A method for legacy-based access to non-legacy data includes: receiving, at an intermediation server, a non-legacy data object containing non-legacy content; generating a legacy data object containing the non-legacy content, for storage in a repository; storing, in association with the legacy data object, a non-legacy distribution channel indicator; adjusting a legacy processing mechanism at the repository according to the non-legacy distribution channel indicator; receiving from a client subsystem, via a legacy interface, a request for the non-legacy content; and in response to the request, retrieving and sending the legacy data object containing the non-legacy content, via the legacy interface.
