Approach: Model ToU consists of separate statements referring to elementary combinations of –an operation (What kind of usage is undertaken?) –an intention (What is the purpose of the usage?) Building up a matrix of generic operations / intentions –Ambition: chosen categories should be applicable for data, services and applications!

Model: matrix operations intentions Type A - private individual no commercial interest purpose: personal information and use in personal environment Type B - company direct or indirect commercial interest purpose: making profit Type C - public authority no commercial interest purpose: administration based on legal regulations Type D - public utility institution no commercial interest purpose: depends on kind of institution Type E - educational institutions no commercial interest purpose: teaching and related research
Model: matrix operations intentions Cells contain descrete values: OK usage is permitted without restrictions ! usage is permitted with restrictions X usage is prohibited ? usage requires compliance with process regulations usage is not defined

more on operations operations –exakt meaning depends on type of SDI resource (data, services, applications) –documentation of template must comprise adequate definitions in process
more on intentions Intentions –different types are highly correlated with specific segments of SDI users, but not synonymous! –e.g. public authorities or educational institutions can act as a company as well knowledge of user segment is not sufficient for the awareness of the intention –therefore neutral terms were chosen for the categorization of intentions
optional: request for additional exemplars (JP) Harmonization of ToU: using the template assign exemplars to SDI resources (Joint Project 05) create template (Task Force) feedback (Working Group) hardening the template (TF) definition of ToU exemplars (TF) work out doumentation / instruction sheet (TF) current step forward template and exemplars to members of Joint Project 2005 (TF) dec ! one for each reappearing set of legal / economical determining factors establish GDI NRW standard for ToU 2006
Conclusion Beside the technical requirements of standardization exists the need for the standardization of economical rules for SDIs. Economical rules are the definite and legal formalized descriptions of the usage of services, data and applications of SDIs. Harmonization process has started in NRW. First results are encouraging but there is still a long way to go.
