Abstract:
1. A method for deriving data provenance information corresponding to a workflow process, the method comprising: deriving, on a computing system, internal provenance information for data pertaining to a first workflow process and storing the derived internal provenance information in a data storage device; deriving, on the computing system, external provenance information for one or more input data objects used by the first workflow process, wherein the one or more input data objects are created by a second workflow process separate from the first workflow process, and storing the external provenance information; using a provenance index service to integrate the internal provenance information and the external provenance information, the provenance index service comprising at least one of: a data model, a domain model, or a provenance service model; in response to a user-submitted query received from a user interface, electronically retrieving data provenance corresponding to the user-submitted query from the integrated internal data provenance information for the workflow process using the provenance index service; and outputting the retrieved data provenance information to a user using the user interface.
