• Form– Physical form of an object as
it exists in the real world– i.e. Building, Pylon, Field,
River, Lake
• Function– ‘Use’ or ‘Purpose’ of an
object in the real world– i.e. Residential, Army
Barracks, Electricity Supply, Agricultural, Reservoir

Permanent Committee on Cadastre, Irish Presidency 20 June 2013
National Spatial Referencing Infrastructure
• Provides Ireland with a consistent authoritative spatial referencing system for the integration and management of national spatial information.
– Common RW objects, unique ID’s referencing, consistent geographic positioning
• Prime2 is a foundation for a modern National Spatial Data Infrastructure.
• Provides users with high quality high intelligence reference data in an easy to use industry standard data format.
• The standards based intelligent data storage model enables the generation of products and services via data schemas designed for user requirements.
• The Prime2 data model enables INSPIRE Directive compliance.
• Provides solution developers and data integrators with a robust framework for integrating 3rd party data.
• Enables OSi to develop enhanced Web Services (Web Feature Services)
– Benefits & Opportunities
Permanent Committee on Cadastre, Irish Presidency 20 June 2013
National Spatial Referencing Infrastructure
• Prime2 Provides Flexibility & Opportunities
– Theme based data management
– ‘Change Only’ data supply
– Enhanced object intelligence
– Extensible data model (surveying of new spatial information)
– Supply schemas
– Integration of high-resolution height model
– Management / integration of 3rd party data
• Merger of OSi, the Property Registration Authority and the Valuation Office
Future Developments
