An apparatus provides computing sources of functionality, each computing source of functionality presents a service and exists in any computing environment of the apparatus. The apparatus associates a semantic service description (SSD) with the service. The SSD has a semantic description of the service, including a semantic description of a parameter of the service, according to a computer interpretable language, and, as a service grounding, a mapping between the computer interpretable language expressing the SSD and an interface, including an interface parameter, of the service. The apparatus dynamically discovers SSDs as available services through discovery mechanisms, filters the services based upon the semantic description in each SSD associated with each service, generates a user interface to dynamically compose a task based upon selecting the services and the filtering the services to continuously present possible tasks, and generates an executable semantic service workflow description of the composed task.
