Quarterly Technical Report |
October to December 2004 |
Introduction
At the end of December 2004, there were 25 repositories within the ASDD with a
total of 36,977 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 2004.
Repositories which have provided descriptions are also listed.
Achievements during past quarter
- The
RAN Directorate of Oceanography and Meteorology
was off line for a while as the domain servers were being transferred.
- The "Murray-Darling Basin Commission Documents" node is still off line
while it is changing Internet service providers.
- The "WALIS Interragator-Aerial Photography" node now has 100%
valid records.
- The "WALIS Interragator-Bibliographic Data" node now has 100%
valid records.
- There are more visitors and less accesses to the ASDD this quarter than
last quarter.
- The reliability of most of the ASDD nodes appears to have improved.
- Some Z39.50 search errors may be cause by poor metadata content. Some
metadata discrepancies are highlighted in the
advanced results report.
Web Statistics for ASDD
This quarter's statistics for the ASDD are

Gateway Usage
The following statistics are a summary of the ASDD basic and ASDD advanced
gateways:
ASDD Basic Gateway
- 1972 searches were made through the ASDD basic gateway.
- 1087 single search terms were used.
- 885 multiple search terms were used.
The following links provide more details on the monthly basic gateway statistics:
ASDD Advanced Gateway
- 1262 searches were made through the ASDD advanced gateway.
- 662 single search terms were used.
- 600 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
sometime during January 2005.
Note:
- 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.
- 95% of the ASDD records were available in XML format for validation.
This is more than last quarter.
- 96% of XML records that were parsed are valid.
- 11 repositories have 100% valid records, which is less than last quarter.
However, many of the XML errors are minor and can be easily fixed. There
are some hypertext links to the node's reports for those that have
XML parsing errors.
- 17 repositories are using or partially using ANZMETA-1.3.DTD or it's
extension, which is more than the last quarter.
- Some nodes just need to convert their & to the entity character reference
equivalents.
- "Not available" means that the server did
not respond appropriately to the query at the time of investigation.
- "None" means that no DTD was provided in the XML records or no
XML records were available. This is not a Z39.50 problem it is a processing problem.
