<h2 id="about">The "Philosophy" of the LogValidator</h2>
<h3>Step-by-step quality</h3>
<p>
Log Validator is a web server log analysis tool with focus on the quality of Web documents.
Thanks to a modular, extensible design, the Log Validator can help Web authors find the most
popular content on their web site that matches particular criteria.</p>
<p>
The Log Validator was first written with Validation (HTML, etc.) in
mind : it can thus help web content managers find and fix the most
frequently accessed invalid documents on their Web site, acting as a
comprehensive, <a href="/QA/2002/09/Step-by-step">step-by-step</a>
validation tool.</p>
<h3 id="whatitdoes">What this tool does (and does not)</h3>
<p>This tool takes a web server's last logs and processes it through <em>validation
modules</em>. Those <em>validation modules</em> check the most popular documents'
validity for a certain technology . The default module is HTML validation, but there
are others available (see the <a href="API#modules-list">list of modules</a> for
supported technologies).</p> <p>The (X)HTML validation module, for example, helps you
find, among the most popular pages on your site, which are invalid, and thus tell you
which (invalid) pages you should fix first. This is a step-by-step process, you can
set up this tool to run every week, and painlessly fix only a few documents at the
time. Eventually, you will have fixed your whole site, or at least the most important
parts of it. (see also <a href="http://www.w3.org/QA/Tools/LogValidator/Manual#tips">
tips</a> for the HTML module)</p>
<h2 id="bgd">A bit of History</h2>
<p>Since 1994 and the <a href="http://lists.w3.org/Archives/Public/www-html/1994Jul/0015">
first HTML validator service</a>, there has been a way to check the validity of one's
webpage with regards to web standards (HTML, CSS, ...). Other services, like
<a href="http://www.w3.org/People/Raggett/tidy/">HTML Tidy</a> allow you to
(semi-)automatically fix invalid documents...</p>
<p>This tool is here to make your life as a webmaster, web designer, web developer even
easier, by telling you which documents you should fix in priority.</p>
<p>It has first been developed by <a href="/People/Gerald/">Gerald Oskoboiny</a> as
an internal W3C tool (yes, even at W3C we create invalid HTML sometimes) to check the
HTML validity of the webpages on <a href="http://www.w3.org/">the W3C website</a>, then
<a href="http://lists.w3.org/Archives/Public/www-qa/2001Sep/0031.html">released its code</a>
in september 2001.</p>
<p>In 2002, the <a href="/QA">Quality Assurance</a> team at W3C decided to re-write
it as a modular, portable, and easy-to-use tool for webmasters. Its development continues, mostly
with the addition of new processing modules making the Log Validator a very useful and versatile
Web Quality analysis tool.</p>
