Abstract: Embodiments include systems and methods that enable enrichment and sharing of online content between users. These systems and methods provide mechanisms that allow users to author and overlay metadata as transparent containers on already existing data containers within models of the online content, as well as to create relational connections between people and objects across the web by communicating the overlaid online content. The metadata and relationships may be collected from user-authored input by overlaying virtual transparent screens over the online content. The virtual transparent screens enable the users to share the content by visually marking, or otherwise indicating, locations of interest on the content through the virtual transparent screens. The users may then author input related to the marked locations to be placed in the transparent containers associated with the marked location. The enriched content is then processed and rendered to other users through the transparent containers.
