SADI

SADI - Semantic Automated Discovery and Integration - is a lightweight set of fully standards-compliant Semantic Web service design patterns that simplify the publication of services of the type commonly found in bioinformatics and other scientific domains. SADI Services utilize Semantic Web technologies at every level of the Web services "stack". Services are described in OWL-DL, where the property restrictions in OWL Classes are used to define the properties expected of the input and output data. Invocation of SADI Services is achieved through HTTP POST of RDF data representing OWL Individuals ('instances') of the defined input OWL Class, and the resulting output data will be OWL Individuals of the defined output OWL Class.
