This paper describes a Swedish approach construction a model of the cadastral domain. The National Land Survey of Sweden (Lantmäteriet) has developed an UML-based, objectorientated information model describing real property information stored in the Swedish Real Property Register. The register is part of the Swedish Land Data Bank System.

The work has been initiated due to a general need for an object-orientated and application independent description of real property information. The project is part of a greater task describing all information handled by Lantmäteriet in an object-orientated way, not focussing on the technical storage of the information, but the information itself. A non-technical modelling approach is the foundation for more cost-efficient development of new software and routines managing and processing cadastral information in the future.

The model is the result of co-operation between governmental agencies, describing the Swedish cadastre. The cadastral domain model has been constructed in a project initiated by Lantmäteriet with the purpose to establish a common description of real property information not limited to local, technical solutions. The work has been done in co-operation with national and local agencies handling cadastral information. The model acts as a basis for an increased data and information interchange between governmental and non-governmental agencies and is a part of the Swedish, digital infrastructure. The model is not a Swedish standard, but might be a contribution to a future Swedish standardisation process.
