Decided that rtnDataFlow was a pain to type so the project name is now rtndf. It’s part of the usual gyrations at the start of a new project – things don’t settle down until there’s a lot of code to change and inertia sets in. The trick is making the right decisions at this stage. For example, the pipeline message format was too limited so it has also been generalized with data and metadata separated into different sections of the JSON message. The Python files for the current Pipeline Processing Elements (PPEs) have been restructured to make it a bit easier to add new ones.
