  1. The Common Object RegistryKeeping www.statcan.ca visitors in context Paula Fedeski-Koundakjian Internet Content Manager Dissemination Division, Statistics Canada paula.fedeski-koundakjian@statcan.ca

  2. The holdings We have survey metadata for more than 650 surveys http://www.statcan.ca/english/sdds/indexa.htm We have more than 7,500 documents officially releasing survey data and publications http://www.statcan.ca/english/dai-quo/

  3. More holdings We have some 10,000 publications, products and services in the online catalogue. http://www.statcan.ca/english/search/ips.htm In CANSIM, we have nearly 2000 detailed tables containing over 18 million series. http://cansim2.statcan.ca/cgi-win/CNSMCGI.EXE

  4. And more holdings And finally, in Canadian Statistics, we have more than 400 summary tables, most of which are created automatically from CANSIM tables. http://www.statcan.ca/english/Pgdb/

  5. The challenge When visitors find an item in one data holding, they want to see that item in the context of the others.

  6. The problem It is impossible to create handmade links among related items because of • the size of our holdings, magnified by duplications; • the huge maintenance task; and • the inevitability of error.

  7. The solution

  8. What does COR do?

  9. The Daily

  10. CANSIM

  11. Canadian Statistics

  12. Canadian Statistics

  13. The online catalogue

  14. The Daily by subject

  15. Coming soon… COR links in a redesigned survey metadata interface.

  16. Statistics by Subject: A new website module providing maintenance-free, fully automated access to all the objects in COR by subject (theme and sub-theme).

  17. Automated, maintenance-free links inside HTML publications.

  18. How does COR work?

  19. COR stores only six objects • Themes (and sub-themes) • Surveys • Items in the online catalogue • CANSIM tables • Canadian Statistics tables • Daily releases

  20. COR tracks only two things • Object descriptions (ID, type, and English and French labels) • Relationships (the objects that are related to this one)

  21. Type of object Object’s ID number Object’s label OBJECT’S DESCRIPTION OBJECT’S RELATIONSHIPS WITH OTHER OBJECTS

  22. Holdings teams maintain it The team responsible for each data holding maintains • its own objects in COR • the relationships it “owns” in COR

  23. Advantages The holdings no longer contain • external objects, or • hyperlinks to external objects. • Work and responsibility are distributed among many people.

  24. Themes Sub-themes Surveys Daily releases CANSIM tables Canadian Statistics tables Items in the online catalogue Relationships within COR

  25. Difficulties • CORification of data holdings is not simple or quick. • The taxonomy must be applied strategically and uniformly across holdings. • Imperfections are inevitable. • Registration of Daily releases in COR could not be done wholesale or retroactively. • Data must be in CANSIM for Canadian Statistics tables to show. • COR does not capture all data holdings (data not available in CANSIM, data in other databases, e.g., Census of Population and Agriculture data).

  26. What’s next • Launch Statistics by Subject in the spring. • Create new interfaces for COR output which are harmonized and have high usability. • Design databases that make COR redundant…
