About
The Open Graph protocol is a web metadata standard that defines how webpages are described as structured objects for use in social graphs and enables their consistent representation.
It specifies a set of 
HTML meta properties that start with "og:" (such as og:title, og:type, og:image, and og:description) to add semantic meaning to a page's content and control how that content should be represented.
The Product Types Ontology is an e-commerce classification vocabulary that provides standardized definitions for product and service types used in structured data markup.
It contains around 300,000 product and service type definitions organized in a hierarchical taxonomy, extends the Schema.org and 
GoodRelations vocabularies, and enables merchants and marketplaces to describe product semantics more precisely for search engines, catalogs, and commerce applications.
