untitled Part I. Getting Started Chapter 1. 1.1. rdf:about Sesame 2 ¶ 1.1.1. Sesame is an open source Java framework for storage and querying of RDF data. Of course, a framework isn't very useful without implementations of the various APIs. Originally, Sesame was developed by Aduna (then known as Aidministrator) as a research prototype for the hugely successful EU research project On-To-Knowledge. Sesame is currently developed as a community project, with Aduna as the project leader. 1.1.2. This user manual covers most aspects of working with Sesame in a variety of settings. The basics of programming with Sesame are covered in chapter-repository-api. chapter-http-protocol gives an overview of the structure of the HTTP REST protocol for the Sesame Server, which is useful if you want to communicate with a Sesame Server from a programming language other than Java. Chapter 2. 2.1. Sesame releases can be downloaded from Sourceforge. openrdf-sesame-(version)-sdk.tar.gz. 2.1.1. 2.1.2. 2.2. 2.3. 2.3.1.

JRDF - An RDF Library in Java OWLIM-Lite Fact Sheet - OWLIM42 - Ontotext Wiki OWLIM-Lite is a high-performance semantic repository created by Ontotext including a native RDF rule entailment engine. It is implemented in Java and packaged as a Storage and Inference Layer (SAIL) for the Sesame openRDF framework. The supported semantics can be configured through rule-set definition and selection. Rule-sets for OWL-Horst [21], unconstrained RDFS [7] with OWL Lite [10] and the OWL2 RL profile [25][26] are included. The key features of the current release of OWLIM-Lite can be summarised as follows: The fastest semantic repository in the World, it can perform non-trivial inference on millions of RDF data statements; Pure Java implementation, ensuring ease of deployment and portability; Compatible with Sesame 2, which brings interoperability benefits and support for all major RDF syntaxes and query languages; Customisable reasoning, in addition to RDFS, OWL Horst, and OWL 2 RL support. OWLIM-Lite is a Java library without user interface.

Mulgara Mereology Mereology has been axiomatized in various ways as applications of predicate logic to formal ontology, of which mereology is an important part. A common element of such axiomatizations is the assumption, shared with inclusion, that the part-whole relation orders its universe, meaning that everything is a part of itself (reflexivity), that a part of a part of a whole is itself a part of that whole (transitivity), and that two distinct entities cannot each be a part of the other (antisymmetry). A variant of this axiomatization denies that anything is ever part of itself (irreflexive) while accepting transitivity, from which antisymmetry follows automatically. Standard university texts on logic and mathematics are silent about mereology, which has undoubtedly contributed to its obscurity. History[edit] A.N. In 1930, Henry Leonard completed a Harvard Ph.D. dissertation in philosophy, setting out a formal theory of the part-whole relation. Axioms and primitive notions[edit] The axioms are:

Developers Guide to Semantic Web Toolkits for different Programming Languages Abstract This guide collects links to Semantic Web toolkits for different programming languages and gives an overview about the features of each toolkit, the strength of the development effort and the toolkit's user community. Table of Contents This guide collects links to Semantic Web toolkits for different programming languages. which features are offered (APIs, query languages, storage, reasoning support), the strength of the development effort (number of developers involved, latest release), the activity level of the toolkit's user community (number of downloads, active mailing list). Our current evaluation results are found below. Request for Support We are trying to keep this guide up-to-date. If you know about a toolkit that we have missed, it would be nice if you could send us a link. All hints are highly appreciated. Alternative Toolkit Lists Other, alternative toolkit lists are found at This chapter lists all known toolkits ordered by programming language. 2.2 Haskell 2.9 Pike
