| − | This page describes the Higgins concept of [[Attribute Model]]
| |
| | | | |
| − | == Definition ==
| |
| − | * Defines the type(s) of the value(s) of an [[Attribute]] (e.g. "string" or "calendar-event")
| |
| − | * May define the minimum cardinality of an [[Attribute]]--the minimum number of values that are allowed (e.g. >=3 values)
| |
| − | * May define the maximum cardinality of an [[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
