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.

This paper describes the technical challenges of a project to expose a major share of the European building and construction materials market on the basis of the GoodRelations Web vocabulary for e-commerce. This allows for the fine-grained search for products, suppliers, and warehouses for any building-related sourcing needs. Because building materials show a very high item specificity, they are very interesting for new types of search. The result of this project is one of the largest and richest public datasets for a well-defined trade sector that is available on the Semantic Web.

The interdisciplinary nature of the Semantic Web and the many projects put forward by the community led to a large number of widely accepted serialization formats for RDF. Serialization formats are generally transducible among themselves given that they are commonly based on the RDF model. In this paper, we present a RESTful Web service that provides features to accommodate frequent needs of Semantic Web developers, namely a straightforward user interface, persistent URI links for easy sharing, cool URI patterns, and content negotiation using respective HTTP headers.
