24 24  Although, as the file extension suggests, this openMINDS schema template syntax is inspired by JSON-Schema, it facilitates or even excludes technical aspects that are generally expected for the openMINDS schemas making them more human-readable, especially for untrained eyes. Behind the scenes, within the openMINDS integration pipeline (cf. below), this schema template syntax is then interpreted and flexibly translated to various formal metadata formats (e.g., JSON-Schema).

90 90  How to define the expected value of a property will be explained for the different property types in the following sections.

109 -In accordance with JSON-Schema, it is possible, though, to further define a selected list of built-in formats that are accepted for the expected string. Supported are all [[built-in formats of JSON-Schema Draft 7.0>>https://json-schema.org/understanding-json-schema/reference/string.html#built-in-formats||rel="noopener noreferrer" target="_blank"]].
