Writing Workflow Blocks
Workflow blocks can be written in one of several languages: Java R Octave Native executables
We are going to add: Javascript Python
Writing Workflow Blocks Written using a desktop application:
Issues with the block designer tool Number one source of problems
Needs correct XML files creating Dependencies need to be specified Needs Java installed Issues with the proxy Getting updates out is problematic Users want their familiar Java IDE for Java blocks
