Denny,
I would suggest to use https://en.wiktionary.org/wiki/product as that strawman proposal. Because it has 2 levels of Senses. 3. Anything that is produced (contains 6 sub-senses)
To apply Daniel's thinking... I wonder...
his Lexeme Sense = Wordnet Sense ? his Item -> Lexeme - Forms = Wordnet Synset ?
