Survey Article
Resource Description Framework (RDF) is seen as a solution provider in today's landscape of knowledge representation research. This survey outlines RDF, version 1.1, the W3C Recommendation for knowledge representation on the World Wide Web. In this article, we review and present works from RDF v1.0 and v1.1 implementations. We also provide insights on the reification, blank nodes and entailments. This article surveys current approaches, tools and applications for mapping from relational databases to RDF and from XML to RDF. We discuss RDF serializations, including formats with support for multiple graphs and we analyze RDF compression proposals. All approaches are presented in tabular format concisely and are grouped under a classification scheme. Moreover, the article provides an empirical study about usage of different RDF model elements as well as RDFS vocabulary terms. Finally, we present a summarized formal definition of RDF 1.1 and emphasize changes between RDF versions 1.0 and 1.1.
