A rights management module controls access to a data set by processing requests for flexibly defined types of access to the data set and determines if the requested access may be granted. The requester's right for the requested type of access is verified by a verification module that may be part of the rights management core or verified through expansion rights verification modules. Extension verification modules may be contained within the data set itself or obtained from a separate store. Extension verification modules are authenticated by the rights management core.
