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.

Utilitarian craftwares become more beautiful the more they are used, and the more beautiful they become, the more they are used. Moreover, the heavens have ordained that these objects should attain an even greater beauty as they become worn by the handling of human hands. Putting Thought Into Things utility
Devoid of ambition Miscellaneous handicrafts are devoid of ambition. Their purpose is to serve the needs of the people, not to achieve renown. Just as construction workers who have built a wonderful highway don’t sign their work, neither do artisans append their names to their ware. From beginning to end, without exception, such handicrafts are made by nameless craftsmen. It is this lack of desire for personal recognition that produces their flawless beauty. Signing party ambition
The material finds the right object Rather than the craft object finding the most suitable material, it can be said that the material finds the right object. Folk crafts are invariably the product of a local environment. When a certain locality is rich in a certain raw material, that material gives rise to a certain craftware.

Nothing that nature does not seek Nature tells us the shape and pattern a material should assume, and nothing good can be achieved by ignoring its dictates. A good artisan seeks nothing that nature does not seek. natureform
