I have a site where users can add their bicycles that they own, and I'm not quite sure how to structure the schema.org data. The bikes are not for sale, only displayed, and there are multiple versions of the same type of bicycle on the site.This is what I'm thinking so far:Member details page:Person-- name-- image-- owns:   -- ownershipinfo (1 per bicycle)      -- name      -- image      -- urlBicycle details page:Thing-- name-- imageI thought about using Product on the member page under owns, and also for the bicycle itself instead of Thing, but I'm under the impression that Product is intended for products for sale on an e-commerce site. So should I use Thing, Product, or something else entirely?
What kind of schema.org classification should be used for user generated content?
