What protocols are supported for a contract negotiation?

[dilipdhankecha2530]

I see all the samples and in the contract negotiation, we need to specify the protocol and in Protocols.java there is only one constant which is ids-multipart.

What does that mean and what other protocols are supported?

Currently, the contract negotiation only supports IDS multipart. This is why there is one constant, that may be extended to include other protocols (specifications coming from e.g. IDS and GAIA-X) in the future. Nevertheless, the actual data transfer supports other protocols, as e.g. http/s. Those implementations are located at extensions.
