After using the Maple Ridge db as the case study for the article work, I've now done a final pass through all the results from the algorithm and generated SQL commands which have been run to add ethnicity for owners. These are the steps:

• Check all name lists manually. There were a couple of Indian names which were not picked up by the Lauderdale and Kestenbaum list process. Researched those, and a couple of other oddities.
• Generated SQL statements from the name lists. These are in three files in svn for the record.
• Copied live to dev db, and backed up live db.
• Uncommented the ethnicity field in the local_classes.php file in both databases and tested that the field is available.
• Ran SQL on dev db and tested results.
• Ran SQL on live db and tested results.
• Made a second backup of the live db.
