I've licensed it under MIT. I considered CC0 or Unlicense so the license wouldn't need to be copied, too, but those licenses wouldn't hold up in Germany.

Anyway, there are two ways this schema can be used in editors.

1. editor workspace settings. I don't know how Rider handles it, but VSCode would need the following:

{
  "json.schemas":  [
    {
      "fileMatch": [
        "**/modinfo.json",
        "**/assets/**/modinfo.json"
      ],
      "url": "https://raw.githubusercontent.com/BinToss/VintageStory.ModInfo.schema/main/VintageStory.ModInfo.schema.json"
    }
  ]
}

2. $schema property in the modinfo.json e.g.

{
  "$schema": "https://raw.githubusercontent.com/BinToss/VintageStory.ModInfo.schema/refs/heads/main/VintageStory.ModInfo.schema.json"
}

Ideally, Anego Studios would generate an official schema for users to validate against.
