Attribute Model
Contents
Introduction
This page describes the Higgins concept of Attribute Model
Definition
- Defines the type(s) of its value(s) (e.g. "string" or "calendar-event")
- May define the minimum cardinality of this Attribute--the minimum number of values that are allowed (e.g. >=3 values)
- May define the maximum cardinality of this Attribute--the minimum number of values that are allowed (e.g. <=100 values)
Attribute Value Model (AVM) (e.g. directory string)
- May specialize:
- a base XML Schema type (e.g. String) for literal AVMs
- OR a complex AVM
- OR another AVM
- Defines a set of constraints on its value(s) including:
- Value must be one of {"red", "green", "blue"}
- Syntax constraints (e.g. regular expression)
- ranges (e.g. less than 5, more than 100)
- matching rules
