Open Source Java Semantic Web Software

This project is no longer actively maintained. It is succeeded by the Eclipse RDF4J project, which can be found at GitHub and at http://www.rdf4j.org/. Sesame is a de-facto standard framework for processing RDF data. This includes parsing, scalable storage, reasoning and full SPARQL 1.1 query/update support. Sesame offers a fully modular toolkit and an easy-to-use Java API that can be connected to all leading RDF storage solutions.

S-FENG stands for Semantic-FEderation Next Generation. S-FENG represents the solution for managing federation of registries with its related aspects: affiliation, promotion, semantic publication and discovery, according to UDDI 3.0.2 specifications.

SmartSlog (Smart Space Ontology) is a software/application development kit (SDK or ADK) for programming Smart-M3 agents (Knowledge Processors, KPs) that consume/produce smart space content according with its high-level ontological representation. SmartSlog applies the code generation approach: given an OWL ontology description, the ontology programming library is produced. The latter provides API to access the smart space via a Smart-M3 Semantic Information Broker (SIB) and data structures and functions to represent and maintain locally in KP code all ontology classes, relations, properties, and individuals. Since 2012 the project is supported by grant KA179 of Karelia ENPI programme, http://kareliaenpi.eu/ More information about project: http://oss.fruct.org/wiki/SmartSlog Smart-M3 on Wikipedia: http://en.wikipedia.org/wiki/Smart-M3

A project designed to create a standard mapping of RDF to Java.

This Java tool converts your RDF files from any RDF format to any other format. It is based on the openRDF.org Sesame project and is wrapped into one single jar file for easy usage.

MRCube is a graphical editing tool of RDF-based contents developed for managing a relationship between RDF and RDFS contents.

This project is a reasoner for the description logic EL+. It computes the concept subsumption hierarchy. It is an OWL 2 EL reasoner.

Conversor de ficheros en un formato de etiquetado origen a un formato de etiquetado destino: el parser que permite convertir ficheros de un formato a otro, está herramienta fue creada por la necesidad de convertir formatos en fichero RDF:DC a formato OWL para poder ser utilizado en Protègè. Posee un sistema de configuración de etiquetas origen y etiquetas destino, siendo posible la conversión de múltiples formatos diferentes. El programa está realizado en lenguaje JAVA.

A lightweight IDE for Artificial Intelligence. Started as GUI for the Euler reasoning engine. The sources can be N3, RDF, OWL, UML, eCore, plain XML or XSD, files or URL's. Wraps Drools (or CWM, FuXi) as N3 rules engines. Model based app. generation.

Network software for annotation and quality control of distributed data. Supported by NSF: DBI 0646266 and NSF: DBI 0960535. http://wiki.filteredpush.org

KADMOS provides a lightweight API for alignment of OWL 2 ontologies. It is based on the OWL API v3.

The “RDB2RDF Mapper” is a Java based software desktop application which allows a user to create a mapping file between a relational database and an RDFS/OWL ontology via a graphical user interface. This project is ANDS-funded.

RuDolFWS (a.k.a. RDFWS) is a web service that lets you add, modify, remove and manage ontologies in a remote Sesame repository server.

SAWA calculates a semantic similarity coefficient between two sentences. Coefficient is expressed between "0" and "1", where: 0 means there is not semantic similarity among them; 1 vice versa.

This project was designed for a reserach conducted in the area of mobile science inqiury using ontologies. This mobile web application 'ThinknLearn' uses ontology-based scaffolding to implement NCEA level 1science standard curriculum example as an experimental context. In this application, ontologies are designed using Protege 4.0 while Jena API and Pellet reasoner are used in the technical architecture of this application for extracting relevant information according to the requirements.

Webtracks’ objective is to develop an approach and mechanism for constructing and propagating structured information to describe the linkage between distributed research objects in the context of academic activities.

Spreadsheet-to-RDF wrapper capable of transforming spreadsheets to arbitrary RDF graphs; supports mapping language with powerful formula expressions as you know from Excel, local/remote Excel/ODF/CSV, SPARQL service - source available at https://github.com/theandyl/xlwrap

The aim of ALIVE is to develop new approaches to the engineering of flexible, adaptable distributed service-oriented systems based on the adaptation of social coordination and organisation mechanisms.

HERAKLES is a reasoning broker framework for OWL (Web Ontology Language) reasoning systems.

MACOW is a formal and scalable mandatory access implementation suitable on open worlds such as the provided on Semantic Web, Autonomic Computing and Coaltions and Federations scenarios. It is able to access control on distributed systems.

NG4J - 'Named Graphs API for Jena' is an extension to the Jena Semantic Web framework for parsing, manipulating and serializing sets of Named Graphs. For details about Named Graphs see http://www.w3.org/2004/03/trix/

RDFConvert is a simple command-line tool for converting RDF file betweeen different syntax formats. It is based on the OpenRDF Rio parser toolkit, and currently supports RDF/XML, Trig, Trix, Turtle, N3, N-Triples, RDF/JSON, JSON-LD, Sesame Binary RDF and N-Quads.

SemaRule Navigator is an Integrated Suite of Open-Source and Free-License Software, placing Semantic and Text Analysis Technologies in the toolbox of Researchers, Students, and Enterprises.

Some scenarios for neuroinformatics experiments are saved in standard XML document. This program should be able to parse almost any scenario so far to make a full-valuable RDF file, where every pieces of scenario has their own URI. This project is from University of West Bohemia in Czech republic, required to Fundamentals of Software Engineering (KIV/ZSWI).

Metadata.net is a collection of website components and tools for creating and using metadata produced by the eResearch Group at ITEE, University of Queensland.
