3. Objective
To contribute to the development of the data specifications regarding the 4 themes covered by NatureSDIplus 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>

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

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

7. Reference datasets & data models
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

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

10. UML class diagram X X 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

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

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

13. 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)

14. Data models: Examples

16. From UML to GML Transform the UML model into GML application schema
The standard ISO 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)

17. From UML to GML
