Australian Spatial Data Directory (ASDD)
Quarterly Technical Report
January to March 2000
Introduction
This quarterly report provides a technical status of the
Australian Spatial Data Directory (ASDD). ERIN, Environment
Australia, is coordinating the technical implementation of the
directory. At the end of March 2000, there were 21 nodes within
the ASDD with a total of 38,582 dataset descriptions available
for searching. Statistics are provided for the ASDD covering
number, compliance and reliability of nodes, number of hits and
records per node for the months of January, February and March
2000.
Achievements during past quarter
The Australian Antarctic Data Centre and the Australian
Hydrographic Office were established as nodes of the ASDD.
Expected during next quarter
Installation and configuration of the Metastar gateway
software is planned for the next quarter. The latest version of
this software will allow for additional functionality to be added
to the interface.

The following table lists the nodes and the number of records
per node that were accessible at 31 March 2000.
