<a name="Overview" id="Overview"></a><h2> <span class="mw-headline"> Overview </span></h2>
<p>POWDER provides a mechanism to describe and discover Web resources and provide a succinct way to define any number of predicates for those resources. POWDER is designed to facilitate incorporation of information in larger RDF-based systems.
</p><p>There are a variety of use cases: from providing a better means to describing Web resources and creating trustmarks to aiding content discovery, child protection and Semantic Web searches, describing copyright or licensing information to a family of resources.
