Tracing of collaborative workflows

A computer-implemented method of tracing a collaborative workflow, the method comprising:

• receiving data that represents an event of the collaborative workflow, the collaborative workflow having a local workflow part and a global workflow part;
• and
• computing, using a processing unit, a new instance state of a model of the collaborative workflow by accessing a command set resource having a mapping of the data representing the event to a list of commands, the new instance state representing an instance of the collaborative workflow obtained through the event of the collaborative workflow and the new instance state complying with rules of a local model of the local workflow part and with rules of a global model of the global workflow part.

A non-transitory computer-readable medium storing instructions, which when executed by a processing unit, provide a method comprising:

• receiving data that represents an event of the collaborative workflow, the collaborative workflow having a local workflow part and a global workflow part;
• and
• computing a new instance state of a model of the collaborative workflow by accessing a command set resource having a mapping of the data representing the event to a list of commands, the new instance state representing an instance of the collaborative workflow obtained through the event of the collaborative workflow and the new instance state complying with rules of a local model of the local workflow part and with rules of a global model of the global workflow part.
