This document discusses several existing ontologies for modeling restaurant menus and food data on the semantic web: - Schema.org allows menus to be attached to restaurants as text or URLs but does not link individual menu items. Recipe classes could be used instead. - RPI has published a Wine ontology and food ontology that could describe menu items. They also held a Food Semantic Web meetup to discuss ontology development. - LOV includes a vocabulary focused on nutrition characteristics of food. - Locu is a platform that enables multi-channel dissemination of data for restaurants and similar businesses. - LinkedFood, from TU Berlin, aims to link food data on the semantic web.
