QuaaxTM is a PHP ISO/IEC 13250 Topic Maps engine which implements PHPTMAPI. This enables developers to work against a standardized API. QuaaxTM uses MySQL with InnoDB or MariaDB with XtraDB as storage engine and benefits from transaction support and referential integrity.

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.

RDBToOnto allows to automatically generate fine-tuned OWL ontologies from relational databases. A major feature of this full-fledged tool is the ability to produce structured ontologies with deeper hierarchies by exploiting both the database schema and the stored data. RDBToOnto can be exploited to produce RDF Linked Data. It can also be used to generate highly accurate RDB-to-RDF mapping rules (for D2RQ Server and Triplify).

GIN Server is a semantic middleware for easy data integration and automized analysis. The extendable architecture allows to plugin in data sources, analytics and event handling. This RDF Content Provider enables access to Semantic Web Content as an RDF file or SPAEQL endpoint.

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.

*** PROJECT NOT MAINTAINED ANYMORE *** RDFStats generates statistics for RDF datasets behind SPARQL-endpoints and within single RDF documents.

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).

ROO is an (OWL) ontology construction tool based on Protégé 4. ROO makes the ontology building process easier as it provides guidance about the steps involved and it allows to enter knowledge using an easy to learn controlled natural language.

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

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.

A library to allow query a SPARQL end-point in Python

SPARQL to Object Oriented eNgine allows users to expose their traditional data sources (RDBMS, OODBMS, XML, LDAP, ecc) as RDF data, through a SPARQL endpoint.

The DLP tool was ideated and developed by: Dr. Luca Mazzola, MsC. Patrick Kapahnke, and PD Dr. Matthias Klusch at the German Research Center for Artificial Intelligence DFKI GmbH (http://www.dfki.de ) in Saarbrücken, Germany.

The aim of this project is to provide a set of useful tools in semantic web stuff. It is part of the Semantic Web Group at LIFIA laboratory in Argentina.

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.

SAIM allows to interlink knowledge bases in the Semantic Web. It focuses on instance matching of very large knowledge bases available as SPARQL endpoints. SAIM uses machine learning techniques and is compatible with SILK.

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.

A simple tool for sketching out ontology structures, including OWL export. Developed at the University of Manchester as a third-year project.

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

Sofa is a CUDA-based reasoner

The definition of the metamodel for TRAK (defines allowed AD elements and relationships i.e. tuples/ triples for the TRAK viewpoints and views). TRAK is a general systems-thinkers'/system engineering enterprise architecture framework. It is simple, user-friendly, pragmatic and not limited to IT. 100% triple-centric and semantically-sound. Forms basis for RDF + OWL ontology description - see https://trakmetamodel.sourceforge.io/vocab/TRAK_metamodel.html. Each TRAK metamodel element now has its own web page - see https://trakmetamodel.sourceforge.io/metamodel/index.html

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.

This project is dedicated for semantic annotation of video and image files and development of a unified page ranking for them.

This Projects aims to create a server-client architecture to make annotation of web elements not only possible, but easy to use. The idea for this project has its roots within a practical software study for the module software Engeneering of the Unisversity of Leipzig, Germany. Under the given liscence we want for everyone interested in supporting or further development to do so. For usage and installation see our [Wiki].

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.
