The Geoscience Large Object Store (GLOS) is a database for the storage of models and related digital objects, together with metadata that describes the details of the originating model software. This will allow the models to be re-used by the originating software this presupposes that the software and hardware platforms are still available for use. Longer-term preservation will be achieved through the use of the Geoscience Spatial Framework.

**Mothballed**The Geoscience Spatial Framework (GSF) is a database for the storage of 3D modelled surfaces and volumes, in a data structure that is independent of the originating model software. It is based on the simplest possible spatial unit (the point), which can be obtained from the export formats of most modelling packages. The points are stored as Latitude/longitude pairs referred to the ETRF89 datum, although the elevation does not rigorously conform. Topological information (triangulation) is provided, which indicates how points may form surfaces or volumes. The GSF allows models to be linked to a range of attributes describing their properties and to integrate with other BGS data sets, including metadata.
