The World Wide Web Consortium (W3C) is an international community where Member organizations, a full-time staff, and the public work together to develop Web standards. Led by Web inventor Tim Berners-Leeand CEO Jeffrey Jaffe, W3C's mission is to lead the Web to its full potential. Contact W3C for more information.

The Common Gateway
Interface (CGI) is not scaling to meet the requirements of
today's dynamic, interactive webs. For this reason, multiple
vendors have proposed C callable APIs. These APIs allow authors to
alleviate the performance penalty of CGI, and allow tighter
integration of add-in modules. Unfortunately, this comes at the
price of complexity and portability.
This document describes a new model for extending WWW servers.
First, HTTP is captured using an interface
specification, which eliminates the ambiguities of

This document describes PNG (Portable Network Graphics), an extensible file format for the lossless, portable, well-compressed storage of raster images. PNG provides a patent-free replacement for GIF and can also replace many common uses of TIFF. Indexed-color, grayscale, and truecolor images are supported, plus an optional alpha channel. Sample depths range from 1 to 16 bits. PNG is designed to work well in online viewing applications, such as the World Wide Web, so it is fully streamable with a progressive display option.

This document, which has been prepared for the technical subcommittee of PICS (Platform for Internet Content Selection), defines a language for describing rating services.

This memo discusses appropriate handling of documents containing imagemapped images in cases where the user-agent cannot display or otherwise process inline images. Typical examples where this is so are (i) text-only browsers such as lynx, text-to-speech or braille browsers; (ii) graphical browsers with disabled image loading; or (iii) information-gathering robots that do not retrieve or process inlined image files. Because imagemapped images are processed by the user agent and a server-side process, this memo discusses requirements of both these utilities.

This document specifies level 1 of the Cascading Style Sheet mechanism (CSS1). CSS1 is a simple style sheet mechanism that allows authors and readers to attach style (e.g. fonts, colors and spacing) to HTML documents. The CSS1 language is human readable and writable, and expresses style in common desktop publishing terminology. One of the fundamental features of CSS is that style sheets cascade; authors can attach a preferred style sheet, while the reader may have a personal style sheet to adjust for human or technological handicaps.

The Joint Electronics Payment Initiative aims to bring key industry players together to assure that multiple payment protocols can operate effectively in Web applications. The concrete goal is automatable payment selection over HTTP. The first step towards this was Don Eastlake's development of the Universal Payment Preamble, which is also available as an internet-draft (draft-eastlake-universal-payment). The second is the development of an HTTP Extension Protocol to embed UPP in HTTP. The latter proposal is part of the chartered activities of the IETF HTTP WG (draft-ietf-http-pep-03).

The HyperText Markup Language (HTML) is a simple markup language used to create hypertext documents that are portable from one platform to another. HTML documents are SGML documents with generic semantics that are appropriate for representing information from a wide range of applications. This specification defines HTML version 3.2. HTML 3.2 aims to capture recommended practice as of early '96 and as such to be used as a replacement for HTML 2.0 (RFC 1866).

This document presents the architecture and design rationale behind DSig's Digital Signature Label specifications. The overall goal is to use digitally signed labels to make authenticatable assertions about standalone documents or about manifests of aggregate objects. The three basic elements, digital signatures, assertions, and manifests, are each analyzed in terms of its design, operation, data format, and distribution strategy.
