Abstract

A computer implemented method, apparatus and software for automatically transforming data between Electronic Data Interchange (EDI) formats. For generating EDI documents or messages, a source data model with EDI related data is received. Data is transferred from metadata elements of the source data model to variables of a virtual document, based on a mapping that has been previously made. Data assigned to the variables of the virtual document are then transferred to metadata elements of a target data model. An EDI document or message corresponding to the target data model is automatically created as a result, which includes data from the source document or message.

4. The method according to claim 2, wherein the variables of the virtual document are assigned semantic names representative of a type of data to be stored to the variables, and

wherein the maps are created by a user prior to receiving the source data model, based on an intuitive correspondence made by the user from a particular metadata name of one of the metadata of the source data model and a particular semantic name of one of the variables of the virtual document.

5. The method according to claim 1, further comprising:

obtaining, from a database, source-independent data that is used to provide predetermined values for at least one of the metadata of the target data model.

6. A system for automatically generating data in a self-describing markup language format from EDI data, comprising:

a storing unit that stores a plurality of maps for respectively mapping metadata from different types of source documents to variables of a virtual document;

a receiving unit that receives a message or document from a first trading partner as EDI data;

a determining unit that determines a type of the message or document received from the metadata and that determines a type of a target data model;

a virtual document that obtains a first map from the plurality of maps stored in the storing unit based on the type of the message or document as determined by the determining unit, and that maps metadata from the message or document of the first trading partner to variables of the virtual document in accordance with the first map, and that obtains a second map from the plurality of maps stored in the storing unit based on the type of the target data model as determined by the determining unit, and that maps metadata from a message or document of a second trading partner to the variables of the virtual document in accordance with the second map; and

a transmitting unit that transmits values provided to the variables of the virtual document from the message or document from the first trading partner, to the corresponding metadata of the message or document of the second trading partner.

7. The system according to claim 6, wherein self-describing markup language format is XML.

8. The system according to claim 6, wherein the variables of the virtual document are assigned semantic names representative of a type of data to be stored to the variables, and

wherein the maps are created by a user prior to receiving the message or document from the first trading partner, based on an intuitive correspondence made by the user from a particular metadata name of one of the metadata of the message or document received from the first trading partner and a particular semantic name of one of the variables of the virtual document.

9. The system according to claim 6, further comprising:

a database that is communicatively connected to the virtual document, the database storing source-independent data that is used by the virtual document to provide predetermined values for at least one of the metadata of the target data model.

10. A computer readable data storage medium for an EDI system having program code recorded thereon that is executable by a computer to perform the following steps:

storing a plurality of maps for respectively mapping metadata from different types of source documents to variables of a virtual document;

receiving a source data model having a first EDI format corresponding to EDI related data, the source data model including metadata;

determining a type of the source data model from the metadata;

obtaining a first map from the plurality of maps based on the determined type of the source data model, and mapping the metadata of the source data model to corresponding variables of a virtual document in accordance with the first map;

determining a type of a target data model to which data from the source data model is to be transferred to;

obtaining a second map from the plurality of maps based on the determined type of the target data model, and mapping the variables of the virtual document to metadata of a target data model in accordance with the second map,

wherein, when a source message or document is received by the EDI system, the program code is programmed to;

translate the source message or document to obtain its corresponding metadata;

provide the values corresponding to the metadata to the corresponding mapped variables of the virtual document; and

provide the corresponding values of the mapped variables of the virtual document to the corresponding metadata of the target data model.

11. The computer readable data storage medium according to claim 10, wherein the EDI-related data is in a self-describing markup language format.

12. The computer readable data storage medium according to claim 11, wherein the self-describing markup language format is XML.

13. The computer readable data storage medium according to claim 10, wherein the variables of the virtual document are assigned semantic names representative of a type of data to be stored to the variables, and

wherein the maps are created by a user prior to receiving the source data model, based on an intuitive correspondence made by the user from a particular metadata name of one of the metadata of the source data model and a particular semantic name of one of the variables of the virtual document.
