The Semantic Annotations API (sapience) comprises libraries giving application developers a simple and fast way to extend their applications with semantic functionality. Existing applications with complex and data models usually lack ways to describe the meaning of the data, which unnecessarily impairs the exchange of data across different applications. This is especially the case for Web services serving arbitrary content which have to be integrated into other applications. Due to our background in Geoinformatics, the libraries have a strong focus on supporting the annotation of geospatial content compliant to standards published by the Open Geospatial Consortium (OGC). The various libraries have been either developed within scientific research projects, or are results of thesis implementations (ranging from BSC to PhD). The implementations have been refactored and simplified for sapience.
The semantic annotations proxy is a free Web service enabling the semantic annotation of existing Web services using semantic standards such as SAWSDL. The proxy dynamically injects references into XML-based metadata, without the need for the service provider to create the annotations for himself. Try it out here: http://semantic-proxy.appspot.com/
