CREAM: CREAting Metadata for the Semantic Web

摘要

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 creation of 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 feature of our framework, CREAM allows creating relational metadata, i.e., metadata that instantiate interrelated definitions of classes in a domain ontology rather than a comparatively rigid template-like schema such as 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. OntoMat, a component-based, ontology-driven Web-page authoring and annotation tool.
