Mennonite Archival Information Database (MAID)
The Mennonite Archival Information Database (MAID) is a Canadian consortium that migrated roughly 80,000 records and 13,000 scanned images out of three separate bespoke Microsoft Access databases into a shared AtoM instance. The central challenge was 'dirty data': decades of idiosyncratic cataloguing with inexact dates such as '[196?]' and no enforced hierarchy. PeaceWorks Technology wrote automated routines to clean and remap the flat Access tables to ISAD(G)-compliant AtoM import templates, and even built a custom e-commerce plugin for the platform. Documented in the journal Archivaria, it is a strong example of small religious-community archives pooling resources to modernise collectively on open source.
