+# Attribute Types
+
+The Spacialist provides a big variety of different attribute types that can be used inside your [Data Model](/user/data-model).
+Named versions of those *Attribute Types* are used to populate the [Entity Types](./entity-type).
+
+In the next section we'll introduce all available attribute types, what they are used for and how the import data has to be formatted.
+
+
+## Boolean
+
+Used for single checkbox to represent the binary values `true`and `false`.
+
+### Import Format
+
+When importing only truthy values will be considered. When cells are empty those are considered as `false`.
+
+The values that are considered true are:
+
+- `x`
+- `t` or `true`
+- `w` or `wahr` 
+- [numeric values](https://www.php.net/manual/de/function.is-numeric.php) > 0
+
+### Date
+
+Represents a single date attribute, that is rendered with a default calender input field in the application.
+
+## Import Format
+
+It only accepts dates in the format `YYYY-MM-DD`: e.g. `2024-10-30`
