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This project is no longer actively maintained.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.

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

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

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.

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

TurtleScript is a semantic web project to demonstrate the utility of including the Turtle RDF serialization in HTML files as a form of metadata. It is intended as proposed alternative or supplement to microformats and RDFa.

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

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.

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

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.

Our aim is to enable Web applications to consume linked data from the Web. With SQUIN (Semantic Web Query Interface) we will provide a Web data query service as an addition to the LAMP technology stack. This service executes queries over the whole We

DODDLE-OWL is a domain ontology development tool for the Semantic Web. DODDLE-OWL makes reuse of existing ontologies and supports the semi-automatic construction of taxonomic and other relationships in domain ontologies from documents.

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).

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

The tRDF framework provides tools to deal with the trustworthiness of RDF data.

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.

Porting of the SmartM3 Triple Space's KP on JavaScript. Due to limitations on JS connectivity a "WebSocket to TCP" relay has been developed in order to enable JavaScript KP to communicato with a SmartM3 SIB. Relay is based on jWebSocketServer. User manual currently only in italian :(

MapPSO is a tool for Ontology Alignment, which uses Discrete Particle Swarm Optimisation. A particle swarm is used to search for the optimal alignment. The algorithm is massively parallel and adapts naturally on parallel architectures.

Arastreju is a Java based engine for ontology based information management.

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

A Java library which reads an OWL resource, e.g. an OWL file, and offers methods to get the contained information. For that is has methods to get all OWL classes together with their subclasses and their data types (i.e. their data properties), all relations of these OWL classes (i.e. all object properties), all OWL individuals together with their classes and their data values (i.e. their positive data property assertions) and all relations of these OWL individuals (i.e. all their positive object property assertions).

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/

A set of java api to manipulate a vcard file represented in RDF/XML according to W3C specification (http://www.w3.org/TR/vcard-rdf).
