>  Geographical data in Flanders ▪  Must follow its obligations, regulations, standards, …

>  F.e. SDI-Flanders partnership (decree, implementing decree, commandments, …)

>  MUST’s for describing metadata:

▪  ISO >  19115 (datasets/series), 19119 (services), 19139 (implementation), 19110 (feature catalogue)

▪  INSPIRE >  Directive: Implementing Rules on Metadata + Technical Guidelines on Metadata

▪  SDI-Flanders >  Best Practices on Metadata v1.0 (metadata for datasets, dataset series, services, feature catalogues)

▪  OGC / INSPIRE >  Catalogue Service for the Web (OGC Catalogue Services Specification 2.0.2) = Discovery Service (INSPIRE) =

Zoekdienst (SDI-Flanders)

>  Geoportal: http://www.geopunt.be

The way to open geographical data in Flanders?

Geo > Open 109

>  Open data Portal in Flanders: ▪  SHOULD follow its manual

>  SHOULD HAVE’s for describing metadata: ▪  DCAT-AP

>  Portal: http://opendata.vlaanderen.be/ ▪  CKAN


Geo > Open 110

>  So, do I have to describe my data on both portals? >  The power of metadata: ▪  Describe it only once, ▪  Create multiple use


Geo > Open 111

1


Geo > Open 112

>  Follow the SDI-track to describe metadata (MUST) ▪  Appear on http://www.geopunt.be ▪  AND appear on http://opendata.vlaanderen.be/

>  Because of: ▪  Set keyword “Open data in Flanders” in the metadata record ▪  Via CSW harvest of Geopunt metadata ▪  With filter on keyword “Open data in Flanders” ▪  Mapping to DCAT (XSLT: ISO 19139 to DCAT) ▪  Mapping to CKAN

Geo > Open 113
