The Gravity Data Ontology: Laying the Foundation for Workflow-Driven Ontologies
Source: University of Oklahoma
A workflow-driven ontology is an ontology that encodes discipline-specific knowledge in the form of concepts and relationships and that facilitates the composition of services to create products and derive data. Early work on the development of such an ontology resulted in the construction of a gravity data ontology and the categorization of concepts: "Data," "Method," and "Product." "Data" is further categorized as "Raw Data" and "Derived Data," e.g., reduced data. The relationships that are defined capture inputs to and outputs from methods, e.g., derived data and products are output from methods, as well as other associations that are related to workflow computation. This paper describes the construction of a workflow-driven ontology that documents the methods and processes associated with gravity data and related products.
