Dataflow - OpenAlea

OpenAlea
Development strategy for
OpenAlea
C. Pradal

Context
Multi-disciplinary domain
–It involves a variety of disciplines and
expertise.
Low Reusability
–Large models are built from smaller parts
–Reusing existing software is complex
•Different OS, different programming languages
•No common standards or data-structures
Building models is expensive
–Development
–Validation
–Distribution, Documentation, Training

OpenAlea design principles
Language centric
–Common modeling language
–Glue language
Component architecture
–Dynamic composition
–High-level dataflow approach
Visual programming
–Graphical model representation
–Automatic GUI generation
Shared deployment tools
–Build, packaging, distribution,
installation, upgrade
Multi-platform
–Linux, Windows, Mac OS X
