RDF, a simple yet expressive data model, is widely

                 recognised as the foundation for the Semantic
                 Web. We revisit the RDF specification and analyse
                 five problems: literals are not addressable, blank
                 nodes are not addressable, reification is not
                 semantically recognised, language tags are not
                 addressable, and language tags can not be combined.
                 We introduce SiRDF, a simplified data model with
                 fewer modelling elements that overcomes the
                 mentioned problems, and formally show its semantic
                 equivalence to RDF. Based on the lessons of SiRDF we
                 recommend a restricted usage of RDF that solves the
                 mentioned problems while fully adhering to the
                 original RDF specification.
