The Data Grid, like all other collaboration models, has strict rules for contributors to follow and many criteria to abide with. Namespace is one of the rules that govern the contributors.

Topics are confusingly interdisciplinary and sometimes have institutional influence. The intention is to design a hybrid namespace collaboration model for existing organizations to pay lower cost (initial and running) in order to join it. Data resources will be allowed to have colliding names. The contributing organization will be free to set any rules for its internal users to follow (such as taxonomy). However, it will have to take care of a very simple interface to the intended model in order to introduce new contributed resources or to query external ones.
