W3C
• The W3C (World Wide Web Consortium) is an international organization that
creates standards for the World Wide Web.
• The W3C is committed to improving the web by setting and promoting web-
based standards.
• The W3C's goal is to create technical standards and guidelines for web
technologies worldwide.
• These standards are intended to keep a consistent level of technical quality and
compatibility concerning the World Wide Web.

History
• World Wide Web Consortium was founded by Tim Berners-Lee in October 1994
at the Massachusetts Institute of Technology, with the support of
DARPA(Défense Advanced Research Projects Agency) and CERN.
• The main vision of W3C was to standardize the technologies as well as the
protocols that are used to build the web.
• It also tried to encourage the organizations to adopt the new standards defined by
the World Wide Web Consortium.
• In the next few years, the W3C thus published various recommendations such as
the format of PNG images, CSS(versions 1 and 2), etc.

Purpose of the W3C
• W3C is designed to bring interested parties together from different areas of IT to
work on developing web standards.
• The W3C also focuses on developing protocols and guidelines that help ensure
the growth and longevity of the web.
• Developing new standards is a consensus-based process by different teams in the
W3C, as these standards are intended to help ensure quality for web-based
developers and end users.

W3C standards
• W3C standards describe a range of recommended programming languages to
generally accepted principles in web services and open architectures.
• Web design and application standards are following:
Common Gateway Interface (CGI)
CSS
Document Object Model (DOM)
Extensible HTML (XHTML)
Extensible Markup Language (XML)
Gleaning Resource Descriptions from Dialects of Languages (GRDDL)
HTML
JavaScript Object Notation for Linked Data (JSON-LD)
S.Revathi AP/CSE 6
Resource Description Framework (RDF)
Simple Object Access Protocol (SOAP)
SPARQL Protocol and RDF Query Language (SPARQL)
Speech Recognition Grammar Specification (SRGS)
Speech Synthesis Markup Language (SSML)
Scalable Vector Graphics (SVG)
VoiceXML (VXML)
Web Real-Time Communications (WebRTC)
Web Services Description Language (WSDL)

Advantages
• W3C enables the easier maintenance of the W3C validated websites.
• It provides a consistent and defined look for all the W3C validated websites.
• It standardizes the validated websites so that they are accessible to different
devices.
• It enables faster browser interaction.
S.Revathi AP/CSE 8
Disadvantages
• W3C validation is a timely process and thus the time for full validation
depends on the website code.
• W3C validation exercises have costs associated with them.
• Sometimes translation issues arise in W3C validation of websites.
