slide17
CSS
  • Short for Cascading Style Sheets, a feature added to HTML that gives both Web site developers and users more control over how pages are displayed. With CSS, designers and users can create style sheets that define how different elements, such as headers and links, appear. These Style Sheets can then be applied to any Web page.
slide18
PNG
  • Portable Network Graphics - A file format for bitmapped graphic images approved by the World Wide Web Consortium as a replacement for GIF files. GIF files use a patented data compression algorithm; PNG is patent- and license-free.
slide19
RDF
  • A set of rules (a sort of language) for creating descriptions of information, especially information available on the World Wide Web. RDF could be used to describe a collection of books, or artists, or a collection of web pages as in the RSS data format which uses RDF to create machine-readable summaries of web sites.
slide20
XML
  • Extensible Markup Language is a W3C initiative that allows information and services to be encoded with meaningful structure and semantics that computers and humans can understand. XML is great for information exchange, and can easily be extended to include user-specified and industry-specified tags.

Here are just a few reasons:
but why do they listen to the w3c
But why do they listen to the W3C?
  • Because a standards body is the only way to keep internet technologies from being fragmented.
  • It is better for customers and users of the internet.
  • Because they are members.
but why do they want to members
But why do they want to members?
  • Communication, project management, accounting, advertising, and security.
  • Web technologies are the very heart of many organizations.
  • Companies need that part of their organization to be stable, and want to have a say in how it evolves.
why not the ietf
Why not the IETF?
  • When Tim Berners-Lee took HTML to the IETF it didn’t work out.
  • The IETF has traditionally been for “lower middle-ware.”
  • Its method for standards is thorough but not very efficient.
  • Practical for critical low level standards, but not for upper level standards.
