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 handle paper as a material with grammage, size, fibre source and recyclability, separate from documents and from card-based games.
A thin sheet material made of cellulose pulp derived mainly from wood, rags or certain grasses, used for writing, printing, packaging and hygiene.
What it is for: Writing, printing, packaging, wrapping and hygiene products.
It can be write and print on it; fold, cut and package with it; recycle it; specify it, by size, weight and finish.
Distinguishing features
Made of cellulose fibres
Specified by grammage and size
Recyclable a limited number of times
The paper as a document is a separate entry
What it looks like
Thin flexible sheets, usually white, in standard sizes such as A4 or Letter; card and board are heavier.
Physical character
grammage: 35-300 g/m2 - office paper 80, card 160-300
