Open Statistical Data are very important for the EU
Users frequently want to blend & combine statistical data from multiple sources
But, these data usually resides in files and databases (data silos) that are hard to combine
3
Problem definition
Linked Data (LD) technology has the potential to enable combining and performinganalytics on top of disparate and previously isolated statistical data
However, relevant tools are few, scattered and un-tested under real-life conditions
Potential of using LD in statistical data analysis unexploited

The OpenCube project
OpenCube is a 2-year project funded by the EU within FP7
The project aims to develop and test processes and tools for managing statistical
linked open data.
The results will:
Facilitate data publishers to create linked data cubes from legacy formats
Empower data users to browse, visualise, link, expand and analyse data cubes.
Enable analysis not possible before (merging data cubes at a Web scale)

The OpenCube Project

OpenCube consortium
We propose a lifecycle for statistical LD
The lifecycle is divided into two phases: publish and reuse (orconsume)
The lifecycle prescribes the steps that raw data cubes* should go through in order to create value.
OpenCube also develops tools to support the whole lifecycle of linked statistical data.

* We assume statistical data is organized as data cubes, where each cellcontains a measure described based on a number of dimensions.
