Part Of

Part Of (basic relationship) Title of this Item 

part_of Name of this Item 

A relationship of this type between two items is hierarchical. This relationship states that the subject (left-hand side) of the relationship ("A" in the relationship "A is Part-Of B", and like "SoftwareTesting" in "SoftwareTesting is Part-Of ComputerSoftware" in a categorization of engineering disciplines) is assumed to be more specific/narrow than, and contained within, what corresponds to the object of the relationship ("B" and "ComputerSoftware"). When showing a graph of connections between items, the system will attempt to indicate 'Part-Of' relationships as primarily vertical, with the object-item drawn nearer "the root" of the graph and the subject-item toward "the leaves". 'Part Of' is most appropriate for showing relationships that would be indicated by complete inclusion when drawing a Ven Diagram. That is, if drawing a Ven Diagram of how categories relate to each other, the category corresponding to the subject item of this relationship would be drawn entirely within the category corresponding to the object item. In this way, it is more restrictive than the 'One Of' relationship, which indicates membership without implying complete overlap. 'Part Of' is the opposite of 'Contains'. Creating a relationship that states one category is 'Part Of' another is exactly the same as creating a 'Contains' relationship with the subject and object reversed, and the system will list the relationship between them using both relationship names. 'Part Of' is itself a child of 'Child Of'. (And 'Child Of' is the opposite of 'Parent Of', and finally 'Contains' is a child of 'Parent Of'.) Description of this Item
