An RDF graph is, at its core, just a set of statements consisting of subjects, predicates and objects. Nevertheless, since its inception practitioners have asked for richer data structures such as containers (for open lists, sets and bags), collections (for closed lists) and reification (for quoting and provenance). Though this desire has been addressed in the RDF primer and RDF Schema specific...

In this paper, we propose a novel framework for RDF stream processing named PRSP. Within this framework, the evaluation of C-SPARQL queries on RDF streams can be reduced to the evaluation of SPARQL queries on RDF graphs. We prove that the reduction is sound and complete. With PRSP, we implement several engines to support C-SPARQL queries by employing current SPARQL query engines such as Jena, g...

The growing importance of RDF as a tool for describing information on the Web has risen a number of interesting works regarding the management of RDF documents. The effective management of RDF data has been an increasingly pressing active area of the current research. However current data management solutions for RDF data present the following shortcomings: (i) they often define new query langu...

In this paper, we will discuss the proposed recommendation (March 1999) for an RDF Schema Specification and compare the approach taken in this specification to conventional meta data models. We will point out several pecularities in the RDF schema specification compared to more conventional approaches, which are basically due to the dual role of properties such as subclass and domain both as pr...

The aim of the Edutella project is to provide a peer-to-peer infrastructure for educational material retrieval using semantic web meta-data descriptions of educational resources. Edutella uses the semantic web meta-data description languages RDF and RDF-Schema for describing web resources. The aim of this work is to wrap the Edutella infrastructure with a functional mediator system. This makes ...

Nowadays, the RDF data model is a crucial part of the Semantic Web. Especially web developers favour RDF serialization formats like RDFa and JSON-LD. However, the visualization of large portions of RDF data in an appealing way is still a cumbersome task. RDF visualizers in general are not targeting the Web as usage scenario or simply display the complex RDF graph directly rather than applying a...

RAP RDF API for PHP is a Semantic Web toolkit for PHP developers. It offers features for parsing, manipulating, storing, querying, serving, and serializing RDF graphs. RAP was started as an open source project by the Freie Universität Berlin in 2002 and has been extended with code contributions from the Semantic Web community. Its latest release (V0.9.1) includes among others: a statement-centr...
