Primary features

This page lists the capabilities of the system. These features are introduced here and are defined in more detail by the associated stories.

Features inherited from AstroGrid 1

This will be a list of features implemented in the AstroGrid 1 components.

Features added in AstroGrid 2

This is a list of possible features. Some are taken from the Technical scope; others are my own ideas. In later versions of this page, I hope to identify those features that are variously necessary, desirable and feasible.
