Abstract

Methods and apparatus, including computer program products, implementing and using techniques for providing a discovery service that provides a mapping from an electronic product code to electronic product code information services that include information about an item represented by an electronic product code. The discovery service includes a database containing a list of custodians for the item and a service interface through which electronic product code information services and applications can access the entries in the list. The list includes an entry for each custodian. Each entry includes the electronic product code number, a pointer to an electronic product code information service associated with the custodian, and a trip identifier for the item. The service interface includes several services enabling traceability of the item represented by the electronic product code. Methods and apparatus, including computer program products for using a trip identifier in a discovery service are also described.

Claims

1. A discovery service operable to provide a mapping from an electronic product code to a set of electronic product code information services that include information about an item represented by an electronic product code, the discovery service comprising:

a database containing a list of custodians for the item, the list including one entry for each custodian, each entry including the electronic product code number, a pointer to an electronic product code information service associated with the custodian, and a trip identifier for the item; and

a service interface through which electronic product code information services and applications can access the entries in the list, the service interface including a plurality of services enabling traceability of the item represented by the electronic product code.

2. The discovery service of claim 1, wherein the item is a reusable transport item and the trip identifier uniquely identifies a specific trip through a supply chain for the reusable transport item.

3. The discovery service of claim 2, wherein the trip identifier is generated by the discovery service in response to a user informing the service interface that a new trip is started for the reusable transport item.

4. The discovery service of claim 3, wherein the trip identifier is a number that is generated through a randomization function.

5. The discovery service of claim 2, wherein the service interface is operable to provide data about a specific trip through the supply chain for the reusable transport item in response to a user supplying a trip identifier for the trip to the service interface.

6. The discovery service of claim 2, wherein the reusable transport item is part of a packing hierarchy.

7. The discovery service of claim 1, wherein each entry in the list further includes an alternate identifier representing a combination of the electronic product code and the trip identifier.

8. The discovery service of claim 7, wherein each alternate identifier includes a name and a numerical value.

9. The discovery service of claim 7, wherein the service interface is operable to provide a translation between each alternate identifier and the corresponding electronic product code and trip identifier, thereby enabling query of the discovery service using an alternate identifier.

10. The discovery service of claim 7, wherein each alternate identifier is created by the discovery service in response to a user invoking the service interface.

11. The discovery service of claim 7, wherein the service interface includes a service for returning the most recent custodian of the item to a querying user, based on an alternate identifier.

12. The discovery service of claim 7, wherein the service interface includes a service for returning the entire list of custodians of the item to a querying user, based on an alternate identifier.

13. The discovery service of claim 1, wherein each entry further includes one or more of:

a timestamp indicating when the entry was created, and one or more security flags indicating how the information in the entry may be disclosed in response to a query.

14. A computer-implemented method for using a trip identifier in a discovery service mapping an electronic product code to a set of electronic product code information services that include information about an item represented by an electronic product code, the method comprising:

providing a database in the discovery service, the database being operable to contain a list of custodians for the item, the list including one entry for each custodian, each entry including the electronic product code number, a pointer to an electronic product code information service associated with the custodian and a trip identifier for the item; and

providing a service interface in the discovery service, the service interface being operable to access the entries in the list, the service interface including a plurality of services enabling traceability of the item represented by the electronic product code.

15. The method of claim 14, wherein the item is a reusable transport item and the trip identifier uniquely identifies a specific trip through a supply chain for the reusable transport item.

16. The method of claim 15, further comprising:

receiving user input informing the service interface that a new trip is started for the reusable transport item; and

automatically generating the trip identifier by the discovery service.

17. The method of claim 16, wherein automatically generating the trip identifier comprises generating a number for the trip identifier through a randomization function.

18. The method of claim 14, further comprising:

receiving a user request for data about one or more specific trips for the reusable transport item, the user request including one or more trip identifiers; and

providing data about the one or more trips represented by the one or more trip identifiers to the requesting user.

19. The method of claim 18, further comprising:

applying statistical techniques to the data in order to analyze and optimize the use of the reusable transport item throughout the supply chain.

20. The method of claim 15, wherein the reusable transport item is part of a packing hierarchy.

21. The method of claim 14, further comprising:

receiving a user request to associate one or more alternate identifiers with the electronic product code and the trip identifier; and

associating the one or more alternate identifiers to each entry in the list.

22. The method of claim 21, wherein each alternate identifier includes a name and a numerical value.

23. The method of claim 21, further comprising providing a translation between each alternate identifier and the corresponding electronic product code and trip identifier in response to a query of the discovery service including an alternate identifier.

24. The method of claim 21, further comprising returning the most recent custodian of the item in response to a query from a user, based on an alternate identifier.

25. The method of claim 21, further comprising returning the entire list of custodians of the item in response to a query from a user, based on an alternate identifier.

26. The method of claim 14, wherein each entry further includes one or more of:

a timestamp indicating when the entry was created, and one or more security flags indicating how the information in the entry may be disclosed in response to a query.

27. A computer program product comprising a computer useable medium including a computer readable program, wherein the computer readable program when executed on a computer causes the computer to:

provide a database in the discovery service, the database being operable to contain a list of custodians for the item, the list including one entry for each custodian, each entry including the electronic product code number, a pointer to an electronic product code information service associated with the custodian and a trip identifier for the item; and
