Discovery Service

The Discovery Service feature in Commerce Events AdaptLink enables complete supply chain visibility by aggregating pointers to applications/data stores that have information about a given product. In many cases, those pointers will be created in response to a tag-read event, but this is not a restriction. Whenever an enterprise creates information about a product, the Discovery Service is notified. The result of a Discovery Service query is a list of all locations that have data about the specified EPC. For scalability reasons, the Discovery Service does not contain actual data, but rather pointers to the local data store where locally defined security policies can be enforced.

Resolution, ONS, and the EPC Repository

To provide effective security on a network and within applications, you must be able to look up authoritative information about any of the canonical names found within the system. This is the role of the EPC Resolution System, which is based on the existing and highly scaled Domain Name System (DNS), and more closely, the EPC Network ONS. DNS currently handles the entire Internet-naming architecture. The EPC Resolution System, like DNS, would not store any data other than pointers to the network services that actually contain the data, thus allowing local security policies to be applied as needed.

The role of this system is as a complementary superdirectory that works with the EPC Repository to provide service-level redirection, thereby allowing...
