2167: Referral Whois (RWhois) Protocol V1.5.

This memo describes Version 1.5 of the client/server interaction of RWhois. RWhois provides a distributed system for the discovery, retrieval, and maintenance of directory information. This system is primarily hierarchical by design. It allows for the deterministic routing of a query based on hierarchical tags, referring the user closer to the maintainer of the information. While RWhois can be considered a generic directory services protocol, it distinguishes itself from other protocols by providing an integrated, hierarchical architecture and query routing mechanism.
