A rights expression system and method for facilitating creation and/or
modification of rights expressions in a rights expression language based
on one or more schemas are provided. In one embodiment, the rights
expression system comprises selectable layouts corresponding to a rights
granting paradigm and comprises type selection components. Each type
selection component is adapted to present REL terms and input components.
The input components allow input of parameters required by the selected
REL term. The rights expression system also includes a data engine that
generates rights expressions in proper REL semantics defined by the one
or more schemas based on the selected layout and parameter inputted. The
type selection components and input components may be type selectors and
input forms, respectively, that are implemented in a graphical user
interface.
