Rights expression system

A method for creating and/or modifying rights expressions in a rights expression language (REL) based on one or more schemas comprising the steps of:

• providing one or more layouts, each layout corresponding to a rights granting paradigm;
• selecting at least one of said one or more of layouts;
• providing one or more type selectors associated with said selected layout;
• selecting at least one of said one or more of type selectors;
• providing one or more REL terms associated with said selected type selector;
• selecting at least one of said one or more of REL terms;
• providing at least one input form associated with said selected REL term;
• inputting a parameter required by said input form;
• and
• generating a rights expression in proper REL semantics defined by said one or more schema based on said selected layout and parameter inputted.

A rights expression system for facilitating creation and/or modification of rights expressions in a rights expression language (REL) based on one or more schemas, said rights expression system comprising:

• one or more selectable layouts, each layout corresponding to a rights granting paradigm, each layout comprising:
• one or more type selection components, each type selection component being adapted to present one or more REL terms;
• and
• one or more input components associated with said one or more REL terms which are invoked based on a selected REL term, said one or more input components allowing input of a parameter required by said selected REL term;
• and
• a data engine that generates rights expressions in proper REL semantics defined by said one or more schemas based on said selected layout and parameter inputted.
