The Plan Details

Details about the five-year projected tax revenues and rates are stored in YAML files in the data/01_raw/plans/ folder (link). For a given plan, there should be a separate file for the proposed and adopted versions of the Plan.

There is a specific schema that must be used. See an example YAML file here. This file looks like this:

If the data in the YAML file does not match the schema, an error will be raised when the analysis runs.

Schema
