Technique for enabling remote data access and manipulation from a pervasive device
View Patent ↗Methods, systems, and computer program instructions for enabling users of pervasive devices to remotely access and manipulate information in ways that might otherwise be impossible or impractical because of inherent limitations of the device. The disclosed techniques enable a wide variety of data manipulation operations to be performed on behalf of the pervasive device, for a wide variety of content types. In preferred embodiments, no modifications or add-ons are required to the pervasive device.
1. A method of enabling data access and manipulation from a pervasive device, comprising the steps of:
receiving a data access request from a pervasive device;
obtaining the requested data;
determining what data manipulation operations are available for the obtained data; and
providing references to the determined data manipulation operations to the pervasive device.
2. The method of claim 1 , wherein a reference to a determined data manipulation operation comprises a service invocation address.
3. The method of claim 1 , further comprising the steps of:
receiving a request to perform a selected one of the determined data manipulation operations; and
performing the requested operation on behalf of the pervasive device.
4. The method of claim 1 , wherein the determining step further comprises determining what data manipulation operations are available for a content type of the obtained data.
5. The method of claim 1 , wherein the determining step further comprises determining what data manipulation operations are available for a user of the pervasive device.
6. The method of claim 1 , further comprising the steps of:
determining a current location of the pervasive device; and
determining what data manipulation operations are available for the current location of the pervasive device.
7. The method of claim 1 , wherein the determining step further comprises determining what data manipulation operations are available responsive to a type of the pervasive device.
8. The method of claim 1 , further comprising the steps of:
performing one or more data manipulation operations on the obtained data, thereby creating transformed data;
determining what data manipulation operations are available for the transformed data; and
providing references to the determined data manipulation operations for the transformed data to the pervasive device.
9. A computer program product having a computer-readable medium having computer program code encoded thereon to be executed by a processor for enabling data access and manipulating from a pervasive device, the computer program code adapted to perform steps comprising:
receiving a data access request from a pervasive device;
obtaining the requested data;
determining what data manipulation operations are available for the obtained data; and
providing references to the determined data manipulation operations to the pervasive device.
10. The computer program product of claim 9 , wherein a reference to a determined data manipulation operation comprises a service invocation address.
11. The computer program product of claim 9 , further comprising the steps of:
receiving a request to perform a selected one of the determined data manipulation operations; and
performing the requested operation on behalf of the pervasive device.
12. The computer program product of claim 9 , wherein the determining step further comprises determining what data manipulation operations are available for a content type of the obtained data.
13. The computer program product of claim 9 , wherein the determining step further comprises determining what data manipulation operations are available for a user of the pervasive device.
14. The computer program product of claim 9 , further comprising the steps of:
determining a current location of the pervasive device; and
determining what data manipulation operations are available for the current location of the pervasive device.
15. The computer program product of claim 9 , wherein the determining step further comprises determining what data manipulation operations are available responsive to a type of the pervasive device.
16. The computer program product of claim 9 , further comprising the steps of:
performing one or more data manipulation operations on the obtained data, thereby creating transformed data;
determining what data manipulation operations are available for the transformed data; and
providing references to the determined data manipulation operations for the transformed data to the pervasive device.
17. A system for enabling data access and manipulation from a pervasive device, comprising:
a data manipulation server for maintaining a repository of data manipulation operations; and
a protocol proxy in communication with the pervasive device and the data manipulation server and adapted to:
receive a data access request from the pervasive device;
obtain the requested data;
communicate with the data manipulation server to determine, responsive to the obtained data, what data manipulation operations are available; and
provide references to the determined data manipulation operations to the pervasive device.
18. The system of claim 17 , wherein the data manipulation server maintains a service invocation address for a data manipulation operation in the repository and wherein the reference to the determined data manipulation operation comprises the service invocation address.
19. The system of claim 17 , wherein the data manipulation server is adapted to receive a request to perform a selected one of the determined data manipulation operations and invoke the requested operation on behalf of the pervasive device.
20. The system of claim 17 , wherein the protocol proxy is further adapted to determine what data manipulation operations are available for a content type of the obtained data.
21. The system of claim 17 , wherein the protocol proxy is further adapted to determine what data manipulation operations are available for a user of the pervasive device.
22. The system of claim 17 , wherein the protocol proxy is further adapted to:
determine a current location of the pervasive device; and
determine what data manipulation operations are available responsive to the current location of the pervasive device.
23. The system of claim 17 , wherein the protocol proxy is further adapted to determine what data manipulation operations are available responsive to a type of pervasive device.
24. The system of claim 17 , wherein the protocol proxy is further adapted to:
perform one or more data manipulation operations on the obtained data, thereby creating transformed data;
determine what data manipulation operations are available for the transformed data; and
provide references to the determined data manipulation operations for the transformed data to the pervasive device.
