Application Of New Zealand Metadata Standards – Overcoming Potential Shortcomings

Annual Conference

This paper provides an overview of the national metadata standards for three waters and provides a case study describing how the standards were applied to assign criticality ratings to three waters pipelines. The paper discusses potential shortcomings with the standards and discusses how these were overcome whilst retaining the overall intent of the standards.

The Auditor General has observed that “although local and central government authorities tend to have a lot of data, there is little evident to suggest they use the best data to support decision-making.” Across New Zealand data is collected in different ways and described differently. Sometimes the right data to make informed decisions is not captured.

To help address this LINZ and MBIE commissioned the development of the national metadata standards, working with local councils and central government agencies to develop standards for the three waters (potable, waste and storm) networks, and for residential and light commercial buildings.

The standards, that were published in 2017, cover as-constructed data which is information that can be collected when infrastructure is constructed, e.g. physical data such as pipe material. The standards also define common asset management schema for defining and reporting on aspects such as condition, performance, criticality, financial performance.

The standards are intended to provide data consistency across government agencies and local authorities and enable data to be shared, aggregated and analysed in more detail than is currently possible, ultimately, contributing to more informed, evidence based decision making.

This paper will help water authorities understand how the standards can be applied to their organisations in a manner that provides the national consistency intended by the standards whilst addressing the particular characteristics and challenges of individual networks.
