PICS Implementation Guide

Platform for Internet Content Selection (PICS)

This was originally designed to help parents and teachers control what children access on the Internet, but it also facilitates other uses for labels, including code signing and privacy. The PICS platform is one on which other rating services and filtering software have been built.’

xxx” indicates a field that must match between these files.
