Abstract

A controller is configured to generate and propagate instructions to an execution agent which, in turn, is configured to collect and deposit collected artifacts into a repository. Write access to a location in the repository for collected artifacts that are to be deposited into a specified location is granted to the execution agent. Once the execution agent deposits the collected artifacts in the specified location in the repository, a summary of collected artifacts is propagated to the controller. The controller manages appropriate levels of access to the collected artifacts, while the repository enforces the level of access. The controller can grant read only access to the collected artifacts or it can allow for controlled changes to be made to the metadata associated with the collected artifact. An agent processes the data and generates additional metadata that can be associated with the collected artifacts and then saved in the repository. A system can have more than one repository, where the controller allocates storage in an appropriate repository and issues instructions to the execution agent with the location in an appropriate repository. The summary of the actual collections is then propagated to the controller from the repositories.

Claims

1. A computer implemented method for storing and accessing collected artifacts in an electronic discovery system, comprising:

providing a repository for storing collected artifacts;

providing an execution agent configured to collect artifacts to be stored in the repository; and

providing a controller configured to generate and propagate instructions to the execution agent;

wherein the instructions specify a location in a directory of a staging area for the repository;

wherein the controller is configured to provision the directory of the staging area;

wherein the controller is configured to coordinate allocation and delivery of the collected artifacts to the location in the directory of the staging area;

wherein the controller is configured to manage access control to the collected artifacts in the repository; and

wherein the controller is configured to generate and propagate factual data with regard to delivery of the collected artifacts into the repository.

2. The method of claim 1, further comprising:

providing a processing agent configured to perform data processing on the collected artifacts.

3. The method of claim 2, wherein the processing agent is configured to provide and control read access to the collected artifacts.

4. The method of claim 3, wherein the processing agent is configured to provide and control metadata write access to the collected artifacts.

5. The method of claim 4, wherein the processing agent is configured to update metadata associated with the collected artifacts.

6. The method of claim 1, wherein the controller is configured to export the collected artifacts, along with contextual data, from the repository.

7. The method of claim 1, further comprising providing a plurality of repositories.

8. An electronic discovery apparatus, comprising:

a repository, wherein collected artifacts, along with the contextual data and additional metadata, reside in the repository;

a staging area for the repository;

an execution agent is configured to collect artifacts and to deposit collected artifacts into a location in a directory of the staging area for the repository and to the repository;

a controller configured to generate and propagate collection instructions to the execution agent, wherein the collection instructions indicate a location for depositing collected artifacts in the directory of the staging area, wherein the controller provisions the directory in the staging area, and wherein the controller coordinates allocation of storage in the repository.

9. The apparatus of claim 8, wherein the controller grants write access to the execution agent, and wherein the write access is provided to a location in the repository for collected artifacts that are to be deposited into a specified location.

10. The apparatus of claim 8, wherein a summary of collected artifacts is propagated to the controller once the execution agent deposits collected artifacts in a specified location in the repository.

11. The apparatus of claim 8, wherein the controller is configured to

manage appropriate levels of access to collected artifacts,

wherein the repository enforce a level of access.

12. The apparatus of claim 11, wherein the controller is configured to perform any of granting read only access to collected artifacts and allowing for controlled changes to be made to metadata associated the said collected artifacts.

13. The apparatus of claim 8, further comprising:

an agent configured to process data and generate additional metadata that is associated with collected artifacts and then saved in the repository.

14. The apparatus of claim 13, wherein the controller is configured to grant read only access to an agent that is capable of extracting all data from the repository and exporting the data from the repository.

15. The apparatus of claim 8, further comprising:

a plurality of repositories that are configured to store collected artifacts and metadata,

wherein the controller is configured to allocate storage in an appropriate repository by issuing instructions to the execution agent with a location in an appropriate repository.

16. The apparatus of claim 15, wherein a summary of actual collections is propagated to the controller from the repositories.

17. A non-transitory computer readable medium for storing program instructions that, when executed by a processor, cause the processer to perform operations for storing and accessing collected artifacts in an electronic discovery system, comprising:

providing a repository for storing collected artifacts;

providing an execution agent configured to collect artifacts to be stored in the repository; and

providing a controller configured to generate and propagate instructions to the execution agent;

wherein the instructions specify a location in a directory of a staging area for the repository;

wherein the controller is configured to provision the directory of the staging area;

wherein the controller is configured to coordinate allocation and delivery of the collected artifacts to the location in the directory of the staging area;

wherein the controller is configured to manage access control to the collected artifacts in the repository; and

wherein the controller is configured to generate and propagate factual data with regard to delivery of the collected artifacts into the repository.
