# DataRegistry DataRegistry is a collection that link generators to each other. This is a powerful tool in the creation of your terrains, as this makes it possible to depend the behaviour of terrain elements on other elements. For example, it makes sense to add Mushroom objects only on the grass and not on the road. With a DataRegistry this becomes trivial. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter: ``` GET https://docs.moonlander.ai/explore-topics/dataregistry.md?ask= ``` The question should be specific, self-contained, and written in natural language. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
