Microsoft Corp, a backer of W3C World Wide Web Consortium’s P3 Platform for Privacy Preferences standard announced last month (CI No 3,180), says it will offer broad support for P3 in future product lines. P3 will be supported on the client side by Internet Explorer 4.0, the browser due for release this summer. On the server side, Microsoft will add P3 support to the Site Server electronic commerce package and to its Active Directory directory services set, due to appear in the next release, version 5.0, of Windows NT. Microsoft said it would also support P3 in its Web content and services sites such as MSNBC and the Sidewalk city guides. P3 members include Microsoft, Netscape Communications Corp, Firefly Network Inc and IBM Corp. It is based on the OPS Open Profiling Standard, submitted to the W3C by Netscape and 60 other vendors (CI NO 3,169).
