Research draft, second pass

A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description

Let an agent explain kinds of balls and their uses, describe sport-specific standards and materials, support choosing and maintaining balls, and describe history and play.

A round or roughly spherical object used in sports, games, exercise and play, from footballs, basketballs and tennis balls to medicine balls, exercise balls, floorball and reaction balls, and also solid balls such as iron balls and novelty balls such as rubber band balls; balls are made in many sizes and materials, are standardised for each sport, and are among the oldest toys and sports equipment.

What it is for: Round objects for sport and play.

It can be explain kinds of ball; describe standards and materials; support choosing and maintaining; describe history and play.
