document: Authoring and annotation of web pages in CREAM Richly interlinked , machine-understandable data constitute the basis for the Semantic Web . We provide a framework , CREAM , that allows for creation of metadata . While the annotation mode of CREAM allows to create metadata for existing web pages , the authoring mode lets authors create metadata -- almost for free -- while putting together the content of a page . As a particularity of our framework , CREAM allows to create relational metadata , i.e. metadata that instantiate interrelated definitions of classes in a domain ontology rather than a comparatively rigid template-like schema asm Dublin Core . We discuss some of the requirements one has to meet when developing such an ontology-based framework , e.g. the integration of a metadata crawler , inference services , document management and a meta-ontology , and describe its implementation , viz . Ont-O-Mat , a component-based , ontology-driven Web page authoring and annotation tool .
