• f Statistical Processes

WHAT

• In the aftermath of the financial and economic crisis, NSOs

and international statistical organisations launched modernisation programmes

To address the gaps highlighted by the crisis To be ready to match the new evolving users'

requirements

WHY

• Get quick and ad hoc information, often across

domains, to face major events

• Decrease response burden by making data widely

available in a reliable way

• Implement ICT methods and tools to increase

efficiency

: A Coll

llaborati tive Approach

• Consequences for European Statistics:

Member States: holistic integration

• f information systems, throughout

the production chain

EU level: foster the implementation

• f collaborative networks

3

• ESS initiatives

Communication on the production

method of European statistics: a vision for the next decade”, COM (2009)404, August 2009 - Vision

ESS Vision 2020 – May 2014

: : Web eb-Semantic ic Da Data Warehouse Approach

• Project phase

Definition of the standards and the

architecture

Assessment of the degree of maturity of

existing national accounts systems with respect to the standards (FR, SE, EU)

Proof of concept and design of

architecture

• Experimentation phase

Translation of the production

processes in GSBPM phases and sub- processes

• Proof of concept
• Design of the architecture

Team work (national accountant, IT

specialist, web-semantic expert

• Three areas – RECEPTION – PRODUCTION - DISSEMINATION
• Integration LABORATORIES – PRODUCTION FACTORIES

: : … We Can Make It Compact …

• Symmetric RECEPTION /

DISSEMINATION

• One Entry Point Monitoring the

Flows

• Optimization of the Flows with the

Datawarehouse

Similarities in

management of formats in LOADERS

Similarities of rules

in the CHECKERS

A Comprehensive Architecture

• Security Center

Access rights controller

• Metadata Handler

Implementation of SDMX Local knowledge of the Metadata

• Statistics Center

Toolboxes and elementary processes I.e. Seasonal Adjustments, Benchmarking, Temporal

Disaggregation, Chain Linking, …

• Scheduler

Entry Point, i.e. the gateway to the Cloud Coordination of all component Synchronization of requests

Usin

sing Se Semantic WEB Techniques

• How to use at best the growing volumes of

metadata?

• How to understand heterogeneous

information from different sources?

… through integration of the Information

and not only the Data

Dealing with semi-structured information

• There is a semantic heterogeneity in

information

• What is needed to solve?

Integrated Conceptual Schema Mappings Wrappers

• Techniques: Semantic WEB Rules Language
