Final version of spec processed with SpecUp
Use Cases
This table lists the starting set of use cases motivating the ACDC work.
Task | Description | Link | Authors |
