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 HTML, CSS and JavaScript. The HTML should also meet accessibility and semantic guidelines. Full standard compliance also covers proper settings for character encoding, valid RSS or valid Atom news feed, valid RDF, valid metadata, valid XML, valid object embedding, valid script embedding, browser- and resolution-independent codes, and proper server settings.
When web standards are discussed, the following publications are typically seen as foundational:
- Recommendations for markup languages, such as Hypertext Markup Language (HTML), Extensible Hypertext Markup Language (XHTML), Scalable Vector Graphics (SVG), and XForms, from W3C.
- Recommendations for stylesheets, especially Cascading Style Sheets (CSS), from W3C.
- Standards for ECMAScript, more commonly JavaScript, from Ecma International.
- Recommendations for Document Object Models (DOM), from W3C.
- Properly formed names and addresses for the page and all other resources referenced from it (URIs), based upon RFC 2396, from IETF.
- Proper use of HTTP and MIME to deliver the page, return data from it and to request other resources referenced in it, based on RFC 2616, from IETF.
Web accessibility is normally based upon the Web Content Accessibility Guidelines 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 (OWL).

Famous quotes containing the words common and/or usage:
“If common sense had been consulted, how many marriages would never have taken place; if uncommon or divine sense, how few marriages such as we witness would ever have taken place!”
—Henry David Thoreau (1817–1862)
“I am using it [the word ‘perceive’] here in such a way that to say of an object that it is perceived does not entail saying that it exists in any sense at all. And this is a perfectly correct and familiar usage of the word.”
—A.J. (Alfred Jules)
