Proposed Definitions for the Concept 'Control'
Definition by Satya
There is no explicit mention of control property in the ProvenanceExample, some implicit instances include:
- government (gov) publishes RDF data (f1), where if publication is modeled as a process, then gov (agent) may control (initiate/suspend/terminate) the publication process.
Definition by Jim
see definition of participation. Control is a subtype of participation linking a thing/resource A with a process execution P that implies actions/state changes in A that start or alter P. A control relationship may also imply monitoring of P by A (state changes in A that are caused by the evolution of P).
A control relationship is equivalent to saying that the resource A has an agency role/agency relation with respect to P.
