A method is disclosed that may include, in a creating phase: receiving an instruction to generate a virtual place-located anchor at a virtual location that is world-locked; receiving data items from a target data source; linking a subset of the data items to the virtual place-located anchor; and receiving a permission from a first user specifying a condition under which a second user may view one or more holograms of the subset of data items. In a viewing phase, first display data may be transmitted to cause a first display device to display the holograms to the first user at the virtual place-located anchor; and if the condition is satisfied, second display data may be transmitted to cause a second display device to display the holograms to the second user at the virtual place-located anchor.
