This is a link to a resource page in Norwegian, but gives access to a lot of technical information that also should be informative to non-‐Norwegian reading audience.
The Norwegian Mapping Authority has developed a default client using this API, but the API is also exposed to third parties, and several vendors in Norway have developed their own clients for their customers. Most important here, are all the municipalities that are responsible for maintaining the information in the cadastral system.
In the ESDIN project, also a WFS service compliant with INSPIRE Cadastral parcels has been developed (compliant with respect to data content, i.e. validating against the INSPIRE GML schema for CP). The following URL is an example of a request to this service – unfortunately this URL is protected for the time being:

19. Resource description The Norwegian Cadastral system has a multipurpose role and is used for a broad variety of tasks by governmental institutions / the public sector and private companies. Today the most important matters are information for the land market and the planning activities and municipal services.
The Norwegian Cadastre is fully computerized as a central database under the control of the Norwegian Mapping and Cadastre Authority.
There are three main units of the Norwegian cadastral system: Information about Parcels, addresses and buildings. The parcel unit comprises property number, area of surface, land use, owners name / identification and postal address, coordinates for a reference point, the cadastral map and cross-‐reference to buildings and addresses. The address information comprises street name and house number, district codes, reference point and cross-‐reference. The building information comprises building identification number, type / use, number of floors, numbers and data about each flat (including identifier), reference point and cross-‐reference.
20. Spatial data themes Cadastral parcels
Addresses
Buildings
21. Specific Indicators ?
22. Deviation from INSPIRE regulation To be evaluated.

25. Hardware/System Software Ordinary Windows based server park, Oracle database, WebLogic application platform, GeoServer for wms and wfs services.
26. Quality of service Guaranteed between 07-‐18.
27. Topology Not clear what this mean in this case.
28. Service end point To be announced.
29. Lessons learned Fully, working and well used services. Users primarily satisfied.

Annex 1
Structure of the cadastre with respect to content:
The cadastral unit can be mapped to the Inspire harmonized model.
The lower boxes, Building and Address, constitute separate important feature classes, and can be mapped to the Inspire harmonized models-‐
