We are working on apiary descriptions for the API methods, that will come soon ...

A description of "plain"" rules can be found at plain rules.

Visual Rules are intended to be used by the Portal exclusively, until a new format is developed which will replace the old format eventually. So, basically, the DCA's documentation is the reference.

Notices/notifications follow the format defined in Orion (Context Broker) for "notify" actions. Context subscriptions

API

All HTTP request must have application/json as MIME type. Responses are application/json also. Generally, the JSON returned as response includes a error field with a string describing an error or null if everything worked fine.

Every request should send a field header for the service (Fiware-Service) and the subservice (Fiware-ServicePath) it refers to.

For service and servicepath only alphanumeric and underscore characters are allowed.

The servicepath is a set of scopes separated by "/" and has the following limitations:

  • each scope must start with "/"
  • 10 maximum scope levels in a path
  • 50 maximum characters in each level, only alphanum and underscore allowed
  • Empty scopes are not allowed, at least it has to have length 1 (excluding the "/")

Fiware-ServicePath is an optional header. It is assumed that requests without Fiware-ServicePath belongs to a root scope "/" implicitely.

Internally to the CEP, scopes do not have a special meaning, so the entire servicepath string is used as a unit, and no operation of CEP takes into account a particular scope inside servicepath. Note this is the current behaviour, although it could change in the future to align more closely to how Orion uses service path (i.e. in a hierarchical way)
