  1. An overview of selected DLI projects Marie-Claire Lauzon, Statistics Canada DLI Atlantic Training Acadia University April 24, 2008

  2. Objective • To provide an overview of some the projects the DLI unit has been working on in 2007-2008 • The DLI Survival Guide • The new and improved DLI collection interface • A faster search tool for the DLI listserv • DDI – Data Documentation Initiative and Nesstar

  3. The DLI Survival Guide – A bit of history • Based on: • The “Brian McNally First Aid CD-ROM” produced by Elizabeth Hamilton and her colleagues at the University of New Brunswick (UNB) - A quick reference guide for librarians that dedicate a short amount of time to data services • The 1997 training binder for new data librarians developed by the DLI unit

  4. The DLI Survival Guide – A bit of history • These resources were expanded through the efforts of Jane Fry, Carleton University, and the DLI unit at Statistics Canada • Chuck Humphrey, University of Alberta and Nancy Lemay, University of Ottawa, also contributed to the Guide

  5. DLI Survival Guide – National Training Day Demo • Draft version of the Guide presented during the DLI National Training Day (May 2007) • DLI unit received more than 100 suggestions from the DLI community • Incorporated these suggestions and translated the Guide • Released an updated, password protected, version

  6. DLI Survival Guide – Recent developments • Last month, the Centre of Expertise on Accessibility reviewed the guide and provided accessibility related recommendations • Their recommendations led us to re-write and re-code certain sections of the Guide • Replaced menu on right side with links at the top • Removed any instances of “click here” • Re-wrote expressions like “Position your mouse over the link below" (not everyone uses a mouse)

  7. DLI Survival Guide – Next Steps • Currently testing search feature with search specialists from our Dissemination Division • This week, the Guide is undergoing TASS (Testing and Support Services Unit) testing • Examine how the Guide works in different browsers • Identify any broken links • Provide usability recommendations • We will then implement the usability recommendations and release the Guide

  8. The new DLI collection interface • Goal: Facilitate access to DLI data and metadata • Being developed by IT specialists in the Dissemination Division • Jackie Godfrey is our DLI lead on the project • Will allow users to both browse and search the DLI collection • Will pull information from IMDB and Online Catalogue • Will eventually completely replace our static DLI collections pages

  9. The new DLI collection interface • Interface is based on the Statistics Canada Analytical Studies module • Users can search the Online Catalogue for DLI products by keyword • They can also browse the IMDB for DLI related surveys and related products • By Subject • By Date • By Survey

  10. Let’s have a look at the prototype… • http://www.statcan.ca/dli/english/dli?&dfold=0&currpg=1&sfold=0&survfold=0

  11. DLI Collection Interface Prototype • Next Steps • Continue to develop searching and browsing functionality, the interface design • Perform usability testing • Launch the interface and use it with the DLI static pages • Develop a fully independent interface

  12. The new dlilist search tool • Prototype based on open source application • A faster alternative to the existing listserv search tool • Available under “Alternate Search” on the dlilist

  13. The new dlilist search tool • Supports Boolean • AND, OR, NOT • Must be capitalized • Use “ ” to search as phrase • Use * to truncate

  14. Search results compared • Prototype faster • Primary tool shows search terms in bold in results • Primary tool shows total # of documents searched and # found

  15. dlilist search tool - next steps • Request input from the DLI community • Complete the prototype’s development • Functionality • Bold search terms in results list • Display # of documents searched and retrieved • Show author’s name • Search within results • Develop the interface • Test • Launch

  16. DDI – Data Documentation Initiative • DDI – Data Documentation Initiative • An international XML-based metadata tagging system for social science data • Allows for detailed and structured information searches across repositories or data collections tagged using DDI specifications

  17. DDI – Data Documentation Initiative • Statistics Canada working on DDI project since April 2007 • Other groups working on DDI: • ODESI (Ontario Data Extraction System Infrastructure) – a jointly funded project between the Ontario Council of University Libraries (OCUL) and OntarioBuys • Statistics Canada Research Data Centres (RDCs) will be coding Statistics Canada master files in DDI format • DDI specialist in DLI unit is Linda Harding-Devries

  18. DDI Best Practices Document • DLI unit has worked with: • Dr Michelle Edwards (Guelph University) • Jane Fry (Carleton University) • Irene Wong (University of Alberta) • Special Surveys Division at Statistics Canada • Developed the Statistics Canada best practices document for coding Statistics Canada files in DDI format • Goal: Ensure consistency in marking up surveys • Also working with other Divisions within StatCan on DDI related projects • Provides training to Statistics Canada Divisions on tagging DDI files

  19. Statistics Canada files in DDI • The following StatCan data files have been coded in DDI and are available through the DLI Nesstar site: • Canadian Tobacco Use Monitoring Survey (CTUMS), 2000-2007 • 1996 Census of Population (Households and Housing, Families and Individuals Files) • Public Service Employee Opinion Survey (PSES), 2002 and 2005 • Residential Telephone Service Survey (RTSS), 2004 (May and December), 2005 and 2006 • Youth Smoking Survey (YSS), 2002 • We will be adding these files next week: • Canadian Survey of Giving, Volunteering and Participating, 2004 • Employment Insurance Coverage Survey, 2000 to 2006

  20. The Statistics Canada Nesstar site • The DLI Nesstar site will be the official repository for StatCan data files in DDI compliant format • a virtual data library • users can search, browse, download and manipulate Statistics Canada data files to create their own tables • Files will be available in both French and English • DLI contacts can access DLI data with a user name and password • The metadata will be available to all. Clients will be able to perform variable level searches to locate data files • Next files to be tagged are Census of Population, Public Service Employee Opinion Survey (PSES), Residential Telephone Service Survey (RTSS), Youth Smoking Survey (YSS) files • Statistics Canada Nesstar site: www62.statcan.ca
