LINZ has developed a Property Data Management Framework (PDMF) discussion paper that describes how property data can be connected.
We recently sought feedback on the Property Data Management Framework: Developing the model – phase 1 discussion paper. The PDMF is aimed at senior management and technical practitioners responsible for property information in territorial authorities, central government, and the private sector.
The Property Data Management Framework (PDMF) presents a framework describing how property data can be connected.
The framework identifies 5 key aspects of a property: boundary, owner/occupier, structures, services and location. It then takes these aspects and describes how to translate them into recognised digital data. The framework then presents a model that connects the data together.
Please note, this framework is not intended to result in regulatory or legislative changes.
We are now reviewing the feedback we received and will use it to update the discussion document. Once complete, we will release the discussion document as version 1.0 of the PDMF. We are planning to promote version 1.0 of the PDMF to raise awareness and encourage its use, and will use the PDMF as our guiding document as we progress with our Connected Property Data stream of work.
The “Understanding the PDMF” webinars we conducted in March this year is now available on our YouTube channel:
How to read the PDMF discussion paper
If you are a senior manager, Chapters 1-5 of the PDMF will be of greatest interest to you. These chapters describe how we identify a property and may give you an understanding of what the PDMF could mean for your organisation.
If you are a technical practitioner, Chapter 6 onwards will be of greatest interest to you. This shows how property data can be connected to form a package of information about a property as well as supporting information explaining how the model has been developed.
The development of this framework was driven by the need to remove ambiguity and develop a clear understanding about a property across different data owners and users.
The PDMF began as a LINZ-managed project in 2012, following the Canterbury earthquakes of September 2010 and February 2011. The response following the earthquakes identified the need for a framework that would provide well-defined, reliable, and accurate property data relationships.
During the first half of 2017 we conducted a strategic assessment to understand problems that a wide cross-section of stakeholders (not just those in Canterbury) had with property information. This moved the focus nationally.
Since 2017, we have been testing the model using a proof-of-concept system and analysing data as well as sharing information with focus groups. Through this process, we have identified and resolved issues arising from the model.
