OpenEarth is a workflow, and one free instance of that workflow
Tools: internal + external: anything too small for separate B&O
repos.deltares.nl
svn.oss.deltares.nl
- Share with entire Deltares
- Share with the entire world
- Marketing umbrella
Communities: for science we can: 400 million
Communities: developers formerly known as users

•
Wikipedia’s 1 % rule:
• 100 visitors: only 1 contributes
• many users = many contributions
• 1% of 400 million = 4 million
• provided the workflow is organized smoothly
Is the Delta tools community big enough ?
