Abstract

The present disclosure is concerned with generating a unique representation of a physical asset from a plurality of datasets representing information relating to the physical asset. Each dataset is generated by a system that acquires the dataset in a system-specific format. Each dataset that includes information about the attributes of a physical asset is mapped to a corresponding system-specific global dataset, based on a global data model. The global system-specific datasets generated are merged together to generate a global dataset, based on the global data model. The global dataset therefore uniquely represents the physical asset.

Claims

1. A method of generating a unique representation of a physical asset from a plurality of system-specific datasets associated with a plurality of systems, each system-specific dataset representing, in a system-specific data format, the physical asset and comprising system-specific information about the physical asset, the method comprising:

mapping each of the system-specific datasets into a global system-specific dataset based on a global data model; and

merging each of the global system-specific datasets into one global dataset based on the global data model, the global dataset uniquely representing the physical asset and comprising information about the physical asset from the plurality of systems, wherein the merging is based on a set of rules.

2. The method according to claim 1, wherein the step of merging based on a set of rules comprises selecting global data from amongst conflicting data of two or more global system-specific datasets.

3. The method according to claim 2, wherein the step of selecting global data comprises using a logic function.

4. The method according to claim 2, wherein the step of selecting global data comprises providing the conflicting data of the two or more global system-specific datasets to a running service.

5. An arrangement for generating a unique representation of a physical asset from a plurality of system-specific datasets associated with a plurality of systems, each system-specific dataset representing, in a system-specific data format, the physical asset and comprising system-specific information about the physical asset, the arrangement comprising:

means for mapping each of the system-specific datasets into a global system-specific dataset based on a global data model; and

means for merging each of the global system-specific datasets into one global dataset based on the global data model, the global dataset uniquely representing the physical asset and comprising information about the physical asset from the plurality of systems, wherein the merging is based on a set of rules.

6. The arrangement according to claim 5, wherein the physical asset is a device of a power utility.

7. The arrangement according to claim 5, wherein at least the global data model is a text mark up language format.

8. The arrangement according to claim 5, wherein the means for merging based on a set of rules comprises a logic function for selecting global data from amongst conflicting data of two or more global system-specific datasets.

9. The arrangement according to claim 5, wherein the means for merging based on a set of rules comprises a running service to which the conflicting data of the two or more global system-specific datasets are provided.

10. A computer program for generating a unique representation of a physical asset from a plurality of system-specific datasets associated with a plurality of systems, each system-specific dataset representing, in a system-specific data format the physical asset and comprising system-specific information about the physical asset, the computer program comprising:

program instruction means for means for mapping each of the system-specific datasets into a global system-specific dataset based on a global data model; and

program instruction means for means for merging each of the global system-specific datasets into one global dataset based on the global data model, the global dataset uniquely representing the physical asset and comprising information about the physical asset from the plurality of systems, wherein the merging is based on a set of rules.

11. A computer program for execution by a computer to generate a unique representation of a physical asset from a plurality of system-specific datasets associated with a plurality of systems, each system-specific dataset representing, in a system-specific data format the physical asset and comprising system-specific information about the physical asset, the computer program comprising the following procedures:

mapping each of the system-specific datasets into a global system-specific dataset based on a global data model; and

merging each of the global system-specific datasets into one global dataset based on the global data model, the global dataset uniquely representing the physical asset and comprising information about the physical asset from the plurality of systems, wherein the merging is based on a set of rules.
