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This project is no longer actively maintained.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 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.

OWL2XMI is a java project to facilitate the creation of classes UML diagrams. It generates a XMI file from one ontology, this XMI file can be imported using UML tools such as: StarUML, ArgoUML, among others. There are available online version, Visit Proj

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

OntoComP is a Protégé 4 plug-in for completing OWL ontologies. It enables the user to check whether an OWL ontology contains "all relevant information" about the application domain, and extends the ontology appropriately if this is not the case. It achieves this by asking the user questions of the form "are instances of classes C1 and C2 also instances of class C3?". If the user confirms such a question, then a new axiom of the application domain that does not follow from the ontology has been discovered, and it is added to the ontology. If the user rejects it, the user has to give a counterexample to this question, i.e., an individual that is an instance of C1, C2 and not C3. When all such questions (about some initially given classes) have been answered, the ontology is complete with respect to the application domain.

AnnoCultor: porting cultural repositories to the Semantic Web.

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.

DB2RDF is a a software tool that will convert data from relational data model to semantic data model (in the form of RDF and RDFS). A SPARQL endpoint for querying the converted data. For querying the semantic data, SPARQL query language is used.

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.

DynamiCoS is a framework to support user-centric service composition. It uses semantic web techniques to describe and discover services, which then are used in compositions that aim at satisfying user objectives. The current version is still an alpha version. Further developments are to be released soon.

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

Glue 2 is a Semantic Web Service discovery engine fully compatible with the WSMO meta-model and the WSML language that aims at solving polarization problems by using mediators.

HBaseTableManager lets you create HBaseTables from RDF be it in a File or remotely available via HTTP. An example HTable.rdf is included and also available via http://turnguard.com/hbase/util/HTable.rdf for testing.

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

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.

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 :(

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).

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

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

An extension of Sesame (http://www.openrdf.org) implementing Labeled RDF/S semantics. Statements can have a label, stored using Sesame "context". Labels can be partially ordered; a reasoner allowing to reason with labels is thus provided.

*** IMPORTANT NOTICE *** The source code of the earliest version of LODE is now available at http://www.github.com/essepuntato/LODE Even if the SourceForge repository is still active, it concerns old versions of the tool and it is not maintained anymore. *** SERVICE DESCRIPTION *** LODE is a service that extracts axioms and annotations from an OWL ontology, and renders them as ordered lists, together with their textual definitions, in a human-readable HTML page designed for browsing and navigation by means of embedded links.

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.

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

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.
