Either way is fine, advantage of inheritance from Organization would be lost e.g., industry standard attribute configuration which Reltio's Organization entity provide (can be done in new entity but eventually a modular approach to re-use the existing configuration would be lost). If party/organization is not used as the base entity then relationships like hasAddress would not be supported for new entity.
