component of web 3.0

Hence the web is required to be more meaningful

device and every thing will be on the cloud.

How HTML5 helps to make a semantic web

<dl><dt>Name<dt>

<dd>Mark Zuckerberg</dd><dt>Position</dt> <dd><span >Developer advocate</span> for <span>Google, Inc.<span></dd></dl>

Part of a normal webpage

How HTML5 helps to make a semantic web

<dl><dt>Name<dt>

<dd itempprop=“name”>Mark Zuckerberg</dd><dt>Position</dt> <dd><span itempprop=“title”>CEO</span> for <span itempprop=“company”>facebook</dd></dl>

Make it more meaning full…

There are lot of other elements like <article>,<section>,<summary>… helps a webpageto be more meaningful.
