  1. Modelling INSPIRE based data specifications for NATURE-SDIplus Co-funded by the Community Programme eContentplus ECP-2007-GEO-317007

  2. Objective • To contribute to the development of the data specifications regarding the 4 themes covered by NATURE-SDIplus and development of a data model on nature conservation: • Contribute to the testing of the INSPIRE Annex 1 <Protected sites> proposed data specs • Development candidate data specifications for the 3 Annex 3 themes Theme 17: <Bio-geographical regions> Theme 18: <Habitats and Biotopes> Theme 19: <Species distribution>

  3. Methodology • Development of candidate data specifications for the following INSPIREAnnex 3 themes • Theme 17:<Biogeographical regions> • Theme 18:<Habitats and Biotopes> • Theme 19:<Species distribution>

  4. Used Sources Identify new use cases from a data-oriented perspective Extending As-is analysis with reference datasets and data models User needs Consider Europeanreporting obligations • Developing data exchange models: • Conceptual breakdown • Consolidation analysis • Fine-tuning and elimination of candidates

  5. Attribute matrices As-is analysis Legal Provision Use case Reference datasets& data models Attribute matrices • Thematic aggregation of attributes, frequencies and usage scopes • Comparison between content of existing models, as-is and use cases

  6. UML class diagram • Standards (ISO / INSPIRE) • Foundation schemas of ISO TC211 • Base Types and Models of INSPIRE Generic Conceptual Model (GCM)

  7. UML class diagram X • Listing and eliminating ideas • Quick mindmapping schemes • Frequent discussions • INSPIRE philosophy • “Keep it simple” • searching for common denominator • Review by Network partners X X

  8. UML class diagram • Feature catalogue: • a catalogue containing definitions and descriptions of the feature types, feature attributes, and feature associations • Creating the feature catalogue • Feature types (features and geometry) • Attributes • Data types –Enumerations - Codelists

  9. Data models: Distribution format • Expert users • UML diagram using Enterprise architect(difficult to interpret/hierarchy)

  10. Expert users • UML diagram

  11. Data models: Distribution format • Novice users • Dynamic HTML report including definitions and descriptions • Mindmapping schemes • Feature catalogue • Often better insight into hierarchy, associations and application scheme structure (featuretype vs datatype)

  12. Data models: Examples

  13. From UML to GML • Transform the UML model into GML application schema • The standard ISO 19118 prescribes conversion rules for the translation from an application schema in UML into a corresponding XML Schema (W3C, 2002). • OGC: another XML format for GI encoding: GML. • Conversion rules: need to respect UML, ISO and GML constructs • SHAPECHANGE: a Java-based tool that takes a ISO 19109 application schema from a UML model and translates it into a GML application schema (Interactive Instruments)

  14. From UML to GML Transform the UML model into GML application schema
