Persistence is supported because the rooms exist even when no one is in them. Consequently, the document remains in the room for future visitors to see until some authorized user moves or deletes it. It also tracks information about who has edited a document and when, and allows each editor to summarize changes upon saving. Each room provides context for collaborations within it. Floors and rooms may be named as appropriate, and room descriptions can be provided to provide additional context for the room.
Users can navigate through the virtual building with the graphical map or with a textual command.
