&amp;lt;h1&amp;gt; Reuse &amp;lt;/h1&amp;gt;&lt;br /&gt;
&lt;br /&gt;
One of several microformats [[principles]].&lt;br /&gt;
&lt;br /&gt;
microformats [[reuse]] building blocks from widely adopted standards:&lt;br /&gt;
&lt;br /&gt;
* [http://tantek.com/presentations/20040928sdforumws/semantic-xhtml.html semantic], [http://tantek.com/presentations/2005/03/elementsofxhtml meaningful (X)HTML], i.e. [[POSH]]. See [[SemanticXHTMLDesignPrinciples]] for more details. &lt;br /&gt;
* existing microformats&lt;br /&gt;
** as a whole, e.g. use [[hcard|hCard]] for representing people&lt;br /&gt;
** in part, reusing particular semantic class names, following [[naming-principles|microformats naming principles]]&lt;br /&gt;
* well established schemas from interoperable RFCs&lt;br /&gt;
&lt;br /&gt;
In general &amp;quot;doing what already works&amp;quot; (i.e. re-use) is greatly valued over &amp;quot;changing everything and starting from scratch&amp;quot; (i.e. re-invention).&lt;br /&gt;
&lt;br /&gt;
Thus the burden of proof is always on those who wish to change or modify what already &amp;quot;works&amp;quot; to a great extent today.  One clear instance of this is microformats' re-use of existing implied schemas (based on research of real world [[examples]]) and looking at existing widely interoperable standards as a basis for vocabulary as noted above, rather than inventing new idealistic a priori schemas or inventing new terminology for concepts already named in existing formats.&lt;/div&gt;</summary>
