Extending Content Management Systems with Ontological Annotation Capabilities

Producing semantic metadata requires efficient methods, e.g., concept finding, for accessing and using ontologies. To add such functionalities to metadata applications such as cataloging systems in museums, we propose a mash-up approach where ready-to-use user interface components for using specific ontologies are made available to be integrated into applications. As a proof-of-concept, we present the Ontology Service ONKI wich implements semantic autocompletion concept search and concept browsing for ontologies as shared mash-up components.
