At the beginning the main aim of the development of the "SDMX NSI Reference Infrastructure'' was to provide the countries with a non-invasive infrastructure that could "wrap" existing statistical dissemination/reporting architecture and make them SDMX compliant. Now that the "SDMX NSI Reference Infrastructure" is available and enough mature, the next step is to foster a community of developers from the National Statistical Institutes and other statistical Organizations with the main aim to encourage further developments based on that Infrastructure, so to provide to the SDMX community a set of software that can be re-used partially or as a whole, but that they can guarantee homogeneity and interoperability.

The ESSnet on SDMX phase I, which will finish at the end of March 2011, has already adapted some of its objective, in order to fit the aims, described above, of the "SDMX NSI Reference Infrastructure" produced by Eurostat. Two representative examples are documented in WP4 (Generalized SDMX Framework) and in WP7 (PC-Axis with SDMX-ML).

The ESSnet on SDMX phase II moves a step forward and besides continuing some of the work of a previous ESSnet on SDMX phase I (see WP2 and WP3), wants facilitate the rationalization of the current offer of the SDMX software in order to foster both a community of SDMX developers and users. In this context the SDMX NSI Reference Infrastructure, more than the ESSnet phase I, will have a central position in all the tasks.

Working packages

WP 1 - Project management

Assure the overall management of the Action, thus covering all the aspects related to an efficient management of the action and consequently of each WP, resources, schedules, issues and adequate implementation. The budget of this WP encloses four travels to Luxembourg for all partner countries, with the porpoise of the co-ordinator meeting.

WP 2 -  PC-Axis-SDMX ML integration Phase 2

The aim of the work package is to integrate PC-Axis with SDMX continuing the work started in the first ESSnet on SDMX. The results could be provided for the PC-Axis community.

D - 2.1 Documentation. Documents to be delivered is use cases with different type of materials. The experiences at Statistics Sweden from the present routines for delivery of statistics to International organizations is that with de different type of material and different key families there is a lot of activities to find how to prepare the materials. We foresee the same type work with the adaption of different material with the mapping to the DSD:s in the SDMX platform. The documentation is are supposed to be used in the workshops planned for other NSI:s also as a part of the Phase 2 of the project.

D - 2.2 Workshops. We plan two workshops to be held for other NSI:s in the PC-Axis community where also other NSI can participate as observers. The purpose with the workshops is to transfer the methods and software for use of the same platform based on PC-axis and the Eurostat SDMX Reference Architecture achievements in Phase 1 and Phase 2.

D - 2.3 SDMX functionality integrated in the web-software

WP 3 - Support of SDMX application for micro data handling, within statistical business process at the NSI level

The work shall comprise the analysis of the relevant phases of the statistical business process, the need of metadata in these phases and how the SDMX standards could be used at NSI for supporting statistical microdata description and its exchange. The system will be developed as open one with the possibility to support an use of SDMX standard in the whole business process flow. The work shall result into outputs of methodological and technological nature with the pilot application to verify the SDMX use in the of micro-data description, its further processing and eventual dissemination. The version of SDMX used is conditioned by the fact, that the tools we will be using (Data Structure Wizard, Metadata editor, Mapping assistant) will be also v2.1 SDMX compliant..

D - 3.1 Design of system architecture and system functionality

WP 4 - Harmonization of the existing SDMX tools and software

This WP will take as input: (i) the deliverables of the ESSnet on SDMX phase I with particular attention at WP4 (Generalized SDMX Framework), (ii) others SDMX software currently used in NSIs and available as open source, (iii) dissemination database schemas not still handled by the "SDMX NSI Reference Infrastructure" (e.g statistical data warehouse based on OECD.STAT), (iv) the current available software and documentation of the "SDMX NSI Reference Infrastructure”. The work and the deliverables will take in account the version of SDMX in which tools have been developed.

D 4.1
(a) Production of a technical document on "where to improve the documentation of the current software modules and manuals"
(b) Production of a step-by-step tutorial on "how to enhance/improve the SDMX NSI Reference Infrastructure" with source code  examples.

D 4.2 - Production of a technical document with the appropriate use-case describing functionalities already existing in other SDMX software that can be integrated within the "SDMX NSI Reference Infrastructure"

D 4.3 - Production of a technical analysis on how to incorporate modules developed in the ESSnet phase I WP4 into the "SDMX NSI Reference Infrastructure": (a) EGR modules (b) Reference Metadata modules (c) SDMX Data Express

D 4.4 - Production of a technical document describing the characteristics of other statistical database not still covered in the current version of the "SDMX NSI Reference Infrastructure" that can be incorporated in it

D 4.5 - Production of a document contains the specification of a set of templates to be used for further developments of the "SDMX NSI Reference Infrastructure" by the community of developers

WP 5 - Capacity building actions and dissemination of the ESSnet results

This WP will take as input: (i) the available training documentation, the self-learning tutorials, and the SDMX User Guide; (ii) the programs of the current available SDMX Trainings provided by Eurostat directly or indirectly through ESTP; (iii) the presentations provided during the bilateral meetings between Eurostat and the MSs; (v) the SDMX workshops that took place in 2009 at UNECE (in Geneva) and at UNESWA (in Beirut). Those two workshops were based on the agenda suggested by the SDMX Secretariat and oriented to management, statistician an IT staff.

D 5.2 Questionnaire to be sent to countries and document with an analysis of the results
D 5.3 Workshop documentation: agenda, slides, workshop user guide
D 5.4 Handbook on SDMX.
D 5.5 Workshop on SDMX.
D 5.6 Dissemination of the ESSnet results through a web site
