Hi Jonathan,

Thanks for your feed back. Your email highlights a few factors
about which some people seem a bit confused.

Geoscience Australia manages the ASDD gateways on behalf of
ANZLIC. Part of this management is providing technical
documentation on how to participate in the ASDD search system
and making sure that the gateways are operating.

However, ANZLIC has control of the overall management of
the ASDD which includes the governance of the jurisdictional
ASDD nodes and their compliance with the ASDD requirements. Geoscience
Australia provides ANZLIC with information whether ASDD nodes are
complying with the requirements but I believe that
ANZLIC has the governance to enforce that compliance.

I will consider your comments and I will address some of them below:

Thanks for your prompt input.

I hope that this helps

John Hockaday

I agree that this is a very important issue. I also believe
that ANZLIC has the jurisdiction to advertise the ASDD. We
at Geoscience Australia certainly try to advertise the ASDD
where ever we can but we only manage the gateways not the
entire ASDD.

Maybe ANZLIC can provide some more advertising or comments
on this?

I think that it is a great idea to link to the ASDD from
the metadata HTML records. However, these records are managed
by the individual nodes which Geoscience Australia has no
control over. Some nodes do make their metadata records
accessible to the web browsers. Maybe ANZLIC can encourage
all the nodes to make their records available to the web
browsers and provide hypertext links to the ASDD.

I invite ANZLIC to respond to this suggestion.

The ASDD gateways use the Z3950 protocol which is ISO 23950.
There is nothing stopping anyone using this protocol to search
the ASDD nodes from their own site. I believe that there
are at least three organisations already doing this. One
just needs to use or develop some software that performs
Z3950 search and retrievals on the ASDD nodes. The
information about the nodes is located at this URL:

All you need is the machine name which is running each zserver,
the port number on which the zserver is running and the
repository name.

Good luck!.

I find this very interesting. Does anyone else feel that
Geoscience Australia should coordinate a national ASDI
registry? Geoscience Australia is always interested in
participating in OpenGIS compliant services however, the
resource requirements have not been estimated nor allocated
to provide a national registry service. If someone can
suggest a method of providing the budget and personnel then
I'm sure Geoscience Australia will certainly consider the
proposal and the management of a registry once it is up and

The ASDD node managers have been asked to provide feedback.
ANZLIC may wish to forward my request for feedback onto the
Jurisdiction managers if they wish. I have no governance
in that area. Geoscience Australia only manages the ASDD
gateways. ANZLIC manages the ASDD as a whole.
