Quarterly Technical Report |
April to June 2004 |
Introduction
At the end of June 2004, there were 26 repositories within the ASDD with a
total of 37,511 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 April, May and June 2004.
Repositories which have provided descriptions are also listed.
Achievements during past quarter
- The ASDD and Metadata Workshop
was held on the 17th and 18th of May 2004.
- The new ASDD web site replaced the old ASDD web site on 2004-06-30.
Comments about this site are welcomed via the "feedback" link.
- A new node
Australian Hydrographic
Service - Source Metadata was created.
- The "Murray-Darling Basin Commission Documents" node is still off line
while it is changing Internet service providers.
- The new "ACT Geographic Data Directory" node has 100% valid
records.
- The "Other Commonwealth Data (hosted by BRS)" node now has 100% valid
records.
- The "Queensland Department of Natural Resources and Mines Spatial
Data" node now has 100% valid records.
- There are less visitors and less accesses to the ASDD this quarter than
last quarter.

Gateway Usage
The following statistics are a summary of the ASDD basic and ASDD power
gateways:
ASDD Basic Gateway
- 4787 searches were made through the ASDD basic gateway.
- 4047 single search terms were used.
- 740 multiple search terms were used.
The following links provide more details on the monthly basic gateway statistics:
ASDD Power Gateway
- Approximately 716 searches were made through the ASDD power gateway.
- Approximately 431 single search terms were used.
- Approximately 285 multiple search terms were used.
The following links provide more details on the monthly power 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 July 2004.
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.
- Only 89% of the ASDD records were available in XML format for validation.
This is more than last quarter.
- 99% of XML records that were parsed are valid.
- 12 repositories have 100% valid records, which is more than last quarter.
- 14 repositories are using or partially using ANZMETA-1.3.DTD or it's
extension, which is the same as last quarter.
- "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.
