Open Source Linux Semantic Web Software

Cube is the semantic layer for building data applications. It helps data engineers and application developers access data from modern data stores, organize it into consistent definitions, and deliver it to every application. Cube was designed to work with all SQL-enabled data sources, including cloud data warehouses like Snowflake or Google BigQuery, query engines like Presto or Amazon Athena, and application databases like Postgres. Cube has a built-in relational caching engine to provide sub-second latency and high concurrency for API requests.

This project is no longer actively maintained.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.

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.

Smart-M3 is a functional platform that provides a cross domain search extent for triple based information. Smart-M3 enables smart cross domain applications that rely on information level interoperability.

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

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.

This is a generic XML to RDF converter which uses XSLT transformations to convert any XML document into RDF format. The transformation uses an XSLT processor like xsltproc. The command line for the Bash shell is: xsltproc xml2rdf3.xsl document.xml > document.rdf Reference: Breitling, F. 2009: A standard transformation from XML to RDF via XSLT, Astronomical Notes, Vol 330 Issue 7, DOI: 10.1002/asna.200811233, http://onlinelibrary.wiley.com/doi/10.1002/asna.200811233/abstract http://adsabs.harvard.edu/abs/2009AN....330..755B https://arxiv.org/abs/0906.2291

This library facilitates a creation and management of OWL 2 ontology that describes a web service as defined in WSDL Version 2.0: RDF Mapping W3C specification. While the specification is based OWL 1.1 version, the library uses "The OWL API" which is OWL 2 based.

The Common Lisp Reasoner extends the Common Lisp Object System (CLOS) to incorporate a powerful rule language suitable for all kinds of reasoning tasks, vanilla XML and RDF/XML interfaces, and support for a variety of AI-related applications, such as scheduling, planning and diagnosis.

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.
