LTML - A Language for Representing Semantic Web Service Workflow Procedures

The Learnable Task Modeling Language (LTML) was developed by combining features of OWL, OWL-S, and PDDL, using a more compact and readable syntax than OWL/RDF to create human readable representations of web service procedures and hierarchical task models. The goal was in part to develop a more robust and developer-friendly language based on the principles and design that led to OWL-S and demonstrate that such a language also provided the basis for developing tools that could learn web service procedures by demonstration.
