An EDMS should allow storing and managing documents in multiple formats, including text, audio, video, and image files. It should have an advanced search engine to scan and retrieve documents regardless of the format, and should allow tagging with keywords for improving searchability.
Security is another important feature that restricts access only based on permissions. Collaborations across teams based anywhere are also a key feature of a good EDMS.
Audit Trail to trace changes, by whom, and when is an essential feature for both security and compliance.
