			<content:encoded><![CDATA[<p><font size="3"></p>
<h2 align="justify" class="western"><font color="#000000"><font size="3">A Web obedecem a padrões universalmente aceitos e serão ricas em significado, algo muito diferente da Web do passado em que as páginas eram construídas de forma desorganizada e eram difíceis de entender e de manter. Para compreendermos aquilo que torna possível dar significados claros aos conteúdos das páginas e dar eficiência à publicação na Web, precisamos de saber o que é a Web Semântica. </font></font></h2>
<p align="justify" style="text-indent:1cm;font-style:normal;text-decoration:none;" class="western"><font size="3"><font color="#000000"><strong>O objectivo é melhorar as potencialidades da Web através da criação de ferramentas e de padrões que permitam atribuir significados claros aos conteúdos das páginas e facilitar a sua publicação e manutenção. </strong></font></font></p>
<p align="justify" style="text-indent:1cm;font-style:normal;text-decoration:none;" class="western"><font color="#000000"><font size="3"><strong>As páginas construídas usando Web Semântica passam a fazer parte de um meio universal para a troca de informação. Trata de um meio universal porque estas páginas podem ser lidas por humanos ou por máquinas e tanto podem ser apresentadas graficamente, ou como lidas em voz alta por browsers capazes de sintetizar voz e podem ser apresentadas em telefones móveis adequados. </strong></font></font></p>
<p align="justify" style="text-indent:1cm;" class="western"><span><span style="text-decoration:none;"><span style="font-style:normal;"><font size="3"><font color="#000000"><strong>O elementos da linguagem HTML têm significados claros, existindo elementos para definir </strong></font></font></span></span></span><a href="http://www.artifice.web.pt/tutoriais/cntd/tut_html4.html#a4_2"><span><span style="text-decoration:none;"><span style="font-style:normal;"><font size="3"><font color="#000000"><strong>cabeçalhos</strong></font></font></span></span></span></a><span><span style="text-decoration:none;"><span style="font-style:normal;"><font size="3"><font color="#000000"><strong>, </strong></font></font></span></span></span><a href="http://www.artifice.web.pt/tutoriais/cntd/tut_html4.html#a4_3"><span><span style="text-decoration:none;"><span style="font-style:normal;"><font size="3"><font color="#000000"><strong>parágrafos</strong></font></font></span></span></span></a><span><span style="text-decoration:none;"><span style="font-style:normal;"><font size="3"><font color="#000000"><strong>, </strong></font></font></span></span></span><a href="http://www.artifice.web.pt/tutoriais/cntd/tut_html7.html#a7"><span><span style="text-decoration:none;"><span style="font-style:normal;"><font size="3"><font color="#000000"><strong>listas</strong></font></font></span></span></span></a><span><span style="text-decoration:none;"><span style="font-style:normal;"><font size="3"><font color="#000000"><strong>, etc. Se usarmos corretamente os elementos do HTML as estruturas das páginas que escrevemos serão claras e fáceis de compreender. </strong></font></font></span></span></span></p>
<p align="justify" style="text-indent:1cm;font-style:normal;text-decoration:none;" class="western"><font size="3"><strong>Se quisermos que as páginas que escrevemos tenham um aspecto sofisticado então temos de formatá-las. O objectivo da Web Semântica é que ao acrescentarmos a formatação nós não causemos a destruição da semântica do HTML. </strong></font></p>
<p align="justify" style="text-indent:1cm;" class="western"><font size="3"><span style="text-decoration:none;"><span style="font-style:normal;"><strong>O objectivo da Web Semântica é permitir fazer formatação das páginas com grande liberdade sem interferir com os significados dos elementos do HTML. Na sua forma mais simples a estratégia recomendada consiste em fazer com que a informação seja guardada em páginas escritas em HTML ou XHTML e o aspecto final da apresentação seja definido através de estilos CSS.</strong></span></span></font></p>
