Abstract

An illustrative embodiment of a computer-implemented process for selective delta validation of a shared artifact receives a notification associated with a shared artifact, determines whether a unique key exists for the shared artifact in a symbol data structure, and responsive to a determination that the unique key exists, determines whether an update from an external source occurred. Responsive to a determination that the update occurred from an external source, receives a timestamp associated with the unique key from the symbol data structure to form a received timestamp, determines whether the received timestamp is prior to a last modification time, and responsive to a determination that the received timestamp is prior to the last modification time, performs a delta validation of the shared artifact.

Claims

1. A computer-implemented process for selective delta validation of a shared artifact, the computer-implemented process comprising:

receiving at a data processing subscriber system a notification associated with the shared artifact;

determining whether a set of unique keys exists for the shared artifact in a symbol data structure;

responsive to a determination that the set of unique keys exists in the symbol data structure, determining whether an update from an external data processing source occurred;

responsive to a determination that the update occurred from the external data processing source, retrieving a set of symbol data timestamps associated with the set of unique keys from the symbol data structure;

determining whether a first timestamp in the set of symbol data timestamps is prior to a corresponding last modification timestamp associated with the shared artifact; and

responsive to a determination that the first timestamp in the set of symbol data timestamps is prior to the corresponding last modification timestamp, performing a delta validation of the shared artifact.

2. The computer-implemented process of claim 1, where the step of determining whether a first timestamp in the set of symbol data timestamps is prior to a corresponding last modification timestamp further comprises:

identifying property timestamps associated with properties of interest from the notification; and

comparing each one of the set of symbol data timestamps with a corresponding one of the property timestamps.

3. The computer-implemented process of claim 1, further comprising:

responsive to a determination that the update did not occur from the external data processing source, updating a second timestamp in the set of symbol data timestamps, the second timestamp being associated with an element of the shared artifact.

4. The computer-implemented process of claim 1, further comprising:

responsive to a determination that a first key of the set of unique keys does not exist in the symbol data structure, creating a new entry in the symbol data structure using the first key and a current timestamp.

5. The computer-implemented process of claim 1 where, responsive to a determination that the update from the external data processing source did not occur, the computer-implemented process further comprising:

modifying a property in a tool to form a modified property; and

determining whether the modified property is a secondary location for a property of the shared artifact.

6. The computer-implemented process of claim 5 where, responsive to a determination that the modified property is the secondary location for the property of the shared artifact, the computer-implemented process further comprising:

mapping the modified property to a parent shared artifact;

identifying a unique key of the modified property in the parent shared artifact to form an identified unique key; and

updating a timestamp of an entry in the symbol data structure corresponding to the identified unique key with a current timestamp.

7. The computer-implemented process of claim 1, where the step of determining whether a first timestamp in the set of symbol data timestamps is prior to a corresponding last modification timestamp further comprises receiving a last modification time for a physical file of the shared artifact.

8. A computer program product comprising a computer readable storage medium having computer readable program code embodied therewith, where the computer readable program code when executed on a computer causes the computer to:

receive a notification associated with a shared artifact;

determine whether a set of unique keys exists for the shared artifact in a symbol data structure;

responsive to a determination that the set of unique keys exists for the shared artifact in the symbol data structure, determine whether an update from an external source occurred;

responsive to a determination that the update from the external data processing source occurred, retrieve a set of symbol data timestamps associated with the set of unique keys from the symbol data structure;

determine whether a first timestamp in the set of symbol data timestamps is prior to a corresponding last modification timestamp associated with the shared artifact; and

responsive to a determination that the first timestamp in the set of symbol data timestamps is prior to the corresponding last modification timestamp, perform a delta validation of the shared artifact.

9. The computer program product of claim 8, where the computer readable program code when executed on the computer further causes the computer to:

identify property timestamps associated with properties of interest from the notification; and

compare each one of the set of symbol data timestamps with a corresponding one of the property timestamps.

10. The computer program product of claim 8, where the computer readable program code when executed on the computer further causes the computer to:

responsive to a determination that the update did not occur from the external source, update a second timestamp in the set of symbol data timestamps, the second timestamp being associated with an element of the shared artifact.

11. The computer program product of claim 8, where the computer readable program code when executed on the computer further causes the computer to:

responsive to a determination that a first key of the set of unique keys does not exist in the symbol data structure, create a new entry in the symbol data structure using the first key and a current timestamp.

12. The computer program product of claim 8, where the computer readable program code when executed on the computer further causes the computer to:

modify a property in a tool to form a modified property; and

determine whether the modified property is a secondary location for a property of the shared artifact.

13. The computer program product of claim 12, where the computer readable program code when executed on the computer further causes the computer to:

map the modified property to a parent shared artifact;

identify a unique key of the modified property in the parent shared artifact to form an identified unique key; and

update a timestamp of an entry in the symbol data structure corresponding to the identified unique key with a current timestamp.

14. The computer program product of claim 8, where the computer readable program code when executed on the computer further causes the computer to receive a last modification time for a physical file of the shared artifact.

15. An apparatus, comprising:

a storage device comprising computer executable program code;

a processor coupled to the storage device, where the processor executes the computer executable program code to direct the apparatus to;

receive a notification associated with a shared artifact;

determine whether a set of unique keys exists for the shared artifact in a symbol data structure;

responsive to a determination that the set of unique keys exists for the shared artifact in the symbol data structure, determine whether an update from an external data processing source occurred;

responsive to a determination that the update from the external data processing source occurred, retrieve a set of symbol data timestamps associated with the set of unique keys from the symbol data structure;

determine whether a first;

timestamp in the set of symbol data timestamps is prior to a corresponding last modification timestamp associated with the shared artifact; and

responsive to a determination that the first timestamp in the set of symbol data timestamps is prior to the corresponding last modification timestamp, perform a delta validation of the shared artifact.

16. The apparatus of claim 15, wherein the processor further executes the computer executable program code to direct the apparatus to:
