The Toitū Te Whenua LINZ Property Data Management Framework (PDMF) describes how to connect property data.
The Property Data Management Framework: A model for connecting New Zealand’s property data is now available. The framework describes how property data can be connected. It identifies five key aspects of a property: boundary, owner/occupier, structures, services and location. It explains how to translate them into digital data and connect this data.
We have developed this framework to support senior managers and technical practitioners responsible for property information in territorial authorities, central government, and the private sector.
Please note, no regulatory or legislative changes will result from this framework.
How to read the framework
For senior managers, Chapters 1-5 describe how we identify a property and what the PDMF could mean for your organisation.
For technical practitioners, Chapter 6 onwards show how to connect property data to form a property. We also explain how we developed the model.
Our “Understanding the PDMF” webinar from March 2021 is also available on YouTube:
We developed this framework in response to users’ needs for less ambiguity and clearer information about properties.
LINZ began this work 2012, following the Canterbury earthquakes. The earthquake emergency response highlighted the need for well-defined, reliable, and accurate property data relationships.
In 2017 we conducted a strategic assessment to understand our stakeholders’ needs.
Since 2017, we have tested the model through a proof-of-concept system and analysed data, sharing information with focus groups.
As we learn more, we will continue to develop the PDMF. In the next year we will add material about the Property Spine and Perspectives and incorporate additional feedback that didn’t make it into version 1.0. We will also include more examples explaining how to use the PDMF.
