TLDR
The new Semantic Web recommendations for RDF, RDFS and OWL have, at their heart, the RDF graph, and Jena2, a second-generation RDF toolkit, is similarly centered on the R DF graph.Abstract:
The new Semantic Web recommendations for RDF, RDFS and OWL have, at their heart, the RDF graph. Jena2, a second-generation RDF toolkit, is similarly centered on the RDF graph. RDFS and OWL reasoning are seen as graph-to-graph transforms, producing graphs of virtual triples. Rich APIs are provided. The Model API includes support for other aspects of the RDF recommendations, such as containers and reification. The Ontology API includes support for RDFS and OWL, including advanced OWL Full support. Jena includes the de facto reference RDF/XML parser, and provides RDF/XML output using the full range of the rich RDF/XML grammar. N3 I/O is supported. RDF graphs can be stored in-memory or in databases. Jena's query language, RDQL, and the Web API are both offered for the next round of standardization.read more

The OWL API: A Java API for OWL ontologies
Matthew Horridge,Sean Bechhofer +1 more
TL;DR: The OWL API is a high level Application Programming Interface (API) for working with OWL ontologies that supports parsing and rendering in the syntaxes defined in the W3C specification; manipulation of ontological structures; and the use of reasoning engines.

Hexastore: sextuple indexing for semantic web data management
TL;DR: This paper proposes an RDF storage scheme that uses the triple nature of RDF as an asset, which confers significant advantages compared to previous approaches for RDF data management, at the price of a worst-case five-fold increase in index space.

Semantic Wikipedia
TL;DR: This paper provides an extension to be integrated in Wikipedia, that allows the typing of links between articles and the specification of typed data inside the articles in an easy-to-use manner, and presents the design, implementation, and possible uses of this extension.

RDF Vocabulary Description Language 1.0 : RDF Schema. W3C Proposed Recommendation
TL;DR: The Resource Description Framework (RDF) as mentioned in this paper is a general-purpose language for representing information in the Web. This specification defines a vocabulary for this purpose and defines other built-in RDF vocabulary initially specified in the RDF Model and Syntax Specification.

The Description Logic Handbook
TL;DR: This introduction presents the main motivations for the development of Description Logics as a formalism for representing knowledge, as well as some important basic notions underlying all systems that have been created in the DL tradition.
Rdf vocabulary description language 1.0 : Rdf schema
TL;DR: This specification describes how to use RDF to describe RDF vocabularies and defines other built-in RDF vocabulary initially specified in the RDF Model and Syntax Specification.

Using an Expressive Description Logic: FaCT or Fiction?
TL;DR: This paper describes a sound and complete tableaux subsumption testing algorithm for a relatively expressive Description Logic which, in spite of the logic’s worst case complexity, has been shown to perform well in realistic applications.
