PICS Reference Code

The W3C is committed to providing reference code, free of charge, for important components of the PICS architecture. We are actively soliciting donations of code or labor to produce code.

PICS Label Generators

• Java-based user interface by Ching Law, a tool to generate PICS label with point and click user-interface.
• PICSLE, the PICS Label Editor, is a tool under development at the IBM T.J. Watson Research Center for adding PICS labels to a PICS Label Bureau service database. Any PICS Label Bureau service description file that conforms to Rating Services and Rating Systems (and Their Machine Readable Descriptions) can be understood by PICSLE, and a variety of label output schemes are supported.
• PICS client and label parsing library code for Unix and Win32.

User Profile Editors

Sample implementations intended to demonstrate approaches for configuring content selection software, such as parent would use when installing a Web browser. The last one is intended for Internet publishers to generate PICS label with point and click user-interface.
