Rules for Codetables - wmo-im/wmds GitHub Wiki
1. Which editors to use?
Change the tables directly in Github or use Notepad++. Do not use MS Excel to open/alter the csv files, because MS Excel may affect the character encoding.
2. Notation:
The notation must follow the allowed characters for use in URLs specification
This means that a lot of special characters must not be used in the notation (no greek characters, no brackets, they should not start with _, etc.).
Follow the spelling guidelines
