Re: [dataspace-protocol-base-dev] About Catalog Queries

[Jim Marino <jim.marino@xxxxxxxxx>]

Can we please move these types of questions to Github discussions[1] so they are more accessible to people searching?

A catalog replication protocol and participant discovery in a dataspace are two separate issues. Discovery is out of scope, and it is dataspace specific, as there are many different ways to accomplish this.

A catalog replication protocol is not needed because all interactions in DSP are, by design, bipartite - the consumer contacts the provider directly. There are no third-party brokers or intermediaries.

Hello,

At https://eclipse-dataspace-protocol-base.github.io/DataspaceProtocol/2025-1/#replication-protocol 

it is said it is not needed a replication protocol but how one can deal with the use case where a data consumer only knows the characteristics of the Dataset, including the type, schema or coverage of data, but does not know a priori who the data provider is? 

Thank you for your hints

All the best
