The W3C has released a last call
Working
Draft of the Platform for Privacy Preferences (P3P) after
getting past a number of issues, including a patent that had been seen as threatening.
P3P 1.0 describes a set of technologies that let users determine how information supplied in a
transaction
may be used, with future development possibly leading to more sophisticated negotiation about such
policies..
It adds a new policy
header to HTTP, allowing servers to identify where information about their privacy policies may be
found, as well as new usage for the HTML LINK
element to perform a similar service without modifications to Web servers.
P3P specifies the grammar used for its policy descriptions using ABNF, but really describes an XML
vocabulary. P3P 1.0 doesn't use XLink for its links, sticking
with its own vocabulary for referencing external resources. Although RDF is often
mentioned in association with P3P, RDF is not mentioned in this draft.
Last Call ends on 30 April 2000, a much longer time than has been common in prior W3C activity.
Comments should be sent to the www-p3p-public-comments@w3.org mailing
list.
