@alexntg Just checked about DAM
From Wikipedia: Digital asset management (DAM) consists of management tasks and decisions surrounding the ingestion, annotation, cataloguing, storage, retrieval and distribution of digital assets. Digital photographs, animations, videos and music exemplify the target areas of media asset management (a sub-category of DAM).[1]
Digital asset management systems (DAMS) include computer software and hardware systems that aid in the process of digital asset management.
The term "digital asset management" (DAM) also refers to the protocol for downloading, renaming, backing up, rating, grouping, archiving, optimizing, maintaining, thinning, and exporting files.
Since the requirement is to upload contents like videos, images, logo etc and manage them, I still think it comes under digital asset management and not document management. Plus as per resourcespace site, which I think best suits the requirement, also describes it.ResourceSpace open source digital asset management software is the simple, fast, & free way to organise your digital assets
