Abstract

The claimed subject matter provides a system and/or method that facilitates utilizing metadata appended to data related to an industrial automation environment with a controller that is associated with a hierarchically structured data model. An interface component can facilitate receipt of data associated with at least one of an instruction set, a configuration, and a collection. An append component can affix metadata to at least one of the instruction set, the configuration, and the collection, wherein the metadata conforms to a hierarchically structured data model.

Claims

1. A system, comprising:

at least one processor;

at least one non-transitory computer readable medium communicatively coupled to the at least one processor, the at least one non-transitory computer readable medium having stored therein computer-executable instructions, comprising;

an interface component configured to receive a data object from an industrial automation device, wherein the data object stores data that relates to at least one of collected data from an industrial automation environment or configuration data for the industrial automation device;

a validation component configured to validate metadata against a template and at least one discoverable service, wherein the metadata is additional data that describes the data stored in the data object in manner that is informative with respect to industrial automation according to a common definition utilized in the industrial automation environment; and

an append component configured to;

in response to the metadata being validated, append metadata to the data object; and

in response to the metadata not being validated, prevent the metadata from being appended to the data object.

2. The system of claim 1, wherein the common definition utilizes a hierarchically structured data model.

3. The system of claim 2, wherein the hierarchically structured data model is organized according to a hierarchy of physical locations of devices in the industrial automation environment.

4. The system of claim 3, wherein the hierarchy of physical locations include at least one of a factory-level, a cell-level, or a subcell level.

5. The system of claim 1, further comprising a security component configured to restrict manipulation of the metadata based on user privileges.

6. The system of claim 1, wherein the metadata employs a naming convention structured according to a physical hierarchy of the industrial automation environment.

7. The metadata system of claim 6, wherein the metadata includes a tag comprising a path within the physical hierarchy associated with a device corresponding to the metadata.

8. The metadata system of claim 1 further comprising a log component configured to track changes to the metadata.

9. The metadata system of claim 1, further comprising a distribute component configured to distribute the data object with metadata to at least one other device.

10. A method, comprising:

employing at least one processor executing computer executable instructions embodied on at least one non-transitory computer readable medium to perform operations comprising;

receiving a data object from an industrial automation device, wherein the data object stores data that relates to at least one of collected data from an industrial automation environment or configuration data for the industrial automation device;

validating metadata against a template and at least one discoverable service, wherein the metadata is additional data that describes the data stored in the data object in a manner that is informative with respect to industrial automation according to a common definition utilized in the industrial automation environment;

in response to the metadata being validated, appending the metadata to the data object; and

in response to the metadata not being validated, preventing the metadata from being appended to the data object.

11. The method of claim 10, wherein the common definition utilizes a hierarchically structured data model.

12. The method of claim 10, wherein the metadata employs a naming convention structured according to a physical hierarchy of the industrial automation environment.

13. The method of claim 12, wherein the metadata includes a logical variable comprising a path within the physical hierarchy associated with a device corresponding to the metadata.

14. The method of claim 10, further comprising logging changes to the metadata.

15. The method of claim 10, further comprising distributing the data object with metadata to at least one other device.

16. A non-transitory computer-readable storage medium having instructions stored thereon that, in response to execution, cause at least one computing device to perform operations comprising:

receiving a data object from an industrial automation device, wherein the data object stores data that relates to at least one of collected data from an industrial automation environment or configuration data for the industrial automation device;

validating metadata against a template and at least one discoverable service, wherein the metadata is additional data that describes the data stored in the data object in a manner that is informative with respect to industrial automation according to a common definition utilized in the industrial automation environment;

in response to the metadata being validated, appending the metadata to the data object; and

in response to the metadata not being validated, preventing the metadata from being appended to the data object.

17. The non-transitory computer-readable storage medium of claim 16, wherein the metadata employs a naming convention structured according to a physical hierarchy of the industrial automation environment.

18. The non-transitory computer-readable storage medium of claim 17, wherein the metadata includes a reference comprising a path within the physical hierarchy associated with a device corresponding to the metadata.

19. The non-transitory computer-readable storage medium of claim 16, wherein the operations further comprising logging changes to the metadata.

20. The non-transitory computer-readable storage medium of claim 16, wherein the operations further comprising distributing the data object with metadata to at least one other device.
