W3C Standards Support in IE and the Netscape Gecko Browser Engine
|
|
|
|
<p>
|
|
"The underlying technology of the web browser has reached the point where standards compliance must take precedence. In order for the web to maintain its bullet-train rate of innovation, the web browser must become a stable building block for site designers, just as standardization on Windows has encouraged innovation in the PC space." - David Kerley, senior analyst, Jupiter Communications
|

<p>
|
|
Why support web standards? It's pretty clear to us here at Netscape that a standards-compliant browser provides developers and end users with the following benefits:
|
|
<ul>
|
|
<li>ability to access rich web content and applications across a variety of hardware platforms and devices
|
|
<li>reduced cost for content and application development by enabling development to a single specification
|
|
<li>increased innovation by providinga rich, standards-based platform for application development
|
|
<li>freedom of choice by reducing switching costs between vendors and applications
|
|
<li>investment protection by enabling the creation of applications built on stable industry standards rather than proprietary technology subject to change </li">
|
|
<li>the preservation of vigorouscompetition between vendors by preventing vendor lock-in
|
|
</ul>
|
|
Given the demand by developers and users for web standards compliance in browsers, it's surprising to find newly-released browsers that don't adhere to published, mature web standards. Yet even brief testing reveals dramatic differences in the scope, robustness, and consistency across platforms of the W3C standards support in the latest releases of Internet Explorer and the Netscape Gecko browser engine in the Mozilla M13 milestone build. This document compares the two browsers' support for the following:
|
|
<ul>
|
|
<li><a href="#5">Document Object Model (DOM)</a>
|
|
<li><a href="#3">Extensible Markup Language (XML)</a>
|
|
<li><a href="#4">Resource Description Framework (RDF)</a>
|
|
<li><a href="#1">Cascading Style Sheets, Level 1 (CSS-1)</a>
|
|
<li><a href="#2">HyperText Markup Language 4.0 (HTML 4.0)</a>
|
|
</ul>
|
|
Netscape Gecko's robust support for W3C standards for the first time
|
|
enables the development of sophisticated, entirely standards-based applications.
|
|
Developers are already applauding this commitment to enabling the platform,
|
|
device, browser, and vendor-independent web applications of the future.
|
|
Meanwhile, industry leaders like IBM, Intel, Liberate, NetObjects, Nokia,
|
|
red Hat, and Sun Microsystems are <a

|
|
<p> As the standard itself states, the Document Object Model Level 1 provides
|
|
"a platform- and language-neutral interface that allows programs
|
|
and scripts to dynamically access and update the content, structure
|
|
and style of documents. The Document Object Model provides a standard
|
|
set of objects for representing HTML and XML documents, a standard model
|
|
of how these objects can be combined, and a standard interface for accessing
|
|
and manipulating them. Vendors can support the DOM as an interface to
|
|
their proprietary data structures and APIs, and content authors can
|
|
write to the standard DOM interfaces rather than product-specific APIs,
|
|
thus increasing interoperability on the web."

|
Robust support for
|
|
the W3C DOM is perhaps the most critical requirement for enabling the
|
|
next generation of platform and device independent web applications
|
|
that will have functionality and user interfaces equivalent to current
|
|
native applications, because it is the W3C DOM that opens up the content
|
|
and format of the page to manipulation from languages like JavaScript.
|
|
The W3C DOM, level 1 has two parts: DOM 1 Core and DOM 1 HTML. DOM 1
|
|
Core provides a crucial set of core methods for reading, writing, and
|
|
changing the content of documents on any platform or device--methods
|
|
that work equally well for HTML and XML. DOM 1 HTML provides a set of
|
|
convenience extensions that are specific to HTML documents only.
