What are the reference taxonomies?

The reference taxonomies are downloadable data sets that are used as part of the GEA-NZ framework as a common language to categorise government organisations’ business and technology architecture.

Purpose of the taxonomies

The reference taxonomies can be used to:

  • provide a common language
  • categorise the Government Digital Standards Catalogue
  • promote service, information, system and technology interoperability
  • reduce complexity by abstracting, organising and simplifying complex information sets
  • improve overall consistency and cohesiveness of integrated services, shared services and common capabilities
  • deliver consistent and aligned views of commonly required operational and technological services
  • improve the efficacy, utility and cost effectiveness across government
  • drive ICT and digital efficiencies and transformation programmes, through identification of opportunities for development or reuse of common solutions
  • support the development and delivery of a unified public service
  • support the implementation of the Strategy for a Digital Public Service.

The core taxonomies

The 4 core reference taxonomies are aligned to the 4 core dimensions of GEA-NZ:

  • Business
  • Data and Information
  • Application and Software Services
  • Infrastructure.

The fifth taxonomy, named Other Categories Reference Taxonomy, is used for terms that are not included in the 4 core reference taxonomies.
