# ACDC IPEX Negotiation (working notes, markdown)

Working design notes, longer and later than the PDF of the same name, on negotiating graduated disclosure of Authentic Chained Data Containers (ACDCs) under the Issuance and Presentation Exchange (IPEX) protocol: attribute path lists against a composed schema, closure rules by section, new unary edge operators, presentation registries, anchored exchange diagrams and an SEDI (State Endorsed Digital Identity) example. For implementers of ACDC and IPEX.

Labels: reading level Implementer; evidence informative (an author's paper, deck, tutorial or post explaining the suite).
