Whitepaper: Emphasize the benefits of a dataspace vs. other approaches

[AScFH]

“You know what? Let’s build a joint venture together.” Francesca proposes. “A non-profit that facilitates data exchange between food retail stores and chains and their suppliers, where everyone involved can exchange data in a controlled manner.

Here we can mention the alternative approaches and their pros and, especially, cons, which could be:

• a central data lake
• organizing the data exchange without a dataspace system by exchanging data directly basing on (paper) contracts
• ...

There we can add benefits of data space systems in general

• decentralized data storage, on-demand data integration
• policy management and policy enforcement
• ...
• evtl. also additional options such as demand-driven application of data pre-processing services (e.g. anonymization)

• the whole document is about "why we need data spaces"
• "dramatic arch" in storytelling; e.g. negative public examples whith data lakes
