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 Wagyu, relay breeds, history, grading, regional brands and international production from animal science and food labelling sources, describe the named breeds and flag brand instances, and distinguish Wagyu from Kobe beef as a brand, Angus, generic marbled beef and crossbred wagyu labels.

Any of the Japanese beef cattle breeds, literally Japanese cattle, comprising four breeds named in registry aliases: Japanese Black, the most numerous and known for intense marbling, Japanese Brown, Japanese Shorthorn and Japanese Polled, along with native cattle such as Mishima cattle, a protected natural monument; regional brands such as Kobe, Matsusaka and Omi beef, sometimes called the Three Great Wagyu, are instances with brand rules rather than breeds, and lists vary. Japanese beef is graded by the Japan Meat Grading Association for yield and quality, with A5 the highest, and Wagyu genetics exported before restrictions underpin herds in Australia and the United States, where crossbred beef may be labelled wagyu under local rules, so labelling claims should be checked.

What it is for: High-value beef production.

It can be explain breeds; relay grading and brands; describe named breeds and brand instances; relay labelling rules.

What the second pass must settle

  • The registry alias Three Great Wagyu should be moved to brand entries
  • Should each breed be a separate entry?
  • How should international labelling rules be linked?
