LINZ has developed a Property Data Management Framework (PDMF) discussion paper that describes how property data can be connected.
We are seeking 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.
Want to learn more about the PDMF or have questions about how it works or could be implemented?
We’re hosting two Zoom webinars in February and March that are free to attend by registering through Eventbrite.
|Understanding the PDMF: Your top questions answered|
Thursday 11 February at 11.00am
This webinar will focus on general questions received in response to the PDMF since its release in October 2020 and is aimed at people managing property data.
Attendees should read sections 1 to 5 of the PDMF (PDF 4MB) prior to the webinar.
|Understanding the PDMF: For GIS practitioners|
Thursday 4 March at 11.00am
This webinar will focus on the more technical aspects of the PDMF is aimed at technical practitoners.
Attendees should read section 6 onwards of the PDMF (PDF 4MB) prior to the webinar.
We are seeking:
- general agreement on the proposition of what a property is from stakeholders who are mainly senior management in the property information field, and
- technical feedback on the model that describes how the data connects.
Following consultation, we will publish an update to the PDMF.
Consultation is open until Wednesday 31 March 2021.
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 a understanding of what the PDMF could means 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.
This feedback form asks about the technical accuracy and detail inside of the PDMF. Please thoroughly read the PDMF discussion paper and have a copy handy to refer to. The form should take about 15 minutes to complete.
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.
