Within the GLUE cooperation we studied an architecture to split a complex GRID into ad-hoc domains.
The criteria to individuate the components of a domain is that internal connectivity is better than the connectivity between neighbor domains.
The intent is to make available an high level view of the GRID whose maintenance and accessibility are inexpensive, compared with the low granularity of classical GIS.
The observations should be published using an existing GIS, although schemas may be slightly different from ordinary ones.
The domains topology is recorded into a MySQL database that can be replicated.
The design of the database has been supported by a UML
schema.
