Abstract

Provided are techniques for managing constraints. Content data and content metadata that is associated with the content data is stored. In response to receiving a change to one of the content data and the content metadata, a provenance value is calculated based on the change, wherein the provenance value represents a change in content between the changed content data or the content metadata and an original version of the content data or the content metadata, and a lineage value is calculated based on the change, wherein the lineage value represents a change in authorship between the changed content data or the content metadata and the original version of the content data or the content metadata. It is determined whether the calculated provenance value violates at least one constraint. It is determined whether the calculated lineage value violates at least one constraint. In response to determining that the calculated provenance value or the calculated lineage value violates at least one constraint, one or more actions associated with the violated constraint are performed, wherein the one or more actions include allowing the change and preventing the change.

Claims

1. A method in a content management system for enforcing constraints, comprising:

in response to receiving a change to at least one of content data and content metadata associated with the content data;

calculating, via a processor of a computer, a provenance value based on the change;

calculating, via the processor of the computer, a lineage value based on authorship of the change, wherein the calculated lineage value represents a number of different authors associated with the change; and

in response to determining that at least one of the calculated provenance value and the calculated lineage value violates at least one constraint, performing, via the processor of the computer, one or more actions associated with the at least one violated constraint, wherein the one or more actions include one of allowing the change and preventing the change, wherein;

the at least one constraint is violated based on a predetermined threshold value.

2. The method of claim 1, further comprising:

in response to determining that the calculated provenance value and the calculated lineage value do not violate the at least one constraint, allowing the change to the at least one of the content data and the content metadata.

3. The method of claim 1, further comprising:

determining whether the at least one constraint is enabled.

4. The method of claim 1, further comprising:

displaying at least one of the calculated provenance value and the calculated lineage value.

5. The method of claim 1, wherein the one or more actions include at least one custom user-defined action.

6. The method of claim 1, further comprising:

storing the calculated provenance value and the calculated lineage value.

7. A content management system for enforcing constraints, comprising:

a processor; and

a storage device connected to the processor,

wherein the storage device has stored thereon a program, and

wherein the processor is configured to execute instructions of the program to perform operations, wherein the operations comprise;

in response to receiving a change to at least one of content data and content metadata associated with the content data;

calculating a provenance value based on the change;

calculating a lineage value based on authorship of the change, wherein the calculated lineage value represents a number of different authors associated with the change; and

in response to determining that at least one of the calculated provenance value and the calculated lineage value violates at least one constraint, performing one or more actions associated with the at least one violated constraint, wherein the one or more actions include one of allowing the change and preventing the change, wherein;

the at least one constraint is violated based on a predetermined threshold value.

8. The content management system of claim 7, wherein the operations further comprise:

in response to determining that the calculated provenance value and the calculated lineage value do not violate the at least one constraint, allowing the change to the at least one of the content data and the content metadata.

9. The content management system of claim 7, wherein the operations further comprise:

determining whether the at least one constraint is enabled.

10. The content management system of claim 7, wherein the operations further comprise:

displaying at least one of the calculated provenance value and the calculated lineage value.

11. The content management system of claim 7, wherein the one or more actions include at least one custom user-defined action.

12. The content management system of claim 7, wherein the operations further comprise:

storing the calculated provenance value and the calculated lineage value.

13. A computer program product for enforcing constraints, the computer program product comprising:

a computer readable storage device having computer readable program code embodied therewith, the computer readable program code, when executed by a processor of a computer, being configured to;

in response to receiving a change to at least one of content data and content metadata associated with the content data;

calculate a provenance value based on the change;

calculate a lineage value based on authorship of the change, wherein the calculated lineage value represents a number of different authors associated with the change; and

in response to determining that at least one of the calculated provenance value and the calculated lineage value violates at least one constraint, perform one or more actions associated with the at least one violated constraint, wherein the one or more actions include one of allowing the change and preventing the change, wherein;

the at least one constraint is violated based on a predetermined threshold value.

14. The computer program product of claim 13, wherein the computer readable program code, when executed by the processor of the computer, is configured to:

in response to determining that the calculated provenance value and the calculated lineage value do not violate the at least one constraint, allow the change to the at least one of the content data and the content metadata.

15. The computer program product of claim 13, wherein the computer readable program code, when executed by the processor of the computer, is configured to:

determine whether the at least one constraint is enabled.

16. The computer program product of claim 13, wherein the computer readable program code, when executed by the processor of the computer, is configured to:

display at least one of the calculated provenance value and the calculated lineage value.

17. The computer program product of claim 13, wherein the one or more actions include at least one custom user-defined action.
