  * **##instances/##** (optional) - contains the controlled metadata instances (JSON-LDs) for selected schemas of the respective metadata model. The sub-directory of the "instances" folder should follow the same structure as the "schemas" folder with an additional sub-directory for each schema. The file names of the controlled instances should be written in lowerCamelCase and state the simple, human-readable identifier of the instance (e.g., **##homoSapiens.jsonld##** for the controlledTerms schema **##Species##**).
  * **##version.txt##** (required) - states the identifier of the version branch (e.g., **##v1##**) of the respective metadata model.
  * **##README.md##** (required) - contains a short content description of the respective metadata model.

  === The openMINDS vocabulary ===
  (% style="text-align: justify;" %)
--Located under the folder **##vocab##** in the main openMINDS GitHub directory, the openMINDS vocabulary is semi-automatically gathered and stored in dedicated JSON files ([[**##types.json##**>>https://raw.githubusercontent.com/HumanBrainProject/openMINDS/v2/vocab/types.json||rel="noopener noreferrer" target="_blank"]] and [[**##properties.json##**>>https://raw.githubusercontent.com/HumanBrainProject/openMINDS/v2/vocab/properties.json||rel="noopener noreferrer" target="_blank"]]). The openMINDS integration pipeline makes sure that both files are updated with each commit to any of the GitHub repositories for the openMINDS metadata models. With that, the openMINDS vocab reflects always an up-to-date status of the general attributes of existing **schemas** and **properties** across all openMINDS metadata models, while providing the opportunity to centrally review and maintain their consistency. In addition, this design allows us to centrally define and maintain multiple references to related schemas and matching schema properties of other metadata initiatives. How this works in detail is explained in the following.
