I have just posted an article on my blog about a pilot project that will be testing the ICA-AtoM software for use in a provincial union list of archival descriptions here in British Columbia, Canada.

The article also contains some more current information about the status of the ICA-AtoM software development.
As well, on May 6-7, the first meeting of the ICA-AtoM Steering Committee will take place at the Dutch Archiefschool in Amsterdam, the Netherlands.
