Object Naming Service

Finding information about a tagged object is a challenge because the information could be located in any one of a number of analytic systems. To solve this problem, EPCglobal created the Object Naming Service (ONS), which is a global distributed database of EPC tag identifiers. Users query the ONS with a particular EPC, and the ONS returns the address information that contains information associated with that EPC. The user then queries the database directly to obtain the desired data. The ONS is a resolution mechanism that directs an EPC query to where information associated with that EPC can be found on the network.
