2. Autodesk Topobase File
Plugin file used by Topobase, a program used to manage geospatial information; saved in an XML format and specifies the classes (program objects) to load for the plugin; saved with one or more .DLL files that contain the classes.
Topobase is designed for extensibility in order to suit particular geospatial data management requirements. Therefore, users often create custom Topobase plugins based on their company's needs.
