]> The Workflow-Driven Ontology Workflow-Driven Ontology Version 1.0 of the Workflow Driven Ontology. Authors: Leonardo Salayandia, Ann Q. Gates, and Paulo Pinheiro da Silva Data and dataset concepts of the domain being modeled. Data 1 1 1 1 Methods, algorithms and other functionality concepts of the domain being modeled. Method 1 1 Used to reference Semantic Abstract Workflows as first-class citizens. Workflows are considered abstract because the control flow is not formally specified. Workflow 1 Used to specify a decision point in an abstract workflow. Semantics of the decision concept are intentionally vague. Decision Used to specify a fork point in a workflow where a single incoming data concept is broadcasted to multiple outgoing branches. Broadcast Used to specify a decision point in the workflow specification where exactly one route is taken in the workflow execution. XOR Used to specify the location of an artifact in a workflow graph. RectCoord 1 1 1 Used to classify the concepts that are represented by a node in a workflow graph, and hence have a location given by a coordinate. Node 1 Used to specify the format of data, e.g. "pdf", "ascii", "tab-delimited-dataset". It is similar to the hasFormat property of the pmlp ontology, except that the domain of this property is wdo:Data instead of pmlp:Information. has format Used to specify layout position information of workflow nodes. has coordinate Used to specify layout position information of data labels. has coordinate Used to specify the wdo:Data concepts that a wdo:Method uses as inputs. Inverse of the wdo:isInputTo property. has input Used to specify the wdo:Method concepts where a wdo:Data concept can be used as input. is input to Used to specify the outputs of a wdo:Method concept. has output Used to specify the wdo:Method concepts that generate a given wdo:Data concept. Inverse of the wdo:hasOutput property. is output of Used to set the pmlp:Source of a wdo:Data instance. It is similar to the hasSource property of the pmlp ontology, except that the domain of this property is wdo:Data instead of pmlp:SourceUsage. has source Used to set the pmlp:Source of a wdo:Data instance. It is similar to the hasSource property of the pmlp ontology, except that the domain of this property is wdo:Data instead of pmlp:SourceUsage. has sink Used to link an wdo:SemanticAbstractWorkflow instance to a wdo:Method instance; mechanism to support subworkflows. is abstracted by Used to link a wdo:Method instance to a wdo:SemanticAbstractWorkflow instance; mechanism used to support subworkflows. Inverse of wdo:isAbstractedBy. is detailed by Used to specify abstractions between wdo:Data concepts, e.g., Coordinate is composed of Latitude and Longitude. is composed of Used to specify abstractions between wdo:Data concepts, e.g., Latitude is part of Coordinate, and Longitude is part of Coordinate. Inverse of wdo:isComposedOf. is part of Used to set the pmlp:InferenceEngine of a wdo:Method instance. has inference engine
