Quarterly Technical Report

July to September 2006

Introduction

At the end of September 2006, there were 27 repositories within the ASDD with a total of 42,828 dataset descriptions available for searching. Statistics are provided for the ASDD covering:

  • web access statistics,
  • gateway statistics,
  • number of records at each repository,
  • reliability of repository,

for the months of July, August and September 2006.

Repositories which have provided descriptions are also listed.

Achievements during past quarter

  • A new PSMA ASDD node has been created but is not part of this report.
  • There are more basic and less advanced searches this quarter than last quarter.
  • Overall there are less searches than last quarter.
  • There are more visitors and less accesses to the ASDD this quarter than last quarter.
  • Some Z39.50 search errors may be caused by poor metadata content. Some metadata discrepancies are highlighted in the advanced results report.
  • Congratulations to; Australian Hydrographic Office - Product Metadata, Australian Hydrographic Office - Publication Metadata, Australian Hydrographic Office - Source Metadata, Bureau of Meteorology and Geoscience Australia for having 100% valid ANZLIC Version 2 metadata.

Gateway Usage

The following statistics are a summary of the ASDD basic and ASDD advanced gateways:

ASDD Basic Gateway

  • 2739 searches were made through the ASDD basic gateway.
  • 1471 single search terms were used.
  • 1268 multiple search terms were used.

The following links provide more details on the monthly basic gateway statistics:

ASDD Advanced Gateway

  • 1920 searches were made through the ASDD advanced gateway.
  • 1118 single search terms were used.
  • 802 multiple search terms were used.

The following links provide more details on the monthly advanced gateway statistics:

Repository Records

The following table lists the repositories, the DTD used, the number of records parsed per repository and the number of XML records that validated some time during October 2006.

Note:

  • The content of the ANZMETA-1.3 metadata records were validated using the RELAXNG schema.
  • These results take a long time to generate and may show different numbers to those of the monthly accesses. This could be due to nodes adding metadata to their repositories, some repositories not properly responding to the Z39.50 queries or not having records available in XML format.
  • "Not available" means that the server did not respond appropriately to the query at the time of investigation.

The ASDD is an essential component of the Australian Spatial Data Infrastructure (ASDI). The gateway to the ASDD is maintained by Geoscience Australia on behalf of ANZLIC - the Spatial Information Council, as part of its broader Australian Government responsibility for the ASDI.
The individual ASDD nodes are implemented by State/Territory jurisdictions, Australian Government agencies, and commercial organisations (for details see all node descriptions). It is the responsibility of individual nodes to maintain their own metadata and nodes in accordance with the ANZLIC Metadata Guidelines and the ASDD Requirements and Standards.
