108	108	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.

143	143	In the case that several schemas are highly related and contain a common set of properties, it is possible to define a non-type context-schema with these common properties that can be extended and modified by the group of related schemas. All properties and constraints (e.g. required properties, expected data types) defined in the context-schema are passed on to the schemas extending this context-schema. Each of these schemas can define additional properties, or (if necessary) can overwrite the constraints of the context-schema. In order to state that a schema is extending a context-schema, the following additional key-value pair has to be added to the schema template above:

A good hands-on example, is the context-schema [[ResearchProduct>>https://raw.githubusercontent.com/HumanBrainProject/openMINDS_core/v3/schemas/products/researchProduct.schema.tpl.json||rel="noopener noreferrer" target="_blank"]] which is extended by the following schema set: [[Dataset>>https://raw.githubusercontent.com/HumanBrainProject/openMINDS_core/v3/schemas/products/dataset.schema.tpl.json||rel="noopener noreferrer" target="_blank"]], [[MetaDataModel>>https://raw.githubusercontent.com/HumanBrainProject/openMINDS_core/v3/schemas/products/metaDataModel.schema.tpl.json]], [[Model>>https://raw.githubusercontent.com/HumanBrainProject/openMINDS_core/v3/schemas/products/model.schema.tpl.json||rel="noopener noreferrer" target="_blank"]], and [[Software>>https://raw.githubusercontent.com/HumanBrainProject/openMINDS_core/v3/schemas/products/software.schema.tpl.json||rel="noopener noreferrer" target="_blank"]].

152	152	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"##**.
