Modelling INSPIRE based data specifications for NATURE-SDIplus Co-funded by the Community Programme eContentplus ECP-2007-GEO-317007
2
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 proposed data specs Development candidate data specifications for the 3 Annex 3 themes Theme 17: Theme 18: Theme 19:
3
METHODOLOGY Development of candidate data specifications for the following INSPIRE Annex 3 themes Theme 17: Theme 18: Theme 19: 3
4
Extending As-is analysis with reference datasets and data models User needs Consider European reporting obligations Identify new use cases from a data-oriented perspective Developing data exchange models: Conceptual breakdown Consolidation analysis Fine-tuning and elimination of candidates USED SOURCES 4
5
ATTRIBUTE MATRICES As-is analysisLegal ProvisionUse 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 5
6
Standards (ISO / INSPIRE) Foundation schemas of ISO TC211 Base Types and Models of INSPIRE Generic Conceptual Model (GCM) UML CLASS DIAGRAM 6
7
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 7
8
Creating the 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 UML CLASS DIAGRAM 8
9
DATA MODELS: DISTRIBUTION FORMAT Expert users UML diagram using Enterprise architect (difficult to interpret/hierarchy) 9
10
Expert users UML diagram 10
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) 11

DATA MODELS: EXAMPLES 12

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) 13
