SeMantic Annotation enviRonmenT for Linked Services

Smart Link is short for "SeMantic Annotation enviRonmenT for Linked Services". Simply put, it is an easy-to-use Web application aiding users in the creation of Linked Services - semantic service annotations following Linked Data (http://linkeddata.org/) principles. Amongst other things, it provides an interface to populate and query the Linked Services repository iServe (http://iserve.kmi.open.ac.uk).

SmartLink builds on existing technologies and standards to enable wide reach of its annotations. Users can annotate arbitrary services - whether REST-ful or WSDL/SOAP-based - via a simple Web form. Annotations are stored in RDF following established service schemas, namely WSMO-Lite (http://cms-wg.sti2.org/TR/d11/) and the Minimal Service Model (MSM, http://iserve.kmi.open.ac.uk/wiki/index.php/Simple_vocabulary) which follow a light-weight approach to Semantic Web Services. Storage of annotations is spread across two public RDF-stores: iServe (http://iserve.kmi.open.ac.uk) handles all functional properties defined in the MSM schema while an additional and SmartLink-specific SESAME repository hosts further non-functional service properties. A unified interface to store and query annotations across both repositories is provided by SmartLink.
