the global Internet's systems of unique
identifiers and in particular, ensuring its
stable and secure operation

The World Wide Web Consortium
(W3C)

member
organizations, a full

staff, and the
public work together to develop

web
standards. Led by web inventor

Tim
Berners

mission is to lead the web to its full
potential.

The Web Services Interoperability
Organization (WS

I)

an open industry organization chartered to
establish best practices for web services
interoperability, and selected groups of web
services standards, across platforms
operating systems

and programming
languages.

The Web Services Interoperability

Web standards

are the formal,

non
-
proprietary


standards

and other
technical

specifications

that define
and describe aspects of the World
Wide Web



Standards

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.

Specifications

Web
s
tandards are call specification. They
are developed by comities and groups and
often take a long time as there is a lot of
discussion on what each element should
look like. A standard starts out as a
“PROPOSED” standard and then is
published to a “RECOMMENDED” standard

There are many benefits in having a
webpage conform to current standards
and best practices.




Better accessibility


More complete understanding by search
engines


More interoperability with other software
tools


Increased conformity across web
browsers


HTML Specification


HTML 4.01 is the current specification and
was published in 1999.



HTML5 is on course to be the new HTML
specification with a scheduled release in
2014

CSS Specification


CSS2 was published in May 1998


CSS2.1 was a revision shortly after that


CSS3 specification is still under
development by W3C. However, many of
the new CSS3 properties have been
implemented in modern browsers.


Publishing

Generally when we think of webpages and
where they reside world wide web, we think
of on a hosting web server

Publishing

What is a web Server?


Servers like web server, email servers, FTP
servers and others are actually software
packages designed to serve up there
specific application type files.

Publishing

A server is not specifically a computer. One
computer can run many servers.

For example: a “SERVER” computer may
run Web, Email and FTP servers all at once.

Publishing

Servers are software packages that live on
a dedicated computer. Usually these
computers are much higher in performance
than the desktop pc or they may even be an
entire bank of computers. It is the software
package and the computer that we
collectively call “SERVER”

Publishing

FTP

File transfer protocol is the main method of
publishing Webpages. The main reason for
this is that the majority of the time web
developers are not on the same network or
same computer as the web server, so the
finished web page must be moved over the
internet to the intended server

FTP Tools


Often Integrated design environments
such as Dreamweaver have an internal
FTP client



Filezilla is an example of a standalone
FTP client



Windows Directory FTP is also a very
useful tool fro publishing webpages

Publishing

Network

If a web developer is working on the same
network as the webserver or on the same
computer as the webserver then web pages
could be published without FTP with a
simple file share or network save. This less
common than normal

Conclusion


ICANN is the organization for assigning IP
addresses


W3C is the organization for establishing
web specifications


Standards help with accessibility and
interoperability

Conclusion


HTML4.01 is the current HTML
specification as of 1999


HTML5 is the expected next HTML
standard with a due date of 2014


CSS2.1 is the current CSS specification
as of 1998


CSS3 is the expected next CSS standard
with a due date of 2014


Conclusion


FTP is a protocol for publishing Webpages
to the web server


FTP can be used in a variety of
applications such as the GUI
-
IDE, stand
alone clients,
FTP Windows
