Abstract

A method and apparatus are provided for preparing a data converter between a source apparatus, in which source data items have been stored according to a predetermined specification of source representation, and a user apparatus having a specification of user representation for the utilization of user data items. The method includes: setting up a pair of machine-interpretable source and user descriptors respectively, of the source and user specifications of representation respectively; and comparing between the source descriptor and the user descriptor to set up therefrom a block for data interpretation by a machine.

Claims

1. A method for preparing a data converter between a source apparatus, in which source data items have been stored according to a predetermined specification of source representation and a user apparatus having a specification of user representation for utilization of user data items, the method comprising:

setting up a pair of machine-interpretable source and user descriptors respectively, of the source and user specifications of representation respectively,

comparing the source descriptor and the user descriptor to determine therefrom a mutual discordance, and

using at least one processor, setting up an interpretation block for data interpretation by a machine, wherein the block is set up to control a conversion between homologous data elements of the source descriptor and the user descriptor respectively.

2. The method according to claim 1, wherein the step of setting up the interpretation block comprises setting up and integrating therein:

a first block arranged for controlling the reading of the source data elements by interpreting information items, on their structure, contained in the source descriptor,

a second block, belonging to said means for controlling a conversion between homologous data elements, by mutually bringing closer semantic and/or syntactic pieces of information contained in said descriptors of the specifications, and

a third block, for controlling writing of the converted data elements by interpretation of information items, relating to their structure, contained in the user descriptor.

3. The method according to claim 1, wherein the method comprises setting up, downstream from the interpretation block, a parameter conversion table.

4. The method according to claim 1, further comprising setting up a structural scheme of the source data for use in preparing the interpretation block.

5. The method according to claim 2, further comprising, in order to bring closer the semantic information items, setting up a semantic graph to represent a link between two thesauruses of respectively the source apparatus and the user apparatus.

6. The method according to claim 5, further comprising setting up, according to the semantic graph, a semantic level conversion algorithm, which is integrated into the interpretation block.

7. The method according to claim 1, further comprising setting up, on the basis of a pair of respective structural schemes of the source apparatus and user apparatus respectively, a syntactic level conversion algorithm, which is integrated into the interpretation block (28).

8. The method of claim 1, further comprising:

setting up a connection between the source apparatus and the user apparatus, and

transferring the data with conversion by said data converter.

9. The method according to claim 8 wherein at least a part of the steps of the data transfer method is performed in at least one of a front logic block of the source apparatus or a front logic block of the user apparatus.

10. The method of claim 8, wherein the step of transferring comprises accessing data of a motor vehicle local area network.

11. The method of claim 8, wherein the step of transferring comprises reading an identification with a reader item, which carries out a recognition of a content of the identification by reading source data stored in said identification through a conversion according to said method.

12. The method of claim 8, wherein transferring comprises receiving with the user apparatus a command transmitted by an apparatus, which is a source of remote control commands and converting the command by the data converter in order to be usable.

13. Equipment for for preparing a data converter between a source apparatus, in which source data items have been stored according to a predetermined specification of source representation and a user apparatus having a specification of user representation for utilization of user data items, the equipment comprising:

a computer-readable storage apparatus, for storing a pair of machine-interpretable descriptors, namely a source and a user descriptor respectively, of the source and user specifications respectively, and

a comparator arranged for achieving a comparison between the source descriptor and the user descriptor and for determining a mutual discordance therefrom;

means for setting up an interpretation block for conversion of data by a machine, wherein the interpretation block is set up to control a conversion between homologous data elements of the source descriptor and the user descriptor respectively.

14. The equipment according to claim 13, comprising correlation means arranged for establishing a semantic graph and/or a said semantic level conversion algorithm, which is integrated into the interpretation block.

15. (canceled)

16. A non-transitory computer readable data storage medium storing a computer program comprising a set of instructions, which can be run on a computer, to implement a method for preparing a data converter between a source apparatus, in which source data items have been stored according to a predetermined specification of source representation and a user apparatus having a specification of user representation for utilization of user data items, the method comprising:

setting up, with the computer, a pair of machine-interpretable source and user descriptors respectively, of the source and user specifications of representation respectively,

comparing, with the computer, the source descriptor and the user descriptor to determine therefrom a mutual discordance, and

setting up an interpretation block for data interpretation by a machine, wherein the interpretation block is set up to control a conversion between homologous data elements of the source descriptor and the user descriptor respectively.

18. The non-transitory computer readable data storage medium of claim 16, wherein the method further comprises:

setting up a connection between the source apparatus and the user apparatus, and transferring the data with conversion by said data converter.
