GPlates Markup Language

The GPlates Geological Information Model (GPGIM) is the first, most important step in creating a new, more flexible XML way of representing geological data in a plate tectonics context. The GPGIM provides the fundemental building blocks to enable reconstruction of features through geological time.

To support collaboration spanning a wide range of different technologies, the language used for communication between grid nodes needs the flexibility and careful planning behind GPML. Since GPML uses the Geography Markup Language (GML), ISO 19136, which in turn uses XML, it enables collaborative efforts to apply GPML and plate-tectonic reconstruction to any GML-compliant data available from the grid, such as features encoded with GeoSciML, or linking with the Geologic Time Scale developed for it.
