  3. Outline • Needs and challenges in statistical data and metadata management • Metadata and XML solutions • Selecting specifications • Need for tools • Open Data Foundation • Conclusions / Q&A

  4. Managing data and metadata is challenging! Academic Producers Users Librarians Sponsors Business Media/Press Policy Makers General Public Government • We are in charge of the data. We support our users but also need to protect our respondents! We have an information management problem • We want easy access to high quality and well documented data! • We need to collect the information from the producers, preserve it, and provide access to our users!

  5. What is Metadata? Labeled stuff Unlabeled stuff The bean example is taken from: A Manager’s Introduction to Adobe eXtensible Metadata Platform, http://www.adobe.com/products/xmp/pdfs/whitepaper.pdf • Common definition: Data about Data

  6. XML to the rescue! • XML is driving today’s web service oriented architecture of the Internet and Intranets • Using XML, we can capture, structure, transform, discover, exchange, query, edit and secure metadata and data • XML is platform & language independent and can be used by everyone • XML is both machine and human readable • XML is non-proprietary, public domain and many open tools exist • Domain specific standards are available!

  7. XML Technical Overview

  8. XML Solutions XML Specs Academic Producers Users Librarians Sponsors Media/Press Policy Makers Business General Public Government • Well documented data, here we come! • Great, I can provide public metadata! • Use our specifications and your will be happy! It will harmonize everything. • Now we can talk to each other!

  9. Let’s use XML, but…. XML Specs Open Data Foundation Producers Users Librarians ? • Which specifications should we adopt? • How do we do this? Where are the tools and guidelines?

  10. Open Data Foundation (ODaF) • US Based non-profit organization, established 2006 • Directors, advisors and managers from statistical and ICT communities • Project oriented • Mission • Focus on socio-economic data • Adoption of global metadata standards • Coordinated development of open-source tools • Capacity building • Improving data and metadata accessibility and overall quality • Operate at the global level

  11. Selecting XML specifications • A single specification is not enough! • XML specifications commonly focus on a specific area of knowledge and/or set of functionalities • Cannot answer the needs of all actors • XML mappings between specifications are possible • Information can be converted from one domain to another and be carried across communities • Which ones should we use? • Fit for purpose • Widely accepted and supported • Can be mapped to a cross-domain family

  12. A suggested set for socio-economic data • Statistical Data and Metadata Exchange (SDMX) • Macrodata, time series, indicators, registries • http://www.sdmx.org • Data Documentation Initiative (DDI) • Microdata (surveys, studies) • http://www.ddialliance.org • ISO 11179 • Semantic modeling, concepts, registries • http://metadata-standards.org/11179/ • ISO 19115 • Geography • http://www.isotc211.org/ • Dublin Core • Resources (documentation, images, multimedia) • http://www.dublincore.org

  13. The need for Tools XML Specs Open Data Foundation Producers Users Librarians • We set specifications and standards. Tools are not our mandate • We produce data not tools! We don’t have the expertise. • We preserve and disseminate data not software! We don’t have the expertise • We use data and software but we don’t build tools! We don’t have the expertise

  14. The need for Tools Open Data Foundation Mandated to develop tools Provide cross-domain expertise in ICT and statistics Provide umbrella for coordinated development Ensure inter-operability Outline harmonized architecture and environment Promote open source / maximize reusability Build global registries Resources/Fund raising Coordination / Networking …

  15. ODaF Vision • Promote and facilitate the production and use of “open data” • Public metadata, high quality, fully documented, respondent protected, easy to find, accessible in accordance to statistical principles and legislations • Foster a global harmonized framework • Facilitate the flow of data and metadata • Promotes dialog between all stakeholders Unlock the Data!

  16. Some ODaF Projects & Ideas • Guidelines for an harmonized architecture and development environment • Foster tools development • XML mappings • Facility to host development of open source projects (GForge) • Provide hosting services for agencies • Produce training and reference material • Technical support & capacity building • Bring people / agencies together • …

  17. ODaF partners • Statistical agencies / producers • Data Archives • Research Data Centers / Data enclaves • Academic & Research communities • Standard settings agencies & consortiums • Governmental organizations • International organizations • Open source community • Software developers • IT Vendors

This requires coordinated efforts and expertise from the various communities • OPEN DATA FOUNDATION • Provide cross-domain & IT expertise • Coordinate and support development • Knowledge sharing • Capacity Building • Provide global vision and guidance

  20. ODaF Projects / Activities • Advocacy • ODaF meetings (Europe, US) • Conferences (FedCasic, IASSIST, METIS, etc.) • Coordination / networking • DDI • DDI Foundation Tools Program (coordination, DExT, etc.) • Standards: DDI, SDMX, mappings • Research Data Centers / Data enclaves • National Opinion Research Center (NORC), Canada RDC, European initiatives • Establish standards based framework + investigate researcher metadata / collaborative spaces • Others • QuDExT, technical assistance (often semail) • Open to suggestions

  21. ODaF Challenges • The technology is available today • The right people are available today • The need and the will are there • The challenges are: • Bring together individuals and agencies • Develop of harmonized tools • Focus resources and funding • Develop awareness / understanding of technology • Manage change • Content management • Coordination & Guidance • Institutional commitment • Learn for the past for a better future • It’s not about data, it’s about people

  22. Summary • Managing data and metadata is challenging • Solutions exist to make it easier and provide better information to unlock the data • Adopt a set of specifications that answer your requirements and can connect across domains • DDI, SDMX, ISO 11179, Dublin Core, ISO 19115 • Promote the use and development of open tools, do not work in isolation, get the appropriate expertise • Open Data Foundation

  23. Meet the Icons... • THANK YOU!
