Abstract

A method and apparatus for managing source and derivative data is disclosed. Source data, typically image data, is centralized in a database and derivative data sets are formed from the source data. When it is desired to modify a derivative data, the source data can be accessed and modified to form a new derivative data set instead of modifying the already derived data set. In this way source data integrity is maintained. Derivative data sets are identified and tags are associated with new derivative images. The tag can be embedded in the derivative data or associated with the image as an attached element. The tag identifies information such as the server that generated the derivative image, the source image and any tasks or transformations that were applied to the source image to generate the derivative data. Users of source data can be given access to a central source data repository and access privileges can be assigned. In this way a number of users can access the source files and globally modify all derivative images by changes in the source file.

Claims

1. A data management system, comprising:

a source image data (SID) database containing at least one source image data (SlD) set;

a processing engine adapted perform a first process to apply a sequence of one or more computationally deterministic transformations to the SID set to produce at least one derivative image data (DID) set, to generate an identifier associated with the produced DID set, and to embed the associated identifier within each produced DID set;

a derivative image data (DID) database containing a record of the sequence of transformations for each DID set and all parameters describing each of the transformations;

wherein the embedded identifier comprises means for locating the stored SID set at the DID database and means for retrieving the sequence of transformations and all the parameters describing each of the transformations from the DID database; and

a second process adapted to use the embedded identifier to retrieve the SID set and the transformation sequence stored in the DID database and reinitiate the first process to generate additional DID for the DID set;

wherein the SID set used in the reinitiated process comprises any of the original SID set and at least one alternate version of the original SID set; and

wherein each of the one or more computationally deterministic transformations used in the transformation sequence applied to the SID set in the reinitiated process comprises any of the corresponding original computationally deterministic transformations and at least one alternate version of the corresponding original computationally deterministic transformations.

2. The system of claim 1 wherein the second process comprises an instruction to direct the first process to regenerate the DID set originally produced in the first process and associated with each of the SID sets.

3. The system of claim 1 wherein the second process comprises an instruction to initiate the first process using a modified transformation sequence to produce a new image data set, wherein the second process uses alternate parameters for any element of the transformation sequence originally used in the first process.

4. The system of claim 1 wherein the SID database maintains multiple revisions of each of the SID sets, wherein the specific revision of each of the SID sets used in the first process is recorded in the DID database.

5. The system of claim 4 wherein the second process is adapted to reproduce the DID set exactly from the old revision of one of the SID sets, using the embedded identifier.

6. The system of claim 4 wherein the second process is adapted to produce a new and unique DID set using the same sequence of transformations recorded in the DID database applied to a new current SID set.

7. The system of claim 1 wherein the DID database is adapted to record additional data concerning the SID sets.

8. The system of claim 7 wherein the additional data is the intended usage of the DID sets.

9. The system of claim 7 wherein the additional data is an alternate SID set combined with a corresponding transformation sequence for the first process that can be adapted to be used in place of the DID set associated with the identifier generated by the first process.

10. The system of claim 1 wherein the SID set is adapted to be, inserted into a common image file format and the DID set can be exported to the common image file format.

11. The system of claim 1 further comprising:

at least one networked computer wherein each embedded identifier is adapted to be combined with a name associated with the networked computer to generate a tag associated with each of the DID sets; and

an independent networked computer, connected to a common network, that obtains the DID sets along with the associated tags and can communicate with each of the networked computers and request information concerning the DID sets, and request that a replica DID set be produced and delivered over the network.

12. The system of claim 11 wherein each of the DID sets, exported in common image file formats, contain the tag embedded in the DID set.

13. The system of claim 11 whereby the tag exists within a document which references the associated DID set in the form of a universal resource locator (URL).

14. The system of claim 11 further comprising a process having instructions to:

search through the contents of one or more standard web sites looking for standard image files;

examine each image that it finds looking for embedded tags; and

record information concerning the location of each tagged derivative image in a database.

15. The system of claim 1 adapted to determine the location of each DID set that was derived from a particular SID set, wherein all associated derivative images of the corresponding DID set produced from old revisions of a recently updated SID set are automatically and transparently generated and stored in the DID database.

16. A data management system, comprising:

a process that contains a source image data (SID) set;

a first server associated with the process, the server including a processing engine, wherein the engine is adapted to process the SID set to form a derivative image data (DID) set, to generate an identifier associated with the formed DID set, and to embed the associated identifier within each formed DID set;

a storage medium adapted to receive the DID set;

a second server adapted to distribute the DID set;

a first database having at least one data structure associated with the SID set; and

a second database having at least one data structure associated with the DID set and having data that identifies the second data set as a derivative of the SID set

wherein the identifier embedded within the formed DID set comprises means for locating the at least one data structure associated with the SID set, and means for retrieving the process through which the SID set formed the DID set.

17. A method for managing data, comprising:

providing a source image data (SID) repository having SID sets;

providing access to at least one user to the SID repository;

forming one additional data repository having a subset of the SID sets from the SID repository, wherein the subset of the SID sets is provided from the user;

receiving requests from the user in the additional data repository to form derivative image data (DID) sets from the subset of the SID sets;

selectively processing the requests; and

forming DID sets in response to the requests, comprising the steps of;

applying a sequence of one or more computationally deterministic transformations to each of the requested SID sets to form each DID set;

generating identifiers each uniquely associated with each formed DID set; and

embedding each of the associated identifiers with their corresponding formed DID set;

wherein each of the embedded identifiers comprises means for locating the requested SID set that corresponds to the corresponding formed DID set, and means for locating the sequence of computationally deterministic transformations applied to the requested SID set that corresponds to the corresponding formed DID set.

18. The method of claim 17 wherein selectively processing the requests comprises:

determining whether the user is authorized to access the additional data repository;

allowing the user access to the additional data repository if it is determined that the user has authorization; and

alternatively allowing the user to access the data repository.

19. The method of claim 17 further comprising:

determining whether the SID set in the data repository that corresponds to the subset of the SID set can be accessed by the user.
