Web Architecture Current Status

This page summarizes the relationships among specifications, whether they are finished standards or drafts. Below, each title links to the most recent version of a document.

Completed Work

W3C Recommendations have been reviewed by W3C Members, by software developers, and by other W3C groups and interested parties, and are endorsed by the Director as Web Standards. Learn more about the W3C Recommendation Track.

Group Notes are not standards and do not have the same level of W3C endorsement.



Architecture of the World Wide Web, Volume One

The World Wide Web uses relatively simple technologies with sufficient scalability, efficiency and utility that they have resulted in a remarkable information space of interrelated resources, growing across languages, cultures, and media. In an effort to preserve these properties of the information space as the technologies evolve, this architecture document discusses the core design components of the Web. They are identification of resources, representation of resource state, and the protocols that support the interaction between agents and resources in the space. We relate core design components, constraints, and good practices to the principles and properties they support.

Group Notes


Self-Review Questionnaire: Security and Privacy

This document lists a set of questions one could ask about the security and privacy impact of a new feature or specification. It is meant as a tool that groups or individuals can use as a guide during a self-review, pointing towards important questions in areas where expertise might be lacking.


Linked Data Glossary

The Linked Data Glossary contains terms defined and used to describe Linked Data, and its associated vocabularies and best practices related to publishing structured data on the Web using open Web standards.


Publishing and Linking on the Web

This document is intended to inform future social and legal discussions of the Web by clarifying the ways in which the Web's technical facilities operate to store, publish and retrieve information, and by providing definitions for terminology as used within the Web's technical community. This document also describes the technical and operational impact that does or could result from legal constraints on publishing, linking and transformation on the Web.


Usage Patterns For Client-Side URI parameters


Web Characterization: From working group to activity


Below are draft documents: Last Call Drafts, other Working Drafts . Some of these may become Web Standards through the W3C Recommendation Track process. Others may be published as Group Notes or become obsolete specifications.

Last Call Drafts


Best Practices for Fragment Identifiers and Media Type Definitions

This document recommends best practices for the authors of media type definitions, for the authors of structured syntax suffix definitions (such as +xml), for the authors of specifications that define syntax for fragment identifiers, and for authors that publish documents that are intended to be used with fragment identifiers or who refer to URIs using fragment identifiers.

Other Working Drafts


Good Practices for Capability URLs

Capability URLs grant access to a resource to anyone who has the URL. There are times when this is useful, for example one-shot password reset URLs, but overuse can be problematic as URLs cannot generally be kept secret. This document provides some good practices for web developers who wish to incorporate capability URLs into their applications.


URLs in Data Primer

This document addresses the issue of the mode in which a URL identifies information about the content or a description of the content by describing how to define data formats and publish the information.

Obsolete Specifications

These specifications have either been superseded by others, or have been abandoned. They remain available for archival purposes, but are not intended to be used.
