16 | Figure 2 Classification sequence with process having priority over organism 4.5 Hierarchies in classification schemes |
17 | 4.6 Notation 4.6.1 Purposes a) to provide a systematic sequence that enables location of concepts within the scheme and documents classified by the scheme; b) to serve as an unambiguous label for the intended concept. |
18 | 4.6.2 General description Figure 3 From Figure 2, with a simple notation and modified chain index added Figure 4 Example of a classification (UDC) with a notation that uses numbers and symbols |
19 | 4.6.3 Hospitality 4.6.4 Expressiveness 4.6.5 Synthesis 4.7 Alphabetical indexes to classification schemes |
20 | 4.8 Presentation a) The structure and relationships should be made clear, by appropriate layout, node labels, indentation and typography. b) The meaning and scope of each concept should be made clear, by notes and cross-references where necessary and by making it easy to see its context, e.g. by displaying previous steps of the hierarchy at the top of each page. c) A full explanation of the principles on which the scheme is constructed should be provided, with guidance on its application and the use of any provisions for synthesis of compound classes. d) A full index to the schedules should be provided, with guidance on the creation of index entries when the scheme is used to create a catalogue, including both enumerated and synthesized classes. 4.9 Management aspects of classification schemes |

24 | a) the relevant category label at the appropriate level of specificity only, for example, medical training; b) a unique identifier. Figure 5 Example of monohierarchical taxonomy, allowing repetition of category labels with differing scopes 1) the complete hierarchical string leading down to the class label at the right level of specificity, for example, Health/funding; 2) a unique identifier. 6.2.3 Taxonomies without vocabulary control 6.3 Choice of category labels |

27 | 6.6 Notation a) to sort the categories into the correct sequence and determine the appropriate typographical style and indentation level; and/or b) to provide a unique identifier for each category (see also 4.6). 6.7 Hierarchical structure 6.7.1 General |
28 | 6.7.2 Monohierarchy versus polyhierarchy Figure 6 Fragments of a polyhierarchical taxonomy |
29 | a) With a polyhierarchical structure it is important for users to recognize that the category with more than one parent has the … b) In a polyhierarchical taxonomy, if a category such as medical training has subcategories, the complete array of subcategories… c) Polyhierarchy has the advantage of providing more than one hierarchical route to a given topic, and hence supporting alternat… d) Monohierarchy has the advantage of providing implicit disambiguation for multi-meaning terms such as operations, but it is no… 6.7.3 Cross-references between categories |

35 | 7.3 New schemes a) As strings starting with the most specific concept, followed by other concepts which show its context, similar to the index strings shown on the right-hand side of Figure 3. Some strings may be abbreviated to omit obvious hierarchical steps. b) As strings in the reverse order, each starting with the more general concepts, followed by other more specific concepts. Omit… |
