Message Types

IDS messages and their content are defined here. The table below lists the supported message types. Thereby, it is to be distinguished whether the Dataspace Connector provides functionality for sending messages as request or response, or for processing incoming messages.

IDS Message Type Outgoing Incoming Description
ArtifactRequestMessage request x message asking for retrieving a specified artifact
DescriptionRequestMessage request x message requesting metadata (If no URI is supplied via the ids:requestedElement field, this messages is treated like a self-description request.)
ContractRequestMessage request x message containing a contract offer
ArtifactResponseMessage response x message that contains the artifact’s data in the payload
DescriptionResponseMessage response x message containing the metadata of a requested object
ContractAgreementMessage request + response x message containing a contract agreement
ContractRejectionMessage response x message indicating rejection of a contract
RejectionMessage response x message that notifies the issuer that processing the request message has failed
NotificationMessage request x message is informative and no response is expected
LogMessage request x message that is used to transfer logs e.g. to the clearing house
MessageProcessedNotificationMessage response x message that notifies whether a message has been received and successfully processed
ConnectorUpdateMessage request   message notifying the recipient(s) about the availability and current configuration of a connector
ConnectorUnavailableMessage request   message indicating that a specific connector is unavailable
ResourceUpdateMessage request x message indicating the availability and current description of a specific resource
ResourceUnavailableMessage request   message indicating that a specific resource is unavailable
QueryMessage request   message intended to be consumed by specific components

request = initially send this kind of IDS message, response = response with this IDS message

IDS-Multipart Messages

The most common way to exchange IDS-Messages in an IDS data ecosystem between the participants are multipart messages. IDS multipart messages consist of two parts, a header and a payload. The header part contains the actual IDS-Message, such as a ConnectorUpdateMessage, LogMessage or a DescriptionRequestMessage. A payload may be required for some IDS multipart message types, but it does not always have to be. IDS-Messages exist which do not require a payload for additional information, such as a ConnectorUnavailableMessage to an IDS Metadata Broker. The IDS Metadata Broker already knows which connector changes its status by the ids:affectedConnector in the message header and thus the actual ConnectorUnavailableMessage. If a QueryMessage is sent as a counterexample, the query itself must be present in the payload of the multipart message, which makes the payload mandatory for this specific message-type. Following is a listing of all IDS-Messages as sent by the Dataspace Connector, with an example of each. Fields in the actual IDS-Messages in the header, which are mandatory, are additionally listed separately.

More information about Multipart in the IDS context, can be found here.
