Asset Negotiation in EDC is an operation by which a Consumer connector, having obtained a Contract Offer from a Provider connector, negotiates a Contract Agreement with the Provider. Afterwards the Contract Agreement can be executed to have the Provider transfer data to the Consumer.
A negotiation request is initiated on the Consumer side, sent over to the Provider, which sends a Contract Agreement response back to the Consumer (accepted or rejected).
To perform a data transfer, the Consumer must have a Contract Offer from the Provider.
In the Dataspace Catalog pane, click the Negotiate button under an asset.
After negotiation completes, a pop-up appears.
You can then proceed to Initiating a Data Transfer.
