Definition of Object-Oriented frbr

2.4. Presentation Conventions

All instances of E41 Appellation are presented within single quotation marks, whether they are used for themselves or just to refer to the things they name. Any punctuation mark that follows an instance of E41 Appellation is placed outside the single quotation marks, as it does not belong to the appellation itself.

Furthermore, all references to instances of E90 Symbolic Object in the form of a content model are presented within single quotation marks, such as ‘abc’. By content model we mean the symbol sequence the symbolic object consists of.

British spelling is used throughout the original English version of this document, except for occasional quotations and examples.

Double quotation marks are used to indicate an informal name or term. E.g.: The “lower member” consists of sandstone with minor shale.

2.5. Class & Property Hierarchies

Although they do not provide comprehensive definitions, compact monohierarchical presentations of the class and property IsA hierarchies have been found to significantly aid in the comprehension and navigation of FRBR_OO, and are therefore provided below.

The class hierarchy presented below has the following format:

• 
  Each line begins with a unique class identifier, consisting of a number preceded by the letter “F”.
  
• 
  A series of em dashes (“—”) follows the unique class identifier, indicating the hierarchical position of the class in the IsA hierarchy.
  
• 
  The English name of the class appears to the right of the em dashes.
  
• 
  The index is ordered by hierarchical level, in a “depth first” manner, from the smaller to the larger subhierarchies.
  
• 
  Classes that appear in more than one position in the class hierarchy as a result of multiple inheritance are shown in an italic typeface.
  

The property hierarchy presented below has the following format:

• 
  Each line begins with a unique property identifier, consisting of a number preceded by the letter “R”.
  
• 
  A series of em dashes (“—”) follows the unique property identifier, indicating the hierarchical position of the property in the IsA hierarchy.
  
• 
  The English name of the property appears to the right of the em dashes, followed by its inverse name in parentheses for reading in the range to domain direction.
  
• 
  The domain class for which the property is declared.
  
• 
  The range class that the property references.
  
• 
  The index is ordered by hierarchical level, in a “depth first” manner, from the smaller to the larger subhierarchies, and by property number between equal siblings.
  
• 
  Properties that appear in more than one position in the property hierarchy as a result of multiple inheritance are shown in an italic typeface.
