On data model/structure level

Content

• Purpose • Requirements & recomendations• Level of interoperability• Local data models • INSPIRE target data models• Mapping from local to target models• Transformation• Validation and testing

Purpose

• To achieve interoperability of spatial data sets and services

„Focus on spatial and business content“

Analysis of requirements

• INSPIRE Directive (2007/2/EC)• Implementing rules (Commission Regulation (EU) No 1089/2010 as regards interoperability of spatial data sets and services )• Technical Guidelines Annex I, Drafts II,III• Framework Documents• Other Documents

Level of interoperability

• Interoperability components

Level of interoperability Finding the appropriate level of interoperability

Local data models

• Heterogenic data structures (if any...)

• Various spatial representations

• Absence of UML / object oriented notation

• Encoding

• Spatio-Temporal aspects

• Portrayal

INSPIRE target data models

INSPIRE target data models I• Data Specification structure

– Scope– Overview– Data content and structure– Reference systems, units of measurements and grids– Data quality– Data-set level metadata– Delivery– Data capture– Potrayal– Annex A: Abstract test suite– Annex B: Use cases

INSPIRE target data models• UML Data model

Mapping from local to target models

• Protected sites example from SK

Source Data Mapped Application Schema

TransformedValidatedHarmonised Data

Mapping from local to target models

• Land use example from HALE

Transformation

• Land use example from HALE

Testing

• Land use example from HALE
