The document discusses populating and browsing 3D collections. It defines a 3D collection as a digital archive containing multimedia materials and 3D artifacts enriched with semantic information. The workflow involves acquiring assets and metadata (population), accessing and exploring assets (browsing), and increasing associations within the semantic network (enriching). It provides examples of 3D collections with varying levels of metadata and discusses opportunities to leverage cloud computing, 3D on the web, and mobile devices.
