The main methods for customising Source are through PluginsFunctions and using the Command Line Runner.

Source is built upon TIME, a general purpose modelling system. TIME is a software framework for developing eco-hydrological models based upon the Microsoft .NET framework. It is designed to support the creation, testing and end-user delivery of environmental simulation models.

Supports the management, manipulation and presentation of a variety of data types, as well as support for testing, integrating and calibrating simulation models.

TIME Underpins a range of spatial and temporal modelling systems including a number of toolkit models (www.toolkit.net.au)
