Quarterly Technical Report
October to December 2000
Introduction
At the end of December 2000, there were 22 nodes within the
ASDD with a total of 41,485 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 October, November and December
2000.
Achievements during past quarter
One new ASDD node was made available to the gateway: the
"CSIRO Marine Research" node.
The South Australian node has changed it's location.
The following table lists the nodes and the number of records
per node that were accessible at 31 December 2000.
