The working group proposes that three basic rule-types cover the majority of the complex relationships between names, events, interventions, and vocabulary items. The three types (act, biography, relationship) are defined according to the following form, called the RULE-

STRUCTURE:

i. Rule-Type Name - indicates the fundamental nature of the rule, such as the type of event it describes

ii. Rule-Type Definition

iii. List of Linked Entities

iv. Description of its Time-Structure - i.e. how many dates are needed to describe it

v. List of Vocab Types and Categories - which might qualify the linked entities' relationship.

vi. The Presence or Absence of a Notes Field for Additional Description

vii. Example Rules with (8.1) Explanation of the Rules

viii. Typical Narrative - with a table-like rendering of the narrative according to the appropriate rules. Note that the rendering of the data in the narrative more or less follows the structure suggested in the Standard Relational Model. However, how the data are actually represented in the database depends on the specific implementation chosen. See the sections 8.2. Abstract Fields and 9. SQL for other possible techniques.
