After installing, this mediator can be instantiated as follows:

  "@context": [
  "actors": [
      "@type": "SomeActor",
      "someMediator": {
        "@id": "config-sets:sparql-queryoperators.json#mediatorQueryOperation",
        "@type": "MediatorNumberMin",
        "cmn:Mediator/Number/field": "httpRequests",
        "ignoreErrors": true,
        "cc:Mediator/bus": { "@id": "cbqo:Bus/QueryOperation" }

Instead of MediatorNumberMin, MediatorNumberMax could also be used to resolve to the maximum value.

  • cmn:Mediator/Number/field: The field name to mediate over.
  • cmn:Mediator/Number/ignoreErrors: Optional flag to indicate if actors that throw test errors should be ignored, defaults to false.
