11. Controlling WorldCat Virtual International Authority File WorldCat Identities

12. Controlling names in WorldCat Has been done semi-manually – Encourages review of all links For Identities we did this automatically – Research copy of WorldCat – Very aggressive matching How to move links to WorldCat?

13. Pretend you are a Connexion Client Program to: – Log in – Search for record – Verify heading hasnt changed – Insert authorized form – Add link – Do replace

14. Then just replace 26 million records Each update takes two transactions – Retrieve the record – Replace the record If it takes 2 seconds/update – 52,000,000 seconds – ~ 2 years

15. But, we can run multiple clients Connexion can handle 40+ of these clients – ~ 20 records/second Offline processing has limited capacity – Run 32 clients for 12 hours for 16 updates/second – ~700,000 overnight – Up to a million/day 3 million/week 2-3 months elapsed time
