Metadata and Dissemination Presentation Transcript

  • 1. Metadata and Dissemination Katja Šnuderl
  • 2. Overview
    • Trends in data dissemination
    • How relevant and how useful are metadata?
    • PC-Axis as a structured metadata model
  • 3. Current trends
    • Shift from print to electronic dissemination
    • Communicate instead of disseminate
    • User friendliness
    • Layering
    • Content management systems (CMS)
    • Translation to English
  • 4. Paper vs. Web User selects data and designs tables Fixed table structure Contextual linking Quoting or re-writing Structured metadata Methodological explanations as free text No technical limitations Size of tables limited by the paper format No one reads more than a few lines Long texts are appropriate
  • 5. Paper AND Web
    • Archive
    • Print and take
    • No internet
    • Libraries
    • ! Coherence
    •  more workload for data producers, structured metadata help avoiding most of duplication
  • 6. Disseminate vs. communicate
    • To disseminate - ‘scatter about, spread (especially ideas) widely’
    • Pocket Oxford Dictionary
    • Disseminate = provide data to public, "take it or leave it"
    • Communicate = user-oriented approach, "get it and use it"
    • experiences + feedback
  • 7. User friendliness
    • Constrains of search engines  search keywords as metadata
    • Cognitive perception – learning by using  stable structure
    • Usability tests, customer satisfaction surveys
    • Personalization
  • 8. Layering
    • Content metadata
    • Methodological explanations
      • Content
      • Detail
      • Time
        • Common structure enables query linking
    • Crosscutting (key indicators)
    • User metadata
  • 9. Content Management System
    • Provides:
    • Structured templates
    • Controlled workflow
    • Re-usability
    • Needs to be efficient:
    • Process metadata
    • Content metadata
    • User training (process + content)
  • 10. Metadata shopping list
    • Classifications: common use, descriptions, special notes
    • Process: input source, output form, dates, persons (prepare, approve, contact)
    • Content: common descriptions, particularities
    • Restrictions: confidentiality rules, registered users access, download
    • Users: monitor hits, requests, comments, register users
  • 11. "Left outside" the system
    • News releases – comments on trends and current developments
    • Ad-hoc publications
    • Ad-hoc tables for advanced users
    • Try to document them within the metadata system
  • 12. Elements of a data release at SORS
    • Title (content + time period)
    • Summary
    • Commentary
    • Summary tables
    • Charts
    • Attachments
    • Links
      • Database list
      • Methodological explanations
      • Questionnaires
      • Release calendar
  • 13. What is PC-Axis ?
    • File format, a tool, de-facto standard
    • Started as a solution for census data presentation (Sweden)
    • Continued to develop and be used world-wide (~40 countries and organisations)
  • 14. Why do we use it?
    • Tailored for statistics
    • Helps us learn and identify some common standards in dissemination
    • Format itself is not so relevant as long as it is standardized at the corporate level
    • PC-Axis reference group  able to upgrade to any new dissemination standard
  • 15. PC-Axis basics
    • Files or databases
    • Data + structured metadata
  • 16. How does PC-Axis work ?
    • SQL database or files
    • Files serve better for less detailed tables, easier implementation, can be later migrated to database
    • SQL database needs common metadata and provides more functionalities for more detailed tables
    • Different input data formats
    • Re-usability of metadata
    • Different tools for data preparing and data visualisation
  • 17. What does it look like?
    • Let's see…
  • 18. Conclusions
    • Metadata influence quality of dissemination perception
    • Implementing a metadata information system helps optimizing process and structuring information for users
    • Users learn by doing, therefore it is important to respect common standards and trends
    • There are several output database formats on the market, PC-Axis is one of the options to use
