What's in a Name? - Managing Namespaces for Computational Grids

Abstract
Namespace management is one of the most difficult problems to solve
in general for wide area distributed systems in general and for
computtaional grids in particular. Namespaces must of necessity be
scalable and consequently delegated to participants in a computtaional
grid. The naming problem becomes intimately linked to the resource
disovery problem for computtaional grids. Names must be allocated
without recourse to a central authority, but names which are later
found to represent the same object or entity have somehow to be reconciled.
This note presents a tutorial review of the namespace problem and
explores the particular issues for computational grid systems. Some
naming models and issues are presented alongwith some ideas for
constructing reliable and scalable namespace management systems for
wide area computational grids.
