# Schema Sometimes having an id and value data type is not enough. Many times you want to extend a bit, add one extra number you can enter, or add some image that you can fetch from your mobile app. Are you forced for such a change to use [Collection](/dashboard/database/collections.md) rather than taxonomy? Well, if the extension is simple, we have you covered. --- # 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.codemash.io/dashboard/database/taxonomies/schema.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.
