Domain:

crm:E55 Type

Range:

crm:E55 Type

Quantification:

0,n:0,n

Scope note:

This property allows an instance of E55 Type from a particular concept scheme or vocabulary to be declared as having an order relative to other instances of E55 Type in the same or other concept schemes, without necessarily having a specific value associated with either instance. This allows, for example, for an E55 Type instance representing the concept of "good" in a conservation report vocabulary to be greater than the E55 Type instance representing the concept of "average" in the same vocabulary. This property is transitive, and thus if "average" is greater than "poor", then "good" is also greater than "poor". In the domain of statistics, types that participate in this kind of relationship are called "Ordinal Variables"; as opposed to those without order which are called "Nominal Variables". This property allows for queries that select based on the relative position of participating E55 Types.

Examples:

In the condition survey of the manuscripts of the library of the Saint Catherine Monastery, the option ‘supple’ (E55) is conceptually greater than the option ‘stiff’ (E55). [These options are used for assessing parchment on page 2, section 2 of the survey form and within the context of the dry conditions of the Sinai desert where the Monastery is, ‘supple’ is considered better because it is less brittle] (Pickwoad, 2004)

In First Order Logic:

• O28(x,y) ⇒ E55(x)
• O28(x,y) ⇒ E55(y)
