Z-alert - new or modified ASDD metadata records: December 2001

The Australian Spatial Data Directory (ASDD) is a group of separate distributed nodes. Each node is a powerful search system managed by a data custodian. Each node is a collection of uniform dataset descriptions (ANZLIC metadata records). Each dataset description concisely describes a certain spatial dataset (a discreet package of location-based data). Each such record often provides links to further detail and may provide an interface to the actual data. You can now conduct searches via the main ASDD web gateway to discover these specific updated metadata records.

Summary: found a total of 263 new or updated records at 23 nodes.

Explanatory notes:

Warning: This application is a robot that contacts each node in turn and conducts the search. You may see problems with some of the remote search services, due to server configuration and data management issues. That is the responsibility of each distributed search node. All that we can do is to attempt to detect and explain these inter-operability issues.

A maximum of 50 record titles are listed from each node.

No response from node

- their Z39.50 search service could not be contacted (e.g. machine is off-line, server is not running, very busy server, network congestion) see Status of ASDD Nodes

Unsupported Use Attribute: 1012

- their Z39.50 search service is not configured to respond to searches using the "Metadata Date" attribute (metd=1012)

Cannot conduct search

- their Z39.50 search service failed to carry out the search

- the most probable causes are that they are using server software that is way out-of-date, or their server is poorly configured

Cannot present titles

- their Z39.50 search service failed to present the list of results

- the most probable causes are that they are using server software that is way out-of-date, or their server is poorly configured

Cannot connect

- our robot cannot connect to their server (there seems to be some drastic inter-operability problem)

Results are consistently zero hits, yet i know that there are modified records

- server configuration and data management issues - many possibilities

- e.g. their metadata records are not properly updated, see the "Metadata Date" field

- e.g. their metadata records have not been properly validated to ensure reliable structure and content

- e.g. their search server is poorly configured, and only partially responds to the date search

Other notes

- early in the month, the record counts could be zero of course (look at the date generated below)

- sorry, the distinction between Updated and New cannot be determined, as the ANZLIC metadata would need a "Metadata Revision Date" field and a "Metadata Publication Date" field, rather than a solitary "Metadata Date" field

- the history summaries prior to 2002-03 will have slightly skewed results, because they started being recorded on that date and were generated for the past (e.g. a document that was updated in 2001-09 and again in 2001-11 will only get recorded for the latter)

- news and notes about the Z-alert ASDD service

Who to contact about suspected problems

- the results of all searches depend on proper configuration of the remote search server by the data custodian

- See ASDD node descriptions for their contact details

Perhaps you want to build your own network service based upon automated use of the structured log and summary files that are generated by this service - please contact IndexGeo Pty Ltd.
