Patent Document ID: 8751284
Application ID: 12433563

Base Claim:
1. A non-transitory computer-readable medium containing code executable by a computer processor to generate a workflow engine comprising: a Petri net domain model comprising a set of objects comprising a token object, a place object, an arc object, a transition object, and one or more trigger objects, wherein (a) each object represents a particular type of element of a Petri net model and (b) the one or more trigger objects represent triggering a transition object based at least in part on stimuli external to the workflow engine; and one or more runtime components configured for: reading source code representing a particular workflow, wherein the source code indicates elements of the particular workflow and connectors between elements of the particular workflow to sequence the elements of the particular workflow; loading the particular workflow into memory by mapping each element of the particular workflow to one or more objects of the set of objects and by mapping each connector of the particular workflow to one or more objects of the set of objects based on rules governing the Petri net model; and executing the particular workflow loaded into the memory, wherein the workflow engine further comprises one or more abstraction layer components comprising a transition layer from the Petri net domain model to an operating system, the abstraction layer configured to delegate one or more tasks associated with elements of the particular workflow of the Petri net domain to the operating system, via the transition layer, the delegated tasks to be performed by the operating system.

Claim 6:
6. The computer-readable medium of claim 1 wherein prior to loading the particular workflow, the one or more runtime components are further configured to: sequence the elements of the particular workflow using one or more Petri net microkernel components.
