There are numerous approaches to ontology-based markup (Handschuh
and Staab,2003a).As an illustration,consider how semantic markup is done
according to the CREAM framework (Handschuh and Staab,2002; 2003b).
The framework is suitable for both annotation of existing Web pages and
content annotation while authoring a Web page.The key concept in the
CREAM framework is relational metadata,i.e.metadata that instantiate
interrelated definitions of classes in a domain ontology.More precisely,for
different instantiations of classes and properties in an ontology there may
exist several semantic relationships; relational metadata are annotations that
contain relationship instances.The annotations are represented as XML
serialization of RDF triplets and are attached to HTML pages as in the
hypothetical and simplified example shown in Figure 2-18.Assume a Web
contains information about the Unplugged album by Eric Clapton,whose
homepage is at http://www.ericcIapton.com/.Assume also that the Musician
ontology sketched in Figure 2-2 is implemented in OWL and used to
annotate the two Web pages.Furthermore,let two namespaces be defined as:
