Metadata are structured facts that describe information, or information services. Metadata facilitates many things beyond enabling information discovery and access; it also informs about the appropriate use of products and services. Metadata is applicable to anything, not just geographic information. For example, your business card is metadata about you.
The peak organisation for standards development across business, government and society is the International Organisation for Standardisation (ISO). ISO through its Technical Committee for Geographic information/Geomatics (ISO/TC 211), has published an International Standard for Metadata (ISO 19115:2003). ISO 19115:2003 specifies the schema required for describing geographic information and services. It provides information about the identification, the extent, the quality, the spatial and temporal schema, spatial reference, and distribution of digital geographic data. This was subsequently adopted by Standards Australia/Standards New Zealand (AS/NZS ISO 19115:2005).
There was extensive input by Australia during development of ISO 19115:2003, particularly from interests associated with ANZLIC, and as a result this standard incorporates several core metadata elements from the previously published ANZLIC Metadata Guidelines V.2. In August 2007 the ANZLIC Metadata Guidelines V.2 became superceded with the release of the ANZLIC Metadata Profile Version 1.1. This new ANZLIC metadata standard complies with ISO 19115:2003.
ANZLIC works closely with Standards Australia, Standards New Zealand, the Intergovernmental Committee on Surveying & Mapping (ICSM), and PSMA Australia Limited to raise the awareness and uptake of geospatial standards.
The GEN Register is an on-line resource that contains the geographic extents of thousands of geographic objects. These objects range from maps sheets, navigational charts, oceans and rivers, through to States, Territories and Local Government Areas.
