HowToSupply

HowToSupply is a HowToItem subtype for supplies consumed during a HowTo: paint, lumber, screws, ingredients, fabric. (For tools the reader keeps, use HowToTool.)

It adds 1 direct property:

  • estimatedCost (MonetaryAmount or Text): expected cost of the supply, with currency.

Inherits requiredQuantity (QuantitativeValue or Text) from HowToItem — always pair a supply with a quantity so the reader knows how much to buy.

Common HowToSupply mistakes

Mistakes that pass validation but silently fail to earn rich results or mislead consumers walking the graph. Avoid these and your markup will be ahead of most sites in the wild.

  1. 01

    HowToSupply for tools kept afterwards

    Wrong
    HowToSupply for a clamp or drill
    Right
    HowToTool for tools; HowToSupply for consumables

    The distinction matters for shopping-list generators: supplies go on the list every time; tools only once.

  2. 02

    Omitting requiredQuantity

    Wrong
    HowToSupply with just a name
    Right
    Always pair with requiredQuantity so shopping-list generators can aggregate

    Without quantity, a reader cannot buy the right amount.
