First release of OpenCube Toolkit

EU consortium releases a range of open source software components allowing end-users to publish, visualize and process multidimensional data.

The EU co-funded consortium OpenCube, headed by the Centre for Research and Technology Hellas (CERTH), is presenting its first software deliverable: a range of open source software components that will help governments, organizations, companies and citizens to publish, visualize and analyze multidimensional data according to the RDF Data Cube Vocabulary standard. These components are now available online, both separately and bundled in the integrated OpenCube Toolkit.  

Open Cube Toolkit

The OpenCube Toolkit is the first comprehensive software solution for data analytics based on Linked Open Statistical Data (LOSD). As a set of free-to-use integrated open source components, the OpenCube Toolkit has been developed to be able to process multi-dimensional data represented as RDF (Resource Description Framework) and structured according to the RDF Data Cube Vocabulary. This way, the OpenCube initiative wants to make LOSD more accessible to publishers and users and enable an easier analysis of these data. 

By making these first components available online (, the OpenCube consortium hopes to stimulate an active developer community. In addition to this community site, a demo site ( has been developed which showcases the finalized software components. 

Some components have also been integrated into the commercial products Information Workbench and PublishMyData, respectively developed by the consortium’s partners fluid Operations AG (Walldorf, Germany) and SWIRRL IT LIMITED (Manchester, UK). 

Pilot projects

As a guideline for the further development of the OpenCube project, these first software deliverables are evaluated in four pilot projects, involving the UK Department for Communities and Local Government (DCLG), the Irish Central Statistics Office (CSO), the Research Unit of the Flemish Government (SVR), and the Global Macroeconomic Research Unit of a major Swiss bank.

OpenCube objectives

The ability to extract valuable information out of open statistical data is critical for governments, because it can increase government transparency and accountability, and help them shape their policies based on facts and trends. However, statistical open data are usually provided in formats that lack metadata facilities or can only be read by using expensive specialist software. Today’s users prefer to publish multi-dimensional data according to more open and semantically rich standards, such as the RDF Data Cube Vocabulary. To publish and process these LOSD data, free and user-friendly tools are required. This is where the OpenCube Toolkit comes in, as the first comprehensive software solution for data publishing and analytics based on LOSD. 

OpenCube consortium

Launched in November 2013, the OpenCube project is coordinated by the Centre for Research and Technology Hellas (CERTH) and supported by the National University of Ireland, Galway as an R&D partner. The OpenCube consortium also includes three commercial partners: fluid Operations AG (Walldorf, Germany), SWIRRL IT LIMITED (Manchester, UK) and ProXML BVBA (Keerbergen, Belgium). The project is part of the EU’s 7th Framework Programme for Research.
