  1. Implementing CDDA Based on the INSPIRE Protected Sites – Transformation Workflow INSPIRE Conference 2014 – Aalborg María Cabello Pedro Mendive

  2. Summary • Data transformation • GML issues • Validation and testing • Tools • Open issues • Lessons learned

  3. Data Transformation • From Conceptual toPractical • MatchingTable: Mapping thecorrespondence • Transformation: • Format • Data Model • CoordinateReferenceSystem

  4. Data Transformation • Tools requirements • Change Data Model • Read target Data Model: XSD schema. • User utilities • Change CRS • Transform Coordinates • Change format • Write GML (version required by INSPIRE): encoding

  5. GML issues • Encoding of the different elements • Direct relationship • Logical conditions • Value’s Combinations • Enumeration List • Voidable reasons • INSPIRE • ISO

  6. Attribute: geometry (INSPIRE PS) • Type of geometry • gml: Polygon (points excluded) • CRS –encoding urn:ogc:def:crs:EPSG::4258

  7. Attribute: geometry (INSPIRE PS)

  8. Attribute: inspireID(INSPIRE PS) localId: direct link namespace: created by combination

  9. Attribute: legalFoundationDate(INSPIRE PS)

  10. Attribute: legalFoundationDocument(INSPIRE PS) Informationavailable at Data Provider…

  11. Attribute: legalFoundationDocument(INSPIRE PS) Attributetitle Attribute date

  12. Attribute: siteDesignation(INSPIRE PS) AttributedesignationScheme Attributedesignation AttributepercentageUnderDesignation

  13. Attribute: siteDesignation(INSPIRE PS) NationalDesignationCode NationalDesignationCategory IUCN

  14. Attribute: siteName(INSPIRE PS)

  15. Attribute: siteProtectionClassification(INSPIRE PS)

  16. Attribute: ID (GML encoding )

  17. Example 1 all information from CDDA is available

  18. Example 2: Some information from CDDA is not available

  19. Validation and testing • Basic: • Review GML encoding (XML editor) • Visualization: • Right geometry • Right CRS • Advanced • Abstract Test Suite (ATS) • Templatestodocumenttheprocess

  20. Validation and testing • Review of the ATS – Table

  21. Tools Used • Mapping • Matching Table • Transformation • Free and Open Source: Geoconverter and Hale • Validation • Based on ATS of INSPIRE • Extended/specific schemas • Schematron • Oxygen XML editor • XMLSpy XML Editor – Altova • Templates

  22. Open Issues • geometry • legalFoundationDocument • percentageUnderDesignation

  23. Lessonslearned • Thematicexperts are needed • Realisticapproachfrom Conceptual mappingto GML encoding • CloseCollaborationamongdifferentstakeholders: Share information! • Rightencodingismanagedby MIG group
