The taxonomic frame gives us a placement or position of each and every object, item or substance within our inventory. In our living inventory, these frames are generally made of the accepted classification: animal, vegetable and mineral which have been characterized, categorized, classified and clearly defined for an eon or so at least since the Renaisance.  Genetic traits of animals, even Humans, place us into Kingdom, Phylum, Family and yes, sorry, Class (but not the way 'they' do it). Pedigree can help enumerate value of beef and pork so the taxonomy of bovine and porcine "units" will allow us to simply import the whole taxonomic frame that includes domesticated animals.
