The approved platform or platforms where an organisation stores and manages its official records: an EDRMS, configured SharePoint/M365, line-of-business systems, or physical storage. The test is whether it maintains trustworthiness and accessibility over time.
A recordkeeping system is the approved platform (or platforms) where official records are stored and managed: an EDRMS, configured SharePoint or M365, line-of-business systems, or physical storage. The real test is whether it maintains trustworthiness and accessibility over time.
It can, if it is configured and governed so records stay trustworthy and accessible over time. The platform matters less than whether it maintains capture, metadata, control, and accessibility.
IAR turns terms like this into working practice: assets classified against your disposal authority, stewarded by position, and ready to evidence.
