21 21  All openMINDS metadata models use a light-weighted schema template syntax for defining the metadata. The correspondingly formatted schema files use the extension: **##.schema.tpl.json##**.

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 it 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). Please find in the following a full documentation of the openMINDS schema template syntax and how it needs to be interpreted.

33 +All openMINDS schemas have to have a **##"_type"##** to be recognized as target templates. In other words, the **##"_type"##** is used to define the openMINDS namespace of a corresponding schema using the following naming convention:
30 30  
35 +(% style="text-align: center;" %)
36 +**##"_type": "https:~/~/openminds.ebrains.eu/<<schema-model>>/<<schema-name>>"##**,
37 +
38 +(% style="text-align: justify;" %)
39 +where **##<<schema-model>>##** has to be replaced with the label of the openMINDS metadata model the corresponding schema belongs to and **##<<schema-name>>##** exchanged with the label of that schema.
40 +
41 +(% style="text-align: justify;" %)
42 +If an openMINDS schema template file //DOES NOT// define a **##"_type"##**, it is interpreted as a context template which requires an extension to become a target template.
43 +
44 +(% style="text-align: justify;" %)
45 +Context templates are and should be used when multiple openMINDS schemas (target templates) have the same subset of properties. This common subset of properties can then be defined within a single context schema instead of each target template which facilitates the long-term maintenance of these properties.
