Dear Open Targets community,

On the [Data Downloads](https://platform.opentargets.org/downloads) page, there are schemas for individual datasets. I am wondering if there is a way to get a combined metadata / schema that covers all datasets available, preferably in a machine-readable format (e.g. JSON, markup language, or something similar)?

Many thanks  
Albert

Dear Albert,

Yes, the schemas displayed on the downloads page are all built based on a JSON file following [croissant](https://github.com/mlcommons/croissant) format, which was specifically designed to make complex datasets ML ready. The JSON file can be accessed on the downloads page by clicking on the croissant button. (more information about the croissant standard can be found [here](https://docs.mlcommons.org/croissant/docs/croissant-spec-1.0.html))

Please let us know if you have further questions.
