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.
