The Design Time Catalogue contains the metadata primitives and control loop definition primitives for composition of control loops. As shown in the figure above, the Design Time component provides a system where Control Loops can be designed and defined in metadata. This means that a Control Loop can have any arbitrary structure and the Control Loop developers can use whatever analytic, policy, or control primitives participants they like to implement their Control Loop. At composition time, the user parameterises the Control Loop and stores it in the design time catalogue. This catalogue contains the primitive metadata for any participants that can be used to compose a Control Loop. A Control Loop SDK is used to compose a Control Loop by aggregating the metadata for the participants chosen to be used in a Control Loop and by constructing the references between the participantssparticipants.
Once the Control Loop is composed, it is deployed to Composed Control Loops are commissioned on the run time part of the system, where it is they are stored in the run time catalogue and is are available for instantiation.
