AtoM (Access to Memories) is an archival tool: an application that you use to manage the records that you find in archives such as the National Archives of Canada.
Normally you will want to install AtoM in a big server which can handle thousands of records but very small installations or for purely demonstration purposes, the installation on Raspberry Pi can be useful.
For me, the advantage of this hardware is it size and power comsumption. It has the advantage over a virtual machine that in can be left running all the time. In addition, using a VM is not feasible for everybody due to the hardware requirements.
The AtoM instructions advice to install mySQL 5.7. This did not work in my Raspberry Pi. When I tried to install mySQL, the Raspberry Pi OS reccommended installing mariadb-server-10.3, which is mentioned in the AtoM documentation as a possible akternative database.
The screen should show some information about the package you are about to install and ask for confirmation. Press “y”.
