- Defines the meta-model for learning service descriptions
- Uses ontologies to index and store these models
- So that students, teachers, researchers can use this model to query and publish learning services
- Facilitator [along with Ontobroker- a inference engine (to trigger various processes and events) and for ontology management (add, delete, modify ontologies)] based on ontology is developed/used for service discovery and composition. It provides the interfaces that allows the client and servers to query(import function) and advertise (import function) learning services based on underlying ontologies. If search is successful, it invokes the service selected interacting with the provider and sends the result to the client. If service search is unsuccessful, allows the services to be composed automatically.
- Their own approach for semantic description of service behavior that includes input/output flows and post/pre-conditions
- Their own approach for service interface description
