Metadata Content Guidance.docx
Hi Matt
Thanks for sending the licence so quickly, and I’ll follow up with NZ Open Government Data team
next.
Thanks also for being open to updating the metadata. Attached is the draft metadata content
guidance prepared by Rob Deakin (cced). This reference document may help give your
committee members some assurance about why we are asking for the metadata to be updated.
ACT
I double checked the
geographic extent, and note that the example provided in the guidelines is
for NZ Property Titles which does included the Chathams, but what I had not realised is that it
doesn’t cover all of Fiordland as there is no property title for this area.
Here’s a revised geographic extent, which covers mainland New Zealand, Stewart Island and the
Chathams.
166.426401, -176.128804, -47.289604, -34.129705

Hi Matt
Just checking in with you about receiving a copy of your existing licence for the suburbs data.
Also I meant to mention this yesterday, as I noted we have the potential to achieve a quick win if
we were to add a geographic extent and purpose to your metadata for suburbs.
The
geographic extent is the four coordinates of a bounding box
An example of geographic extent for a LINZ national dataset which you could reuse is :
166.688755883, -175.833301833,

-47.2899925167, -34.12963565
For
purpose we could reuse the text agreed for the OIA response
“Fire and Emergency New Zealand maintains the New Zealand Localities Dataset (NZ
Localities) principally for its own operational purposes, to mitigate the risk that emergency
responses are despatched to inaccurate locations (and the consequent delay in that response
arriving at the location that it is required).
UNDER
The development and maintenance of NZ Localities is consistent with Fire and Emergency
New Zealand’s principal objectives and main functions. These are set out in sections 10
and 11 of the Fire and Emergency New Zealand Act 2017, and include the following

Introduction
Metadata is “data that describes data”. It is most commonly used to help
make data discoverable, usable and understandable. It can also be used
as a tool to help manage datasets throughout their lifecycle: from design,
through ongoing management and maintenance, to retirement and
archiving.
This document provides guidance on to dataset managers for put in place the minimum
amount of metadata to enable potential users to:
• discover key datasets,
ACT
• assess their fitness-for-purpose, and
• have confidence that the data is being used or analyzed appropriately.
It is aimed specifically at lead agencies that have data improvement plans in place for
key resilience and climate change datasets identified by LINZ, as part of LINZ’s Resilience
and Climate Change work programme.
It provides guidance specifically on what items of metadata (metadata elements) should
UNDER
be recorded as a minimum requirement to allow potential users to assess the fitness-for-
purpose for their particular uses. Achievement of this minimum requirement is used as
assessment measure and target in creating the improvement plan.
For fuller introductions to, and explanations of, metadata and its use there are already
numerous resources available on-line that provide this. Some of these are listed in the
final section of this document, and we recommend reviewing these, particularly those
that relate to the ISO 19115 suite of metadata standards for geographic information.
INFORMATION
What is metadata?
Within the context of data and information management, metadata is often used to
RELEASED
document and describe resources that contain or provide access to data, such as dataset
or web-services.
Different domains, such as medicine, education, publishing and statistics have developed
specific formats for the ways in which they describe data and information resources.
Perhaps the most widely known systems are library catalogue systems, where each
OFFICIAL
resource is tagged with information that tells the would-be user about its:
• title
• subject
THE
• author
• publisher
• publication date
• edition number
Metadata Contents Guidance – for key resilience and climate

change datasets
Land Information New Zealand © Crown Copyright
• ISBN number (unique ID)
• where it can be found
All of this information is provided as a summary, a metadata record, to anyone who may
be interested in tracking down a particular publication, or books on a particular topic, or
works by a specific author published between set dates.
For geographic datasets, we have an interest in knowing similar things. If we wanted to
discover whether there was building outline dataset available for Christchurch, it would
be useful if we could search a single data catalogue to find it.
Approaches could be to search by:
• title
ACT
• subject
• the source organisation
• the spatial extent (area of interest)
If were identified one or more datasets of interest, we would want to find out whether
they were fit-for-purpose for our particular use. To do this we may want to know:
• Why the data was originally captured?
UNDER
• What organisation created the data?
• How was the data captured?
• When was it captured?
• When was it published?
INFORMATION
• How often is updated?
• Is it a complete record covering the whole of Christchurch?
RELEASED
• How accurate is the data?
• Does the dataset include particular fields we are interested in? (e.g. building use,
value, age, construction type, ownership.)
• Are their licensing restrictions on how the data can be used?
OFFICIAL
• Is there a cost to using the data?
• What formats is it available in?
If we want to analyse the data with confidence, can we determine:
THE
• What units of measure are used for key attributes? (e.g. is “value” given as NZ$,
or NZ$ ‘000?; is area in m2, ft2 or ha?)
• If an ID field is present, is it unique for each record, and is it persistent?
• If code lists are used to describe building material, what do the codes mean?
Metadata Contents Guidance – for key resilience and climate

change datasets
Land Information New Zealand © Crown Copyright
• If a value is given to five decimal points, is that degree of precision reliable?
As you can see, different levels of metadata detail are required to support:
• Discovery (requiring relatively high-level metadata only)
• Assessing fitness-for-purpose (detail relating to content, accuracy and quality is
needed)
• Appropriate use (unambiguous definition of the data and what it represents is
needed)
Metadata standards for geographic information
The use of common ways to record metadata, using a standard structure with common
ACT
fields used to record metadata “elements”, is something that is seen in different
disciplines and domains.
Geographic information is distinct from other forms of information; it inherently has some
unique characteristics e.g. its spatial extent, the geographic / map projection system
used to define location, positional accuracy and precision of coordinates.
To accommodate these, specific metadata standards for geographic information have
developed over the years.
UNDER
In 1994 the Federal Geographic Data Committee (FGDC) first published a “Content
Standard for Digital Geospatial Metadata”. This gained wide use, particularly within the
USA, but others also developed with the growth in use of digital geospatial data.
The International Standards Organisation (ISO) Technical Committee 211 – Geographic
information / Geomatics (TC211) undertook work to harmonise a number of these “
de
facto” standards, and in 2003 released the ISO 19115 standard for “Geographic
INFORMATION
Information – Metadata”.
This ISO standard has since been actively managed and revised by TC211, and is widely
recognised in many countries as the national standard to be used for recording metadata
for geographic information:
RELEASED
• ISO 19115 is the official standard adopted by Standards New Zealand and
Standards Australia (AS/NZS ISO 19115.1:2015 is the current joint standard);
• the FGDC has retired its content standard in favour of ISO 19115;
• the International Hydrographic Organization’s S-100 metadata standard for
OFFICIAL
hydrographic, marine and related geographic data is based on the ISO 19000
series.
Current state
THE
ISO metadata
The latest AS/NZS ISO 19115 standard was published in 2015 (superseded the previous
2005 standard AS/NZS ISO standard and 2007 regional profile a.k.a. the “ANZLIC
Metadata Standard” (named after the Australia New Zealand Spatial Information Council
which adapted an ANZ regional profile from the core ISO standard)).
Metadata Contents Guidance – for key resilience and climate

Land Information New Zealand © Crown Copyright
Creating metadata records can be a complex and time-consuming business, and
generally requires supporting software tools to be in place.
While tools were put in place to support the use of the 2007 ANZLIC profile of the
standard, tools and best practices have yet to emerge to support the use of the 2015
version (there is currently an ANZLIC Metadata Working Group looking at this).
The result is that there is a lag in the adoption and use of the new standard. This means
that in addition to the legacy metadata already created to the 2007 standard, metadata
for new dataset is still being created to the 2007 profile.
This is not a significant practical problem; the 2007 standard is forwardly compatible,
and generally still fit-for-purpose.
This situation (lack of tools and best practice guidance) makes it difficult to recommend
use of the current standard. For that reason, until such a time when tools are in place to
ACT
support the newer standard, we recommend that users work with the tools to hand and
create metadata using the previous version.
General metadata
We want to make the key datasets for resilience and climate change easy to find, and
freely and openly available. The place to publish details of public data is
data.govt.nz, the
New Zealand Government’s open data catalogue. UNDER
Any data published through
data.govt.nz has to be described by an accompanying
metadata record. The scope of the content for these metadata is much less extensive
than the full scope of the ISO standard allows. However, it still covers much of the most
critical information.
Additionally, the data.govt.nz team provides tools and support to make the process of
publishing data easy
(https://data.govt.nz/manage-data/).
INFORMATION
Because the data.govt.nz metadata format does not explicitly allow for the provision of
information on data attributes, and is limited in how other critical elements of information
specific to geospatial data can be represented, we recommend that metadata is created
using the ISO standard. A version of this can then easily be brought in, in a cut down
RELEASED
form, to the data.govt.nz catalogue.
Minimum requirements
Table 1 shows the minimum set of metadata elements for key resilience geospatial
OFFICIAL
datasets that we consider necessary to enable users to assess a dataset’s fitness-for-
purpose. It lists the metadata element required, a brief definition and guidance as to
what is expected to be recorded. It also references the name and description of the
corresponding metadata element used by the ANZMet Lite tool.
This software tool was developed by ANZLIC to enable users to easily record the most
THE
essential metadata elements using to the 2007 ISO metadata profile. The tool is available
to
download, and though it is no longer supported, its guidance documentation provides
a very good, easy to understand and more expansive explanation of what each metadata
element should contain.
We highly recommend that you refer to this resource:

profile for ArcGIS / ArcCatalog users. It can be downloaded from their website:

Table 2 provides an example of how the minimum metadata elements can be
represented using the ISO:19115:2007 (ANZLIC) standard.
Table 3 compares the ability of each of the three metadata standards (ISO 19115:2007
(ANZLIC), ISO 19115:2015 and Data.govt.nz schema) to represent these metadata
elements.
It is important to note that this document only considers representation of the elements
that we have deemed necessary to allow users to assess fitness-for-purpose. These are
ACT
really are the bare bones of what is required
The ISO 19115 standard itself has a number of metadata elements it considers
mandatory that are not included amongst these (e.g. Topic Category). It also has a
number of elements the requirement for which is “conditional”.
We recommend that in addition to fitness-for–purpose elements, the mandatory ISO
19115 elements are completed, along with the conditional elements where necessary.
UNDER
Also there are other very useful metadata elements that may be appropriate to your
data, such as “Scale” or “Resolution” or explicit “Use Limitations” based on know fitness-
for-purpose for particular purposes. If these are known and easy to record then it is good
practice to do so. The ANZMet Lite
Short User Guide provides a very good summary and
explanation of these elements and we recommend that it is used as a reference to assist
you in preparing your metadata records.
INFORMATION
Mandatory ISO requirements
In addition to the minimum requirements that we have identified to enable users to
assess fitness-for-purpose, the ISO standard has a subset of mandatory metadata
elements for each record. There is significant overlap between these and those we have
RELEASED
deemed a minimum requirement to assess fitness-for-purpose.
Table 1 in the ANZMet Lite Tool,
Short User Guide (last visited 7/5/2019) identifies the
mandatory elements for the ANZLIC metadata profile v1.1. Although these relate to the
2007 standard we recommend that they completed for each metadata record.
OFFICIAL
New and additional mandatory fields are present in the 2015 version of the ISO standard.
However, as best practice guidance and supporting tools have yet to emerge for that
version we recommend, for practical and pragmatic reasons, that the 2007 mandatory
fields are used.

This dataset provides title information (excluding ownership) where there is
a relationship to one or more primary parcels.
ACT
A Record of Title is a record of a property's owners, legal description and the
rights and responsibilities registered against the title.
This dataset does not contain any ownership information so that it can be
freely distributed. If ownership information is required, see the [NZ Property
Title Including Owners](https://data.linz.govt.nz/layer/50805) and [NZ
Property Title Owners](https://data.linz.govt.nz/layer/50806) datasets.
Note: these are restricted access datasets and require you to agree to the
UNDER
[LINZ Licence for Personal Data](https://www.linz.govt.nz/data/licensing-
and-using-data/linz-licence-for-personal-data).
There can be multiple parcels associated with a title, and a title may only
have a part share in a parcel. This means the shape representing the title will
be an aggregation of all parcels that the title is associated with. The ‘spatial
extents shared’ attribute when equal to ‘false’ will indicate that title has
INFORMATION
exclusive interest over all of the shape (this will be case for the vast
majority).
The originating data for parcel/title associations includes some non-official
sources where the official data does not support a link. For more information

Statement
INFORMATION
The function of the Registrar-General of Land is to provide a system, whereby
the ownership of land can be legally evidenced, under which dealings with it
can be effected and recorded.
From the earliest days of colonisation, offices have existed in New Zealand
RELEASED
for the registration of instruments affecting land. To enable a record of
ownership of land to be kept the Land Registration Ordinance was passed by
the Legislative Council of New Zealand on 28th December 1841. This
provided for the setting up of Deeds Registry Offices and prescribed the
method of registering Crown Grants and other Private Deeds relating to Land.
The system is generally known as Deeds Registration System or Deeds
OFFICIAL
System for short.

The Deeds System with modifications continued until the Land Registry Act
1860 was promulgated. After a number of amendments it was replaced by
the Land Transfer System (LT Act 1870 and subsequent acts). This is
ACT
sometimes called the Torrens System, after its originator in South Australia.
Since the 1870 all registration takes place under the Land Transfer System.
The Land Transfer System provides a simple method of registration and in
addition, titles issued under it are guaranteed by the State. The first digital
data was created by the Land Titles Office (a division of the Justice
Department) in the late 1980s - early 90s. This data formed the electronic
land transfer journal and a titles index (Land Title Link). The LTO was
amalgamated with DOSLI and finally LINZ. As Landonline was rolled out, the
paper titles were converted into digital computer registers. The titles
UNDER
conversion project converted 1.8 million "live" titles and imaged 2 million
instruments. Certificate of Titles were replaced by Computer Registers. Both
have since been replaced by Record of Title, with the commencement of the
Land Transfer Act 2017.
