Model Versions

Every RASON model (named or unnamed) or decision flow that is posted to the RASON Server will have a resource ID of the model instance that was run (including "quick" or synchronous calls). Although for synchronous calls (such as POST rason.net/api/optimize, POST rason.net/api/simulate, etc.) the resource ID will never be referenced by the RASON client; it only appears in the JSON response and the RASON event log (see below). This new resource ID is now included in the "status" returned for each response as "id": resourceId; for example:

  
    "status":{
       "code": 0,
       "id": "11+2019-03-15-00-56-32-664488",
       "codeText": "Solver found a solution.  All constraints and optimality
        conditions are satisfied."
    },
  

Every model/flow that is updated on the RASON Server (via PUT rason.net/api/model/{nameorid}) will have a new ID for the new version; the old ID will identify the old version. GET rason.net/api/model/id can be used to retrieve the text of the current or any past version. Resources are persisted until explicitly deleted by a user and model text is stored under the resource ID. The result is a simple "version control system". Users can reference any model version desired.
