This can be the most interesting part, requiring choices for
- suite durability
- common libraries coding
- ensuring maintainability
The CDP client provides an environment where CDP variables, aliases and functions are global entities. Choosing ksh to design a suite will lead to similar concepts and practices. Choosing the Python language can lead to deeper changes.
Milestones are:
- the expanded definition file generation
- the expanded definition file load into ecFlow server
- running the (e)suite
- eventually, expanded definition files played into SMS server, and run as (e)suite
