Processing while ingesting

DaCHS allows you to process your data while it is being ingested -- i.e., inside your RD; and that can be done in different levels, from variables type casting to units conversion to complex,multiple variables computing. For the simple/common ones (e.g, units conversion), DaCHS even provides you an API; for more complex tasks, you can define your custom python code.

In your RD there are a couple of places you can trigger such processing calls. One of these places is in the rowmaker element, inside data block [1].

apply elements allow you to embed python code.
