1 ESSnet on SDMX Technical issues Workshop on ESSnets 31/5 1/6 2010, Stockholm

2 ESSnet on SDMX Technical issues Technical coordination Work packages Dissemination (wiki, web site)

3 ESSnet on SDMX Technical issues Objectives The main contents of the terms of reference: Implementation of SDMX at international and national level The further development of the SDMX standards used for data and metadata The further development of the SDMX Content- Oriented Guidelines The further development of the SDMX IT architecture and IT tools The increase of SDMX capacity and knowledge

4 ESSnet on SDMX Technical issues Objectives Broadening and strengthening a NSI standard SDMX framework (WP8); Making standard tools available to a more easy implementation of the standard SDMX in the processing and exchange of data and metadata files between national and international organizations (WP3, WP4, WP7); Improving the semantic harmonization of concepts and terminology supporting this standard (WP2); Disseminating related tools and documentation widely (WP9);

5 ESSnet on SDMX Technical issues Objectives Results have to be broadly reusable within the ESS Software tools developed on an Open Source basis and registered under European Union Public licence (EUPL); Ensures the following rights: Obtain the source code of the software from a free access repository; Use the software in any circumstances and for all usage Reproduce (copy, duplicate) the software Modify the original software The development of software should take care about: A modular design The use of a version control system Clear documentation Detailed information at

6 ESSnet on SDMX Technical issues Success factors Communication: all the members of the project shall communicate anything that might affect or contribute to the project; Good inter co-ordination between Work Packages, namely between WP s responsibles, in order to minimize the overlapping of work and to assure interoperability as always as needed; Strong involvement of all the participants and stakeholders; Allocation of the right people for each task ; Stick to the approved working plan, reporting as soon as possible any problem that could compromise it;

7 ESSnet on SDMX Technical issues Main achivements Involvement and increase of knowledge on NSI s about SDMX; Better inter co-ordination between Work Packages; Improvement of ROI ( Return On Information); A common framework to support integrated and interoperable solutions; Dramatic reduction of developments costs on each NSI, due to common tools and solutions;

8 ESSnet on SDMX Technical issues Technical coordination WP1 Management of the Action (PT) Work: Meetings: Monitoring the work in the different WP s, the coordination between WP s and the quality of the deliverables; To Identify problems and make proposals to overcome them; To Produce progress reports; Organizing coordination meetings; Reports: Kick-off meeting 16/10/ Eurostat and partner countries: Start the project, make a project review, establish the project governance, define roles and responsibilities, clarify the expectations of all parties; 2 nd coordination meeting 26/03/ progress evaluation Quarterly progress reports (January, April)

9 Technical coordination Difficulties: Sound knowledge of the state-of-the-art is needed In SDMX field there are too many software tools not yet broadly known and commonly accepted There are other standards for the same purpose Oportunities: Increase knowledge on SDMX An oportunity to implement SDMX in the Organization The possibility of influencing the way forward on the short and medium run

10 ESSnet on SDMX Technical issues Proposals A group of experts to assist the coordinator on technical evaluation of WP s would be desirable; A repository of specialized tech skills existing on each NSI, could resolve eventual gaps on a particular task, i.e. sharing knowledge not just information; Improvement on the current practise of reusing existing pieces of software already developed by someone in any project.

11 ESSnet on SDMX Technical issues Work Packages WP2 MCV Ontology (PT) Responsible: Statistics Portugal Goal: To create an ontology of statistical metadata based on Metadata Common Vocabulary (MCV) concepts Deliverables: 1 st version of the ontology - July nd version of the ontology November 2010 Final version of the ontology March 2011 Report describing the methodology used March 2011

12 ESSnet on SDMX Technical issues Work Packages WP2 MCV Ontology (PT)

13 ESSnet on SDMX Technical issues Work Packages WP2 MCV Ontology (PT) Terminological point of view Improve the quality of the definitions: More complete and accurate More clear More coherent among them

14 ESSnet on SDMX Technical issues Work Packages WP2 MCV Ontology (PT) Technological point of view Semantic Web Technologies(*) Web services software tools designed to support interoperable machine-to-machine interaction over a network Ontology Set of concepts, the relations among them and software for computing them Knowledge representation languages RDF, OWL (Web Ontology Language) Turn an ontology from a model of concepts into something that is computational Make inferences with the concepts in an ontology (*) The ideas and definitions in this slide were extracted from Open issues on the semantic web, Dan Gillman, Work session on statistical metadata (METIS), March 2010

15 ESSnet on SDMX Technical issues Work Packages WP3 SDMX Data Explorer (PT, IT, ES) Responsible : Statistics Portugal Participants: ISTAT, INE-SP Goal: To deliver a tool (using a generic SDMX class library) to visualize SDMX data files under different perspectives (html, CSV, Charts, SDMX format conversion) in a more user friendly way. Progress: Functional and technical specifications (03.D-1 finished); Analysis and design documentation (03.D-2 finished); User Interface prototype description(03.d-3 finished); The development of SDMX-ML Parser has been started; Source code available for partners in repository

16 ESSnet on SDMX Technical issues Work Packages WP3 SDMX Data Explorer (PT, IT, ES) Deliverables: Application package intended to explore statistical data using an SDMX data file and related DSD; Documentation associated with the tool: Functional and technical specifications Analysis and Design documentation User interface prototype User Manual Implementation report Application package: Web application, class library and web services
