The Web of Data for E-Commerce in Brief

Full-day tutorial


A Hands-on Introduction to the GoodRelations Ontology, RDFa Authoring, Google Rich Snippets for Products, Yahoo! SearchMonkey, and Linked Open Commerce

The GoodRelations ontology is one huge success story of applying Semantic Web technology to business challenges. In this tutorial, we will (1) give a comprehensive overview and hands-on training on the conceptual structures of the GoodRelations ontology including patterns for ownership and demand, (2) present the full tool chain for producing and consuming GoodRelations-related data, (3) explain the long-term vision of linked open commerce, (4) describe the main challenges for future research in the field, and (5) discuss advanced topics, like access control, identity and authentication (e.g. with WebID); micropayment services (like Payswarm), and data management issues from the publisher and consumer perspective.
