Abstract

The present invention relates generally to electronic devices with corresponding device DNA and specifically to such electronic devices that share objects by reference to this device DNA. The present invention includes sharing objects among two or more electronic devices with differing object processing capabilities. In particular, a plurality of descriptions of each of the two or more electronic devices and object meta-data, which describes objects, is referenced when objects are exchanged by the two or more electronic devices. For example, if a given electronic device requests an object that it can not process, the object may be transcoded so that this electronic device can process the object. The transcoding is a function of the electronic device'"'"'s description, the object'"'"'s object meta-data, and the intended use of the object.

Claims

providing access to object meta-data, said object meta-data describing the objects, each of said objects maintained on a respective electronic device from the two or more electronic devices; and

triggering a transcoding of an object maintained on a first electronic device from the two or more electronic devices by reference to the object meta-data and by reference to a description of a second electronic device from said two or more electronic devices upon a request to transfer said object to said second electronic device, said second electronic device subsequently able to execute a processing of said object.

2. The method of claim 1, further comprising

linking the plurality of descriptions, wherein a change to a description included in said plurality of descriptions triggers a separate change to each other description included in said plurality of descriptions;

and

synchronizing the separate descriptions to a respective electronic device from the two or more electronic devices, wherein a change to said separate description triggers a corresponding change to said respective electronic device and wherein a change to said respective electronic device triggers a corresponding change to said separate description.

3. The method of claim 1, further comprising

including for each object described in the object meta-data an identification of an electronic device from the two or more electronic devices maintaining, respectively, said each object.

4. The method of claim 1, further comprising copying the object from the first electronic device to the second electronic device upon the request for said object from said second electronic device.
