Corese stands for Conceptual Resource Search Engine. It is a Semantic Web Factory that enables the processing of RDFS, RDF, SPARQL and RDF Rules. KGRAM is a new generic SPARQL 1.1 interpreter that can process labelled graphs in addition to RDF.

Semantic Web Import
Semantic Web Import is a plugin allowing the Gephi platform to visualize the semantic RDF graphs. This plugin is made available under the CeCILL-B license. The last version of the plugin can be downnloaded through the Gephi platform. The source code can be found at https://gforge.inria.fr/scm/?group_id=3504. For more details, please contact us.
This platform brings raw structured data coming from various formats (relational databases, CSV, XML, ...) to semantic data interlinked. Datalift is funded by the French national research agency to develop a platform to publish and interlink datasets on the Web of data. It includes: format transformation, schema mapping, alignment, sparql end-point, access controle and licencing.
Sewese is built upon Corese engine and provides a set of primitives to build interfaces for queries, edition and navigation, and for the management of the transverse functions of a portal (presentation, internationalization, security, etc.). An ontology editor, a generic annotation editor and a basic rule editor are parts of the Sewese platform. The main purpose of Sewese is to integrate recurrent semantic web operations (e.g. perform a SPARQL Query, transform a result binding in a given view) in classic web technologies (e.g. JSP pages, servlet calls).

We provide GRDDL RDFa profiles for GRDDL source documents using the latest GRDDL RDFa transform. These profiles and the associated transformations are available as freeware and under the non viral open-source licence CeCILL-C. We also maintain a lightweight RDFa Parser in Java.
Web page extractor
We provide a simple web page text and metadata extractor API in Java as an JAR Archive (v1.2) with its Documentation and Sources. It requires Apache Lang library. It is available as freeware and under the non viral open-source licence CeCILL-C.
ECCO is a contextual and collaborative ontology editor. It allows people with different profile to work together on ontology creation. External NLP tools are integrated into the editor in order to allow users to extract significant terms from domain texts while a vocabulary is being created. Graphical tree views are provided to create a hierarchy from a vocabulary by drag'n'drop. The editor is available as freeware and under the non viral open-source licence CeCILL-C. For more details, please contact us.
