Abstract

Methods and apparatus, including computer program products, for real-time and context-aware tracking of items. Tags bound to items are read and information read from the tags and location information about the tags is provided by at least two enterprises and used to maintain disposition information about the items, which is made visible to enterprises in the supply chain. The disposition information can be mapped to a world model that tracks the items and circumstances affecting the items, for example, geo-spatial events and traffic delays. Visibility of the disposition information can be controlled through authorization. Visible information can include relationships between particular items and business documents such as order and shipping documents.

Claims

1. A method of receiving identification information identifying a physical object, the method comprising:

receiving at a generic user interface component, identification information from an identification capture system that obtains the identification information from a tracking component associated with a physical object, the identification information identifying the physical object to which the tracking component has been associated, wherein the identification information is encoded in a first format compatible with an input device for the identification capture system and wherein the generic user interface component lacks functionality to format input for subsequent insertion in one or more data fields of a virtual representation of the physical object; and

transmitting the received identification information to a universal decoding module that includes logic for reformatting identification information from a plurality of different types of identification capture systems, wherein the universal decoding module is configured to;

determine the virtual representation of the physical object, the virtual representation being predefined by a process flow to receive the identification information, wherein the virtual representation has at least one data field to store the identification information;

identify a second format used for the at least one data field and;

convert the first format compatible with the input device for the identification capture system into the second format of the at least one data field.

2. The method of claim 1, wherein the input device of the identification capture system comprises a barcode scanner.

3. The method of claim 2, wherein the tracking component comprises a bar code.

4. The method of claim 1, where in the input device of the identification capture system comprises a radio frequency identification (RFID) reader.

5. The method of claim 4, wherein the tracking component comprises an RFID tag.

6. The method of claim 5, wherein the RFID tag is a smart label.

7. The method of claim 1, wherein the identification capture system comprises a voice recognition system and the tracking component comprises a human readable label that a worker can read into the voice recognition system.

8. The method of claim 1, further comprising linking portions of the identification information to the corresponding data fields of the virtual representation when the virtual representation includes more than one data field.

9. The method of claim 1, wherein the conversion identifies a data format with the input device of the identification capture system using header information included in the received identification information.

10. The method of claim 9, wherein the conversion further comprises using the identified data format and an index table comprising format conversions to determine how to convert the first format compatible with the input device into the second format of the at least one data field.

11. The method of claim 1, wherein the conversion is performed by one of multiple tag readers each configured to perform different conversions.

12. The method of claim 11, wherein the conversion further comprises using header information included in the identification information compatible with the input device to identify a tag reader configured to read the identification information.

13. The method of claim 1, wherein the physical object identified by the identification information is a location, stock, or storage receptacles used to contain or move the stock.

14. The method of claim 1, further comprising storing previously received identification information that identifies events and the previously received corresponding identification information that identifies a virtual circumstance for the event.

15. The method of claim 14, further comprising verifying whether the event corresponds with the virtual circumstances by comparing the identification information received from the identification capture system with the previously stored identification information corresponding with the virtual circumstances, wherein the physical object specified by the identification information received from the identification capture system comprises the virtual circumstance, the event, or both.

16. The method of claim 1, wherein the generic user interface component comprises a tagging component.

17. The method of claim 1, wherein the universal decoding module comprises an object interface component.

18. A computer-implemented method for transmitting identification information identifying a physical object, the method comprising:

determining a data field specified by a process flow, the data field having one or more fields to store an identification information to be encoded in a tracking component using an object interface component, the identification information to identify a physical object that is associated with the tracking component;

receiving, at a generic user interface component that lacks functionality to format input for subsequent insertion in data fields of a virtual representation of the physical object, the identification information in a first format compatible with one or more data field fields, and identifying a second format used by the object interface component to encode the identification information in the tracking component; and

converting the first format compatible with the one or more data field fields into the second format used by a universal decoding module, and forwarding the encoded identification information to the universal decoding module for encoding in the tracking component.

19. The method of claim 18, wherein the identification information is encoded into a bar code format or an RFID format.

20. A system for receiving and transmitting identification information identifying a physical object, the system comprising:

an identification capture system to receive identification information encoded in a tracking component associated with a physical object and to transmit the identification information to the tracking component, the identification information identifying the physical object to which the tracking component is associated;

a universal decoding module to receive the identification information from a data field from multiple data fields, the data field having one or more fields to store the identification information in a first format compatible with the data field fields, and to encode the first format into a predetermined second format used by the identification capture system; and

a context-aware intelligence component to determine the data field from the multiple data fields to receive the identification information encoded in the second format from the identification capture system, and to decode the second format into the first format used by the one or more fields of the determined data field.
