INFORMATION PROCESSOR

In an information processor which stores and manages objects with attribute information added to the objects, an object is selected and attribute information of the object is stored in a storage medium. Then, in response to a command issued for copying the selected attribute information, the attribute information stored in the storage medium is added to another object. Thus, the same attribute information can be added to a different object easily. When the same attribute information is added to a plurality of objects, the attribute information selected are added to each of the objects at the same time and stored in a relation to each of the objects in the storage medium. Thus, the load for adding attribute information by a user is reduced largely. Beside a main dictionary which registers attribute information, a sub-dictionary registers data for identifying attribute information for a part of the attribute information registered in the main dictionary. Then, an attribute information can be selected easily in a dictionary even if the number of attribute information therein is large.
