FEATURE OBJECT ATTRIBUTES

Attribute: Logical connectives

Acronym: LOGCON Code: ?

Camel case: logicalConnectives

Attribute type: Enumeration

Definition:
Expresses whether all the constraints described by its co-attributes must be satisfied, or only one such constraint need be satisfied.

Attribute values:

1 logical conjunction

2 logical disjunction

Definitions:

logical conjunction

all the conditions described by the other attributes of the object, or sub-attributes of the same complex attribute, are true

logical disjunction

at least one of the conditions described by the other attributes of the object, or sub-attributes of the same complex attributes, is true

Remark:
* This atribute is intended to be used with co-attributes that encode limits on vessel dimensions, type of cargo, and other characteristics.
* The combination of constraints described by logicalConnective and its co-attributes defines a subset of vessels to which information described by a feature or information type instance applies (or does not apply, is required, recommended, etc.).
* The relationship between the vessel subset and the information is indicated by an association - see [[PERMIS|PermissionType]] and [[INCTYP|InclusionType]]).
* The two listed values of logicalConnective are two of the basic operations of Boolean logic. The third basic operation (''not'') is not used.

Example:
 applicabilty
 logicalConnectives=1
 vesselsMeasurements [vesselsCharacteristics=10/vesselsCharacteristicsValue=50.0/ComparisonOperator=1]
 vesselsMeasurements [vesselsCharacteristics=6/vesselsCharacteristicsValue=10.0/ComparisonOperator=1]

implies the limitation applies only when LOA > 50.0 and draught > 10.0

Distinction:

Nil

Justification: 

New attribute

Remarks: Add:
When bound to the object CHALIM, OPERAT can take only the values 3 or 4.

CHALIM/MAXLOA = 50.0, CHALIM/MAXDRF=10.0, CHALIM/OPERAT=3
