Geodetic reference systems Indirect Reference Systems Quality Quality evaluation procedures Metadata Positioning Services Portrayal of Geographic Information Encoding formalism Services Spatial operators Strategi for convergence of SOSI in the direction of internationale standards

5 Fundament The strategy is deeply rooted in the report from Statssekretærutvalget for IT, Den norske IT-veien Bit for Bit, especially action point 3.4.6a where it is explicitly emphasized that : “ it should be modelled a strategy for how advantage of participation in international IT-standardization can be increased. This strategy should focus on research, development and larger national reliance in relation with standardization work national and international”.

6 Alternatives SOSI --> ISO SOSI <-- ISO Strategidokumentet ”Contribute to a successive adjustment of the SOSI- standard in the direction of the international standards, in such a way that it by the end of year 200x (with reservation of any delay in the international work), will be available a set of official Norwegian standards based on the ISO 191xx standards.” •ISO-standards (english)? •ISO-standards translated to Norwegian? •ISO-standards as platforms for Norwegian profiles ? •Cooperation NTS/NSF on copyright?

7 The objectives (1)  maintain the positive attitude to standardization work in the Norwegian GI communities.  further development of the SOSI-standard to comprise more feature types, thematic areas, quality elements and metadata- descriptions.  maintain the strong Norwegian contribution within ISO/TC 211, and through this work contribute to that it in short time will be available one family of international standards for geographic information.  contribute to a successive adjustment of the SOSI-standard in the direction of the international standards, in such a way that it by the end of year 2001 (with reservation of any delay in the international work), will be available a set of official Norwegian standards based on the ISO 191xx standards.

8 The objectives (2)  enable skills upgrading regarding use of UML (Unified Modelling Language) as a new conceptual schema language, with the focus on application suppliers, GI producers and users in general.  give sufficient information about standardization work, and the significance of this work on the GI communities in Norway when the standards are available.

10 SOSI part 1 - XML Strategi: ”Med en harmonisert datamodell beskrevet i UML vil SOSI syntaks i overføringsformat kunne leve lenge, samtidig som norsk fagmiljø bygger opp kompetanse på disse språkene”. ”XML will prove to be one of the top ten technologies of the first century of computers” P.G. Barlett i Arbortext
