Schema matching example: Administrative Units

Target data model:Administrative Units (.gml)standard: INSPIRE DataSpecification v.3.1projection: SRS 8291

Source data model:Naseleni mesta (.shp)standard: national projection: Macedonia State Coordinate Systems zone 7

Data harmonization process•Matching process (Excel or Dia)– Identification feature types in both the source schema and the

target schema– Identification structural properties of the feature types– Identification attribute names in both schemas– Identification data-value types and characteristics•Creating “pseudo INSPIRE” model (ArcGIS)– adding the necessary attributes and correction of the data type of

existing data •Transformation of “pseudo INSPIRE” data from state projection to SRS 8291 (ArcGIS)•Transformation of model data from national standards to INSPIRE standards with mapping software (HALE)
