Spatial Data Management and Spatial Data Processing often requires technology of many different computer science disciplines like Data Management, Computational Geometry, Statistics and Data Visualization. Todays approaches to build up GIS Systems for Management and Processing of Spatial Data try to integrate the solutions proposed there into single (large and complex) GIS packages.

We propose a more flexible solution for keeping the specialised software packages independent and autonomous and link them together via a loose communication link. This open network of highly specialized services is called the Cooperative Spatial Information Manager (COSIMA).

We describe a basic cooperation protocol that allows to dynamically link the independent components for any specific complex task. We define the minimum protocol elements all partners have to agree on and give examples for extensions of this basic protocol. As an example we show parts of the protocol elements used in the specific COSIMA configuration currently being developed at ETH Zurich.
