Greetings from the Australian National University in Canberra, where Ian
Gorton, from the Pacific Northwest National Laboratory of the US Dept.
of Energy, is speaking on "Towards a Collaborative Scientific Knowledge
Management Platform with Velo". The software has been used for modelling
carbon sequestration and climate change.
Velo is designed for high performance computing. Scientists want to be
able to easily get at their data. Large scientific instruments can
produce large amounts of data quickly. This requires that the
definitions of the data and the requirements ("Scientific
Knowledge-Management Requirements") need to be understood by the people
building the software. Also new applications need to be able to access
old data and applications.
Traditionally, a new software tool would be built for each area of
science. However, this is becoming prohibitively expensive. Just as is
using more package software, so is science.
Velo uses open source software, including MediaWiki and the Alfresco
Content Management System (CMS). These are tools normally though of
being used for e-publishing (the Australian Computer Society uses
Alfresco for keeping its course content).
The Velo approach is an interesting one as it goes some way to unite the
document and data repositories which universities, such as the ANU are
now building. The Australian National Data Service (ANDS), location at
ANU, is building a system for cataloguing and allowing sharing of
research data. But this is separate from the repositories used for the
research papers about the same data. Essentially the same technology is
used to describe the data and the papers and so there is no reason why
they need to be kept separate.
At question time I asked Ian when the software would be freely
available. He replied that the interfaces are now being documents and
the software should be freely available online as open source in ten
weeks time.
