Abstract
This document presents definitions for the 'wp:' (white pages) and
'yp:' (yellow pages) abstract services.
1. Introduction
In "Advertising Services" [1], several abstract services are
proposed. As specified in [2], the "wp:" (white pages) and "yp:"
yellow pages abstract services are documented here.
2. The "wp" Abstract Service
The "wp" abstract service is for locating people via directory or
"white pages" services. Version 0.0 of this service specifies four
protocols for accessing such services: LDAP, WHOIS++, CCSO/Ph and
HTTP.

3. The "yp" Abstract Service
To locate resource on the Internet, a client would use the "Yellow
Pages" service and version 0.0 of the "yp" abstract service specifies
two protocols for accessing such services: Z39.50 and HTTP.
