The problem with trees Many systems are organized hierarchically. The CERNDOC documentation system is an example, as is the Unix file system, and the VMS/HELP system. A tree has the practical advantage of giving every node a unique name. However, it does not allow the system to model the real world. For example, in a hierarchical HELP system such as VMS/HELP, one often gets to a lead on a tree such as: HELP COMPILER SOURCE_FORMAT PRAGMAS DEFAULTS only to find a reference to another leaf: Please see HELP COMPILER COMMAND OPTIONS DEFAULTS PRAGMAS and it is necessary to leave the system and re-enter it. What was needed was a link from one node to another, because in this case the information was not naturally organized into a tree.

Tanikawa House A Building socks-studio.com Show image 0 Show image 1 Show image 2 Photos of the Tanikawa House, designed by architect Kazuo Shinohara. Built in 1974, this summer house materializes the act of covering a piece of earth, making it an inhabitation only by means of a roof protecting the dirt soil of the ground. The house lies on a slope in a middle of a wood and grows through an exposed timber frame structure which supports a large pitched roof. Under the roof, a minimal section of the house located on a side hosts some specific living functions concentrated on two floors: a bathroom, a kitchen, a bedroom and a staircase. This section lies in parallel to the main “earth room” (or “summer room”) and overlooks it. minimalism
