Marketplaces

Data sharing always takes place peer-to-peer in a data space with data discovery being provided via catalogs. This basic functionality does not cover any form of business model. Since many dataspaces require not only searching for available data but also platforms for trading, buying, and selling data, it is expected that many different models of data marketplaces will emerge within data spaces.

Again, these can be centralized marketplaces, federated marketplaces, or individual decentralized business platforms. Similar to how resources can be bought and sold on exchanges, functions can be created for data contracts. A marketplace can also provide a catalog that enables data discovery as well as a business platform to buy and sell data. Or it simply may act as a broker facilitating the negotiation of data contracts for a fee.
