Implementing ASDD nodes - support and resources

The Australian Spatial Data Directory (ASDD) is currently being developed. The framework is a group of Z39.50 servers (called nodes), which together form a seamless clearinghouse of distributed geospatial data servers.

• Search the Australian Spatial Data Directory
  • use advanced and basic WWW interfaces, more nodes are continually being added
• ASDD technical documentation at Geoscience Australia (the technical coordinating node of the ASDD)
  • explains ASDD architecture, overview of Z39.50 search and retrieve, includes guidelines for setting up nodes with various software, references, options for metadata management, the ANZMETA XML Document Type Definition (DTD)
