Abstract

A method and system for exchanging location content data in different data formats is disclosed. A third-party system makes a request to retrieve, add, modify, or delete location content. The request is made in a first data format. A data exchange system receives the request, converts the request to a second data format supported by a location reference system, and sends the request to the location reference system. The location reference system prepares a response to the request and sends the response to the data exchange system. The data exchange system converts the response to the first data format and sends the response to the third-party system.

Claims

1. (canceled)

2. An apparatus comprising:

input data receiver hardware configured to receive a request including a location code associated with data content in a map data format;

input data transformer hardware configured to validate the map data format of the request and apply a first transformation procedure to the data content of the request; and

output data transformer hardware configured to receive a response based on the request and apply a second transformation procedure to the response.

3. The apparatus of claim 2, further comprising:

a location reference system configured to receive the transformed request from the input data transformer hardware and provide the response to the output data transformer hardware.

4. The apparatus of claim 2, wherein the input data transformer hardware is configured to access the first transformation procedure based on the first map data format.

5. The apparatus of claim 2, further comprising:

output data sender hardware configured to send the transformed response to an external system.

6. The apparatus of claim 2, further comprising:

a plug-in engine configured to receive the first transformation procedure and an error handling procedure from a map vendor.

7. The apparatus of claim 6, further comprising:

error handler hardware configured to apply the error handling procedure to the data content of the request.

8. The apparatus of claim 2, wherein the map data format is geography markup language.

9. The apparatus of claim 2, wherein the input data transformer hardware is configured to sample the data content of the request to determine whether the data content is one of a plurality of supported formats.

10. A method that enables set up and management of data transformation procedures during runtime of a location content management system via a plug-in engine, the method comprising:

receiving a registration message from one or more map vendors, wherein the registration message includes a data transformation procedure for transforming location content;

receiving location content in a map vendor format;

transforming the location content according to the data transformation procedure for a location reference system;

receiving a response from the location reference system; and

transforming the response according to the data transformation procedure.

11. The method of claim 10, wherein the registration message includes error handling procedures.

12. The method of claim 11, wherein the registration message includes a validation rule.

13. The method of claim 12, further comprising:

adjusting the validation rule according to trustworthiness of a source of the registration message.

14. The method of claim 10, further comprising:

receiving a modification message from one or more map vendors; and

modifying the data transformation procedure based on the modification message.

15. The method of claim 10, wherein the map vendor format includes a Geography Markup Language (GML) format, GPS Exchange Format (GPX), Landmarks Exchange Format (LMX), Keyhole Markup Language (KML), whereonearthID, Traffic Message Channel (TMC), or AGORA-C.

16. The method of claim 10, wherein the data transformation procedure includes rules applied to a plurality of data handlers.

17. The method of claim 16, wherein the plurality of data handlers include at least two of a text handler, an image handler, an audio handler, a video handler, or a binary handler.

18. A method comprising:

receiving a request including a location code associated with data content in a map data format;

validating the map data format of the request;

applying a first transformation to the data content of the request;

receiving a response from a location management system based on the request; and

applying a second transformation to the response.

19. The method of claim 18, further comprising:

sending the transformed response to an external device, wherein the request was received from the external device.

20. The method of claim 18 further comprising:

applying an error handling procedure to the data content based on the request.

21. The method of claim 18, wherein validating the map data format of the request comprises:

sampling the data content of the request based on a predetermined rate to determine whether the content data is one of a plurality of supported formats.
