Quarterly Technical Report
October to December 2001
At the end of December 2001, there were 23 repositories within
the ASDD with a total of 31,448 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 2001.
Repositories which have provided descriptions are also
listed.
- A new repository, "WALIS Interragator-Natural Resource
Monitoring", was made available to the ASDD gateway from the
WALIS server.
- There were some name changes to the repositories.
- The "Qld Spatial Data (QSIIS)" was moved to a new
server.
- The "Murray-Darling Basin Commission Documents" is
off line while it is changing internet service providers.
This quarter's statistics for the ASDD Basic and Power
gateways are available for the period 2001-11-29 to
2001-12-29.
More details are available for: 29th September 2001 to
29th December 2001
A summary of those statistics for this period follows:

gateway.
- Approximately 3346 single search terms were used.
- Approximately 434 multiple search terms were used.
The following links provide more details on the monthly
gateway statistics:
ASDD Power Gateway
- Approximately 1294 searches were made through the ASDD power
gateway.
- Approximately 835 single search terms were used.
- Approximately 459 multiple search terms were used.
The following links provide more details on the monthly
gateway statistics:
The following table lists the repositories the DTD used, the
number of records per repository and the number of XML records
that parsed that were accessible at the beginning of January 2002.
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 or some
repositories not providing XML records.
- "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.
- Only 61% of the records parse against a DTD.
- Only 4 repositories are using ANZMETA-1.3.DTD.
- Only 8 repositories have 100% valid records.
