Categorizing in an open tree


     Because the OMA tree structure is open for anything, it is a big
     challenge to bring your information to meaning. If you have to
     categorize an apple, a pie and a peach, you follow the structure
     of the tree. You extend this structure by setting up a new node for
     "Food" and put all three things in this node. If you insert a new
     information about a chair, a table and a lamp, you add the category
     "Furniture" on the appropriate level and throw these things in there.
     
     If you want to add information on bananas, pears and kiwis to
     the tree, it would make sense to set up a new category "Fruits",
     under the "Food" category and bring all fruits into this category.
     
     Everything you do, you do it on your subjective point of view and
     that reflects who you are. The OMA tree structure is a view of the
     cultural context of the makers. They have to sit down together and
     talk about their work to define their categories clearly, especially
     under the aspect of the people from "the outside".
