What is MIME type "application/vnd.geogebra.file"?

A MIME type is a string that tells browsers and other tools how to handle a particular kind of file.

application/vnd.geogebra.file is the MIME type for files created by GeoGebra. These files store interactive math and geometry constructions that can dynamically update based on user actions.

• Main use case: Saving interactive mathematical models and geometric figures.
• Dynamic functionality: The file holds instructions that allow algebraic and geometric objects to change in real time.
• It is used in education and research to explore mathematical concepts.
• This MIME type especially applies to modern GeoGebra files typically saved with the GGB extension.

Older GeoGebra files used the GEO extension, coming from GeoGebra 1.0.
