Main Talk summary
Using, mostly Python, the challenge of this project was to offer
within an intranet, a RESTful  'statistical service' powered by R (a
statistical language).   This ‘service’  (to crunch a lot of usage
data from across Australia) had to communicate securely and reliably
with other systems, schedule and prioritize requests of its services,
and of course, enable users to select and filter the data through
interactive graphs in the browser.
The components of this system include, beyond a specialised R package
(CAL-R):
       • MySql as a data store;
       • Django, as the application server dealing with workflow, page
delivery and tracking;
       • Django-Piston, making the whole service available as a
‘RESTful service’ to the business.
       • Connections to R via Pyper (a piping system that maps R
objects into Python objects and vice versa).  T
       • Load and composition of tasks for CAL-R,  controlled by a
queuing/scheduling system based on RabbitMQ and Django Celery
       • Formatting and user manipulation of objects on the page (eg
drag and drop, select etc) is delivered via jQuery (a JavaScript
framework) and
       • Protovis (a JavaScript implementation of ‘ggplot’ style
graphics) renders custom interactive graphs in the browser (note: not
just a pdf!).

Biography
Richard Volpato, born in Italy, studied at ANU and Cambridge (UK)
mostly sociology and social research.  He has also consulted across a
large number of industries, notably forestry, tourism, superannuation,
education, health, religion and urban/regional planning, the last of
which led  (via Zope Corporation) to a successful tender for the
Victorian Government Planning scheme amendments system (ZAPP: Zope
Amendment Production Platform).  His current role at the Copyright
Agency as Manager of Data Quality and Analysis has been to improve
data quality, its value and the systems used to acquire and process it
