From our point of view the Semantic Web stack currently is used as follows: (cf. Fig. 1):
The Semantic Web Stack with Multimedia Metadata and Web Service descriptions

Where (from bottom up):
* The two lowest layers, i.e. Unicode for a platform-neutral encoding and XML for the platform-neutral document representation are common to all (Semantic) Web applications
* Above the XML layer we have a rough distinction in the multimedia aspect and the Web Service aspect:
o On the Semantic Web/Multimedia tower we have both MPEG-7 and RDF/OWL for representing low and high-level features, possibly extended by rules
o On the Semantic Web/Services tower we have either the RDF/OWL/OWL-S-based branch or the WSML-based branch, both grounded on WSDL, again possibly using rules on the highest level.
The Semantic Web is expected to provide more benefits to software engineering. Over the past five years there have been a number of attempts to bring together languages and tools, such as the UML, developed for Software Engineering with Semantic Web langu

Web Ontology Language (OWL) is a markup language for publishing and sharing data using ontologies on the Internet. OWL is a vocabulary extension of the Resource Description Framework (RDF) and is derived from the DAML+OIL Web Ontology Language (see also D

This document is written for readers who want a first impression of the capabilities of OWL. It provides an introduction to OWL by informally describing the features of each of the sublanguages of OWL.
