DEX: (D004) work_package_definition — Work Package Definition | Date: 2007/09/14 16:11:29 Revision: 1.86 |
The section "Documenting the Definition of activities" states:
The definition of an Activity has been harmonized with the mechanism defined for defining tasks (see DEX 3), to enable a consistent, interoperable approach. This effectively treats the definition as a Document attached to the Activity identified.
I could not find this in DEX 3, and further more I would have thought that the definition of an activity should be done by assigning a document to an activity_method.
The DEX states:
The Approval_assignment links the Work_order to an Approval. The Approval_assignment shall in these circumstances be classified as a "Work_order_approval" (urn:plcs:rdl:std:Work_order_approval) (a sub-class of "Approval_assignment_role" (urn:plcs:rdl:std:Approval_assignment_role)).
I am not sure that there is a requirement to use reference data to make a distinction between what is being approved. It is sufficient to just the Approval_assignment with no classification as specified in the templates.
