Abstract: A schema model allows objects to be contextualized by using stored values that are used to localize the object. The values used for localizing each object that is to be localized are stored in a container class element that is associated with the object that is to be localized. The object having localized term values stored in a container class element is related to another object wherein the objects are related using one of a hierarchical term and an entry term relationship. The associate values allow a user to override by redefinition default values presented by a controlled vocabulary system. The user can further relate term objects by using hierarchical-, entry-, and related-term relationships. This arrangement allows users and systems to more effectively re-use standard data definitions.

Abstract: The present invention provides a method and system for change control management of schema definition objects across disparate systems. A determination is made when a proposed change associated with an object is made; an impact analysis is performed on the proposed change; the change is implemented when the impact analysis indicates that there is no impact on, other system stakeholders otherwise: a change object based on the proposed change is created, voting rights are allocated to users based on the impact analysis; and the proposed change is accepted or canceled in response to the voting. Change control contracts may be associated with the objects. The contracts may be customized to establish change management rules for and enterprise and to specialize rules for certain objects or branches of a Content Class tree corresponding to a department or a discipline. The access to changing the contracts may also be limited to help ensure that the contracts are not bypassed.
