u"""The Pokédex schema.

Columns have a info dictionary with these keys:
- official: True if the values appear in games or official material; False if
  they are fan-created or fan-written. This flag is currently only set for
  official text columns.
- format: The format of a text column. Can be one of:
  - plaintext: Normal Unicode text (widely used in names)
  - markdown: Veekun's Markdown flavor (generally used in effect descriptions)
  - gametext: Transcription of in-game text that strives to be both
    human-readable and represent the original text exactly.
  - identifier: A fan-made identifier in the [-_a-z0-9]* format. Not intended
    for translation.
  - latex: A formula in LaTeX syntax.
- ripped: True for text that has been ripped from the games, and can be ripped
  again for new versions or languages

- string_getter: for translation columns, a function taking (text, session,
  language) that is used for properties on the main table. Used for Markdown
  text.

See `pokedex.db.multilang` for how localizable text columns work.  The session
classes in that module can be used to change the default language.
