Integrating Product Classification Standards into Schema.org: eCl@ss and UNSPSC on the Web of Data

This paper details a novel approach for using product classification standards in Web data markup in Microdata and JSON-LD syntax that does not require the availability of proper Web ontology variants of the underlying standards. Our proposal has already been integrated into the official version of schema.org (in use by Google and major search engine operators) and can be readily used for research and business applications.
