Web standards

Web standards is a general term for the formal standards and other technical specifications that define and describe aspects of the World Wide Web. In recent years, the term has been more frequently associated with the trend of endorsing a set of standardized best practices for building web sites, and a philosophy of web design and development that includes those methods.

Many interdependent standards and specifications, some of which govern aspects of the Internet, not just the World Wide Web, directly or indirectly affect the development and administration of web sites and web services. While any of these may be called “web standards,” advocates within the web standards movement tend to focus on the higher-level standards that most directly affect the accessibility and usability of web sites. Web standards, in the broader sense, consist of the following:
* "Recommendations" published by the World Wide Web Consortium (W3C)
* "Internet standard" (STD) documents published by the Internet Engineering Task Force (IETF)
* "Request for Comments" (RFC) documents published by the Internet Engineering Task Force
* "Standards" published by the International Organization for Standardization (ISO)
* "Standards" published by Ecma International (formerly ECMA)
* "The Unicode Standard" and various "Unicode Technical Reports" (UTRs) published by the Unicode Consortium
* Name and number registries maintained by the Internet Assigned Numbers Authority (IANA)

Common usage

When a web site or web page is described as complying with web standards, it usually means that the site or page has valid or nearly valid HTML, CSS and JavaScript. The HTML should also meet accessibility and semantic guidelines.

When web standards are discussed, the following publications are typically seen as foundational:
* Recommendations for markup languages, such as HTML, XHTML, SVG, and XForms, from W3C.
* Recommendations for stylesheets, especially CSS, from W3C.
* Standards for ECMAScript, most commonly JavaScript, from Ecma International.
* Recommendations for Document Object Models, from W3C.

Web accessibility is normally based upon the Web Content Accessibility Guidelines [http://www.w3.org/TR/WAI-WEBCONTENT/] published by the W3C's Web Accessibility Initiative.

Work in the W3C toward the Semantic Web is currently focused by publications related to the Resource Description Framework (RDF), Gleaning Resource Descriptions from Dialects of Languages (GRDDL) and Web Ontology Language (WOL).

People who ardently support Web standards often self-describe as "standaristas".

tandards publications and bodies

A W3C Recommendation is a specification or set of guidelines that, after extensive consensus-building, has received the endorsement of W3C Members and the Director.

An IETF Internet Standard is characterized by a high degree of technical maturity and by a generally held belief that the specified protocol or service provides significant benefit to the Internet community. A specification that reaches the status of Standard is assigned a number in the IETF STD series while retaining its original IETF RFC number.

Non-standard and vendor-proprietary pressures

In the current Editor's Draft of the HTML 5 proposed standard document [http://www.w3.org/html/wg/html5/#relationship-to-xul-flash-silverlight-and-other-proprietary-ui-languages] , the W3C has a section entitled "Relationship to XUL, Flash, Silverlight, and other proprietary UI languages" which says, "This specification is independent of the various proprietary UI languages that various vendors provide. As an open, vendor-neutral language, HTML provides for a solution to the same problems without the risk of vendor lock-in."
