Template:Format license
Works out the appropriate link for creative commons licenses (relatively robust to how the text is formatted). Anything not starting "CC" won't be formatted as it's assumed it's not a creative commons license.
Usage edit
The template will ignore case and dashes. If no number is specified, it'll be assumed to be version 4.0.
{{Format license|cc by 4.0}}→ cc by 4.0{{Format license|cc by}}→ cc by{{Format license|cc-by-sa 3}}→ cc-by-sa 3{{Format license|CC BY}}→ CC BY{{Format license|public domain}}→ public domain
