Hierarchical ORCHID Management Entity (HOME) Interfaces for Registration & Differential Access Query

This document standardizes the interfaces of an ORCHID Management Entity (OME) to allow clients to register and query with differential access an Overlay Routable Cryptographic Hash Identifier (ORCHID) such as a Hierarchial Host Identity Tag (HHIT). Existing technologies such as CBOR/JSON Object Signing & Encryption (COSE/ JOSE) and Registration Data Access Protocol (RDAP) are selected to enable widespread interoperability.
