font-family:Arial'>There is the potential for a variety of Semantic Web applications
to use specifically marked up data on HTML web pages as instances of classes or
properties expressed in RDF/OWL ontologies. This class of Semantic Web
applications would not require, or expect, the RDF/OWL ontologies to be
embedded on the HTML page along with the marked up instance data. The RDF/OWL
ontologies (.rdf or .owl files) would be located elsewhere on the Web; however,
their location (URI) would be identified as part of the instance data mark up. <o:p></o:p></span></font></p>

<p class=MsoNormal><font size=3 face=Arial><span style='font-size:12.0pt;

OWL Web Ontology Language Guide: <font color=red><span style='color:red'><a

<p class=MsoNormal><font size=3 face=Arial><span style='font-size:12.0pt;
font-family:Arial'>An HTML web site developer might want to identify selected
data on his/her web page as being instances of classes or properties of the
Wine Ontology. The following sentence might appear on the person’s web
page. “Jason Pahlmeyer created a California Bordeaux wine called the <font

The terms, arbitrarily shown in red, are the data the developer wishes to formally
associate as instances of classes or properties of the Wine Ontology. The
specific desired HTML to Ontology associations are illustrated below.<o:p></o:p></span></font></p>
