Prologue

I keep six honest serving-men (they taught me all I knew);

Their names are What and Why and When

and How and Where and Who.

- Rudyard Kipling, “The Elephant’s Child” 1902.

These six questions are tools to gain knowledge.

In science, two important questions are “How” and “Why” things are related.

Discovery processes investigate relationships among things.

Ontologies are systematic tools for recording knowledge and documenting relationships among things.

Ontomatica integrates knowledge and informatics for foods, agricultural commodities, agrochemicals and pharmaceuticals to present important relationships among them.
