Dates : June 14-15, 2011

Location: Agropolis, Avenue Agropolis, 34 Montpellier, France

The first OpenAlea workshop took place in June, 2011 in Montpellier, France. This workshop is a forum for exchanges between different scientific approaches for FSPM modelling, to facilitate the sharing of software components and the emergence of data standards and to share components between the different modelling groups involved in the development of the OpenAlea platform.

This workshop is open to all the developers, modelers and users of the OpenAlea platform and its components.

Main topics

• Digitizing Plant architecture
• Statistical analysis
• Ecophysiological modelling
• Plant reconstruction and simulation

Two round tables have been organized about OpenAlea development roadmap and interoperability between software platform in plant modelling.
