	114	+All openMINDS metadata models use a light-weighted schema template syntax for defining the expected metadata. Although this schema template syntax is inspired by JSON-Schema, it outsources most schema technicalities to be handled in the openMINDS integration pipeline, making the openMINDS schemas more human-readable, especially for untrained eyes. Within the openMINDS integration pipeline (cf. below), the schema template syntax is interpreted, extended and flexibly translated to various formal metadata formats (e.g., JSON-Schema).

117		-The few remaining customized technical properties which need additional interpretation or translation to a formal schema languages (e.g. JSON-Schema) have an underscore as prefix (e.g., **##"_type"##**). Within the openMINDS integration pipeline (cf. below), the schema template syntax is interpreted, extended and flexibly translated to various formal schema languages. All further specifications of the openMINDS schema template syntax are described below.

	121	+All openMINDS schemas are human and machine-readable text files with the extension **##.schema.tpl.json##** which define the structure and content of correctly instantiated openMINDS metadata instances. Many features are adopted from JSON-Schema.  According to the schema template syntax each schema is defined as a nested associative array (dictionary).

137		-**##"_type"##** defines the schema type (or namespace) with the depicted naming convention, where the label of the respective openMINDS metadata model (e.g., **##"core"##**) and the schema name (format: UpperCamelCase; e.g. **##"Person"##**) have to be specified. Obviously, the schema name should be meaningful and provide some insides into what metadata content the schema covers.

139		-(% style="text-align: justify;" %)
140		-Under **##"properties"##** a nested associative array is defined, where each key defines the property name (format: lowerCamelCase; e.g. **##"givenName"##**). The corresponding value is again a nested associative array defining the expected data **##"type"##** (cf. below) and the **##"_instructions"##** for entering the correct metadata for the respective property.

142		-(% style="text-align: justify;" %)
143		-Under **##"required"##** a list of property names can be provided that are obligatory to be present in a correctly instantiated metadata instance of the respective schema. If none of the properties are required, this key-value pair does not have to be specified.

145		-(% style="text-align: justify;" %)
146		-Now, depending on the expected data type additional constraints can be made for the metadata entry of a respective property. Currently, the openMINDS schema template syntax supports the following data types: **##"string"##**, ##**"integer"##**, **##"float"##**, **##"boolean"##**, **##"array"##** and **##"object"##**.
