OCDS Nightingale 0.0.2

Nightingale transforms flat data from a SQLite database into the Open Contracting Data Standard (OCDS) format, in a configuration-driven approach.

If you are viewing this on GitHub or PyPI, open the full documentation for additional details.

Nightingale transforms data through the following steps:

1. Load flat data from the SQLite database using the selector from the configuration.

2. Read the mapping configuration to understand how to transform the data.

3. Map the data into the OCDS format.

4. Package the data if specified.

5. Write the data to the specified output.
