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.
