Abstract: A method includes storing, at a discovery service, address information for each of a plurality of information services providers. For each of the plurality of information services, product data of a respective information provider and access right data (defining access rights to the product data) are also stored. At the discovery service, a query is received from an information requester, the query being related to specific product data for a product identifier included in the query. A first information service, of the plurality of information services, is identified as an information provider of the specific product data, and first address information for the first information service is retrieved. The query is routed from the discovery service to the first information service using the first address information. The first information service selectively responds directly to the information requester in accordance with the access right data of the first information service.
