Slide adapted from Boyan Brodaric – Natural Resources Canada
• Water Resources• Bureau of Meteorology – legislative mandate on
water data• 300 data providers• Dozens of data products
• What format?• 95% say Comma Separated Values – what about
relationships?• Is “T” Temperature, Time, Total, Turbidity?• What about Units of measurement? Temperature,
Kelvin, Centigrade, Fahrenheit?
There is more to standardisation than file formats and legislation
It’s all quite traumatic! How do I make it work for me?

The trouble is…Its about “their” workflow
Making it work for “you”Who are you? Consumer, Provider or both!
Provider
ConsumerStandardise Information modelsStandardise the Query interface
Do not change my internal operations dramaticallyDo not second guess the Consumers workflow
Standardise the Information Models
• Not a storage problem…• User View (Data Products)• Custodian’s View
(Consistency, Efficiency)• Systems View (bandwidth,
query cost)
• Semantics and structure• GML and GML application
schemas
• Tool support• UML, Hollow world and
Fullmoon

Some lessons worth listening too…
• Open Geospatial Consortium • Use OGC as a starting point
• And its information standards…
• And its service interfaces…
• It can be quite a stack of paper!
• OGC breaks problem into specific aspects
• Use it to identify necessary services for your application
• It pays to get assistance from specialists in the community
• use Roadmaps and Guides
• OGC is NOT enough• domain specific vocabularies
required
• Many gateway services do NOT support this
Things to watch out for
• Your data isn’t as consistent as you’d hoped• Data management improvements
• change in business practice!
• Private information models exposed• Simple Features with “labels and values” is not enough• Meaning (semantics) is essential – Community models
• Technology doesn’t quite allow you to jump from what you have to what you need in 1 configurable step…
• Components can be improved
Reality Check!!SEE Grid National Roadshow
“the explorers agreed that the SEEGrid project for interoperability of precompetitive geoscience data was essential when it comes to long term benefits to aid future exploration effort in Victoria.”
• Chris Fraser, Executive Director, MCA Victoria – August 2005
“The Australian Geoscience Council therefore recommends:…
The development of new ways to store and access data and information (such as the SEEGrid) should be embraced…”
• Mike Smith, President, Australian Geoscience Council Submission to Prime Minister's Science, Engineering and Innovation Council
