Introduction

This ontology relates the concept of wreq:Workflow, representing a Scientific Workflow, to a wreq:ExecutionEnvironment defining its dependencies. Depending on whether the steps of the workflow are fully specified in terms of infrastructure or not we distinguish between wreq:ConcreteWorkflow and wreq:AbstractWorkflow.

These concepts are related with the wreq:requiresExecutionEnvironment object property, which extends the terms:requires. For the purpose of describing the execution infrastructure we consider that a wokflow can be composed of several subworkflows, defining each one of them their own infrastructure description. We do not describe the execution order of these workflows or their inner steps.

This ontology extends some of the concepts of the p-plan ontology. Concretely the p-plan:Plan and p-plan:Step classes and the p-plan:isStepOfPlan object property.

The taxonomy of this ontology is depicted in Fig. 1. For more information about the classes and properties of the ontology check the following sections.
