The following data types are handled natively by the WikiDB extension. The extension also has a mechanism for adding 3rd party data types, so the type system is fully extensible. If a field is untyped, WikiDB will attempt to guess the type using a system which works even for user-defined types.

wikistring
This is a text string that will be parsed as wikitext when displayed. This is the default type for any fields that don't conform to a more specific type.
- Options: none
- Validation: All values are valid
- Formatting: none (except the automatic formatting done by MediaWiki)
string
This is a literal text string.
- Options: max_length
- Validation: All values are valid
- Formatting: Truncated according to max_length and wrapped in <nowiki> tags.
integer
An integer number. The alias int is also allowed.
- Options: min_value, max_value
- Validation: Must be numeric, must be within range
- Formatting: Non-integer values are rounded. No decimal point is displayed.
number
A real number or integer.
- Options: min_value, max_value
- Validation: Must be numeric, must be within range
- Formatting: Always has a number before and after decimal point (.5 => 0.5, 5. => 5.0). Trailing zeros after the decimal point are removed (5.400 => 5.4). Integers without decimal point are unchanged (5.0 => 5.0, 5 => 5).
link
- Options: none
- Validation: All values are valid
- Formatting: Wraps in wiki braces, if not already present. Adds colon to beginning if the link is to the Image: or Category: namespace, if not already present. For example "Main Page" becomes "[[Main Page]]", and "[[Category:Fish]]" becomes "[[:Category:Fish]]".
image
A link to a page in the Image: namespace.
- Options: width, height
- Validation: All values are valid.
- Formatting: Outputs the image as a small thumbnail, whose size is restricted by the width and height options (if not present, they default to 75px). Images smaller than the specified size are not scaled up.
