10. NOTES  When a method of measurement or definition or an attribute or concept changes, the old series is terminated, and a new series with a new series identifier is begun. (CANSIM – the many faces, UT/DLS)  When SIC 1980 was changed to NAICS 1997 series were terminated and new ones begun. This explains the limited time line of the NAICS series

14. NOTES – Searching/ Results  CHASS - get listing of series unless search by Table number  Stat Can - get listing of Tables unless search by Series number  Therefore difficult to compare retrieval  PETS – CHASS got 60 series (82 with carPETS)  PETS – Stat Can got 5 tables – did not include carpets  Important to check “Match full keyword” in CHASS

18. NOTES Notes from Chris Leowski’s presentation in 2002:  CANSIM II: vector numbers not recycled when a series terminated. In CANSIM I they were.  No frequency conversion in the CHASS CANSIM II, this is not a CHASS priority.  Badly need a way of pointing users to series that replace terminated series and vice versa.

22. Choosing which to use  Currency – Daily vs. weekly vs. yearly  Ease of searching – pick lists in Stat. Can. helpful  Sophistication of user – list of series can make finding data difficult with CHASS interface  Frequently used series are fast – in CHASS  Could use Stat Can interface to find series # and then go to CHASS to get most recent data  Output required – CHASS has more formats for statistical packages  Data manipulation required  Data visualisation required
