Difference between infomodel and IDS-G:MetadataBroker regarding purpose of ConnectorUnavailableMessage #31

Open SebastianOpriel opened 2 years ago

It is stated here https://github.com/International-Data-Spaces-Association/InformationModel/blob/4f9dcb7b7f41421148cbe0a9fccf35336e17364f/taxonomies/Message.ttl#L108 that a ConnectorUnavailableMessage says, that a connector may be available again in the future.

In the Broker docs, it is stated, that a connector won't be ever available again, thus currently all Resources are deleted from the Metadata Broker when a connector sends an unavailable message. See https://github.com/International-Data-Spaces-Association/IDS-G/blob/e470175d77b2b072a8d132cee87c26926e73c797/Components/MetaDataBroker/FunctionsAndCorrelatedMessages/MessagesReceivedByABroker.md?plain=1#L6

I propose to change the line in the MetaDataBroker file to allow the reappearance of a Connector. Or are there any cases where a one-and-forever behaviour makes sense?
