Web standards are the formal, non-proprietary 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.〔(【引用サイトリンク】 title=Mission - Web Standards Project )〕 ==Overview== Web standards include many interdependent standards and specifications, some of which govern aspects of the Internet, not just the World Wide Web. Even when not web-focused, such standards directly or indirectly affect the development and administration of web sites and web services. Considerations include the interoperability, accessibility and usability of web pages and web sites. Web standards, in the broader sense, consist of the following: * ''Recommendations'' published by the World Wide Web Consortium (W3C)〔(【引用サイトリンク】title=W3C Technical Reports and Publications )〕 * ''Request for Comments'' (RFC) documents published by the Internet Engineering Task Force 〔(【引用サイトリンク】title=IETF RFC page )〕 * ''Standards'' published by the International Organization for Standardization (ISO) 〔(【引用サイトリンク】title=Search for World Wide Web in ISO standards )〕 * ''Standards'' published by Ecma International (formerly ECMA) 〔(【引用サイトリンク】 title=Ecma formal publications )〕 * ''The Unicode Standard'' and various ''Unicode Technical Reports'' (UTRs) published by the Unicode Consortium 〔(【引用サイトリンク】 title=Unicode Technical Reports )〕 * Name and number registries maintained by the Internet Assigned Numbers Authority (IANA) 〔(【引用サイトリンク】 title=IANA home page )〕 Web standards are not fixed sets of rules, but are a constantly evolving set of finalized technical specifications of web technologies. Web standards are developed by standards organizations—groups of interested and often competing parties chartered with the task of standardization—not technologies developed and declared to be a standard by a single individual or company. It is crucial to distinguish those specifications that are under development from the ones that already reached the final development status (in case of W3C specifications, the highest maturity level). 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Web standards」の詳細全文を読む スポンサード リンク
