Quarterly Technical Report |
October to December 2005 |
Introduction
At the end of December 2005, there were 26 repositories within the ASDD with a
total of 40,266 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 October, November and December 2005.
Repositories which have provided descriptions are also listed.
Achievements during past quarter
- Murray-Darling Basin Commission came back on-line in November 2005.
- The ASDD Gateways were not available and couldn't connect to most of the
ASDD nodes at around 9:30 am on 29nd December 2005. This was caused by
Geoscience Australia's Internet Service Provider having an internet connection
problem. This would indicate that most of the ASDD nodes were down and hence the
reliability results for October were affected. The reliability reports have been
adjusted to correct this problem caused by the outage.
- Except for the NT Spatial Data Directory node all of the ASDD nodes appear
to be responding
properly to the ASDD advanced search queries except in the case of
badly formed metadata records.
- There are less basic and more advanced searches this quarter than last
quarter.
- Overall there are more searches than last quarter.
- There less visitors and more 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;
Bureau of Meteorology and
South Australian Spatial Information Directory
for being available all of the time.
-
Congratulations to;
Bureau of Meteorology,
Geoscience Australia,
Murray-Darling Basin Commission and
Queensland Department of Natural Resources and Mines Spatial Data,
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
- 2690 searches were made through the ASDD basic gateway.
- 1349 single search terms were used.
- 1341 multiple search terms were used.
The following links provide more details on the monthly basic gateway statistics:
ASDD Advanced Gateway
- 3058 searches were made through the ASDD advanced gateway.
- 1526 single search terms were used.
- 1532 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 January 2006.
Note:
- The content of the ANZMETA-1.3 metadata records were validated using the
RELAX NG 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.
- 94% of the ASDD records were available in XML format for validation.
This is less than last quarter.
- 56% of XML records that were parsed are valid. This is more than
last quarter.
- 7 repositories have 100% valid records, which is the same as last quarter.
- 21 repositories are using or partially using ANZMETA-1.3.DTD or it's
extension, which is more than last quarter.
- "Not available" means that the server did
not respond appropriately to the query at the time of investigation.
