Abstract:
1. A method of operating a computer device to process a document in a workflow system, the method in the computer device comprising: detecting when a document is at a place in a first workflow network that allows attachment of workflow networks associated with the document to the place of the first workflow network, the first workflow network specifying a plurality of operations to be performed on the document including a first operation and a second operation, the place occurring at a location in the first workflow network after the first operation and before the second operation is performed on the document; determining, when the document is at the place that allows attachment of workflow networks associated with the document, if a second workflow network specified by the document is permitted to be attached to the place of the first workflow network, the second workflow network specifying one or more operations to be performed on the document; and if the second workflow network specified by the document is permitted to be attached to the place of the first workflow network, attaching the second workflow network to the place of the first workflow network such that the document is processed according to the second workflow network before returning, upon completion of processing of the document according to the second workflow, to the place of the first workflow network to continue processing of the document according to the first workflow network before the second operation specified by the first workflow network is performed on the document, wherein the first workflow network comprises a first Petri net and the second workflow comprises a second Petri net.
