.. _representations: ======================= Payload Representations ======================= In PyOpenADR, the complex hierarchies of the OpenADR XML-payloads are represented as Python dictionaries. These have been simplified as much as possible, allowing for a more natural and more readable experience. This means that you don't have to instantiate objects and sub-objects and sub-sub-objects, but that you can define the entire object in a single, declarative statement. This kan keep a simple implementation very compact. The downside is that there is little help from your IDE and there is little discoverability for what contents can be provided in the messages. This page can be used as a reference for that information. To help you, all outgong messages are validated against the XML schema, and you will receive warnings if your messages don't comply to the schema. The following general principles have been applied to representing OpenADR objects in PyOpenADR: - All property names are represented in snake_case instead of CamelCase or mixedCase names. For example: ``requestID`` becomes ``request_id``. - For all properties, the ``oadr*`` and ``Ei*`` prefixes have been stripped away. For example: ``eiResponse`` becomes ``response`` and ``oadrResponse`` becomes ``response``. - OpenADR timestamps are converted to Python ``datetime.datetime`` objects. - OpenADR time intervals are converted to Python ``datetime.timedelta`` objects. - Properties that might have more than 1 copy in the XML representation are put in a list, even if there is just one. This list will be identified by the pluralized version of the originals property name. For example: .. code-block:: xml <...> 1234 5678 <...> Will become: .. code-block:: python3 ... "signals": [1234, 5678], ... - The messages are usually used as a ``message_name, message_payload`` tuple. The message name is kept, for instance, ``oadrCanceledOpt``, and the payload is given as a dict. Below is an alphabetized overview of all messages with their XML and Python representations. .. _oadrCanceledOpt: oadrCanceledOpt =============== OpenADR payload: .. code-block:: xml 200 OK f48e3b7e78 pc1e8ace47 pyOpenADR representation: .. code-block:: python3 {'opt_id': 'pc1e8ace47', 'response': {'request_id': 'f48e3b7e78', 'response_code': 200, 'response_description': 'OK'}} .. _oadrCanceledPartyRegistration: oadrCanceledPartyRegistration ============================= OpenADR payload: .. code-block:: xml 200 OK aba0a805de zf68abb5c2 123ABC pyOpenADR representation: .. code-block:: python3 {'registration_id': 'zf68abb5c2', 'response': {'request_id': 'aba0a805de', 'response_code': 200, 'response_description': 'OK'}, 'ven_id': '123ABC'} .. _oadrCanceledReport: oadrCanceledReport ================== OpenADR payload: .. code-block:: xml 200 OK e4dfe735ea v5d42c35e6 e8bf753e31 pyOpenADR representation: .. code-block:: python3 {'pending_reports': [{'request_id': 'v5d42c35e6'}, {'request_id': 'e8bf753e31'}], 'response': {'request_id': 'e4dfe735ea', 'response_code': 200, 'response_description': 'OK'}} OpenADR payload: .. code-block:: xml 200 OK c36bce5dcb b04cbfb723 ra6231a650 123ABC pyOpenADR representation: .. code-block:: python3 {'pending_reports': [{'request_id': 'b04cbfb723'}, {'request_id': 'ra6231a650'}], 'response': {'request_id': 'c36bce5dcb', 'response_code': 200, 'response_description': 'OK'}, 'ven_id': '123ABC'} .. _oadrCancelOpt: oadrCancelOpt ============= OpenADR payload: .. code-block:: xml u07a26b1cc b1ef7afecc 123ABC pyOpenADR representation: .. code-block:: python3 {'opt_id': 'b1ef7afecc', 'request_id': 'u07a26b1cc', 'ven_id': '123ABC'} .. _oadrCancelPartyRegistration: oadrCancelPartyRegistration =========================== OpenADR payload: .. code-block:: xml z05e4ff0aa pfe04d8439 123ABC pyOpenADR representation: .. code-block:: python3 {'registration_id': 'pfe04d8439', 'request_id': 'z05e4ff0aa', 'ven_id': '123ABC'} .. _oadrCancelReport: oadrCancelReport ================ OpenADR payload: .. code-block:: xml kcb7b5cf7a u1ebe92deb true 123ABC pyOpenADR representation: .. code-block:: python3 {'report_request_id': 'u1ebe92deb', 'report_to_follow': True, 'request_id': 'kcb7b5cf7a', 'ven_id': '123ABC'} .. _oadrCreatedEvent: oadrCreatedEvent ================ OpenADR payload: .. code-block:: xml 200 OK yaa3ee03b1 200 OK ycab9acb9f od864b4ea6 1 optIn 200 OK bf2aad9af8 hc6cf67dab 1 optIn 200 OK jefb88dcbd qdff0da955 1 optIn 123ABC pyOpenADR representation: .. code-block:: python3 {'event_responses': [{'event_id': 'od864b4ea6', 'modification_number': 1, 'opt_type': 'optIn', 'request_id': 'ycab9acb9f', 'response_code': 200, 'response_description': 'OK'}, {'event_id': 'hc6cf67dab', 'modification_number': 1, 'opt_type': 'optIn', 'request_id': 'bf2aad9af8', 'response_code': 200, 'response_description': 'OK'}, {'event_id': 'qdff0da955', 'modification_number': 1, 'opt_type': 'optIn', 'request_id': 'jefb88dcbd', 'response_code': 200, 'response_description': 'OK'}], 'response': {'request_id': 'yaa3ee03b1', 'response_code': 200, 'response_description': 'OK'}, 'ven_id': '123ABC'} OpenADR payload: .. code-block:: xml 200 OK yde9c0369d 200 OK zc9523b16d fefaa2b0f2 1 optIn 200 OK tbeecb7c97 t63a63fea4 1 optOut 123ABC pyOpenADR representation: .. code-block:: python3 {'event_responses': [{'event_id': 'fefaa2b0f2', 'modification_number': 1, 'opt_type': 'optIn', 'request_id': 'zc9523b16d', 'response_code': 200, 'response_description': 'OK'}, {'event_id': 't63a63fea4', 'modification_number': 1, 'opt_type': 'optOut', 'request_id': 'tbeecb7c97', 'response_code': 200, 'response_description': 'OK'}], 'response': {'request_id': 'yde9c0369d', 'response_code': 200, 'response_description': 'OK'}, 'ven_id': '123ABC'} .. _oadrCreatedReport: oadrCreatedReport ================= OpenADR payload: .. code-block:: xml 200 OK ie8ff94fbc p8c56f9ed9 hab1cced95 123ABC pyOpenADR representation: .. code-block:: python3 {'pending_reports': [{'request_id': 'p8c56f9ed9'}, {'request_id': 'hab1cced95'}], 'response': {'request_id': 'ie8ff94fbc', 'response_code': 200, 'response_description': 'OK'}, 'ven_id': '123ABC'} OpenADR payload: .. code-block:: xml 200 OK gde557fcae e1e16137f3 d0f2bcbe89 pyOpenADR representation: .. code-block:: python3 {'pending_reports': [{'request_id': 'e1e16137f3'}, {'request_id': 'd0f2bcbe89'}], 'response': {'request_id': 'gde557fcae', 'response_code': 200, 'response_description': 'OK'}} .. _oadrCreatedPartyRegistration: oadrCreatedPartyRegistration ============================ This message is used by the VTN in two scenarios: 1.

The VTN responds by sending an empty :ref:`oadrResponse`, a :ref:`oadrDistributeEvent` in case there is an Event for the VEN, a :ref:`oadrRequestReregistration` message in case the VTN want the VEN to register again. In case the VEN wants to hear only about new Events, it can send a :ref:`oadrRequestEvent` message to the VTN.
