Logical classifications

A logical classification combines the results of other classifications using boolean logic.

Logical classifications reference existing classifications and evaluate their combined results to produce a single boolean outcome.

true
false

Logical classifications are automatically re-evaluated whenever any change occurs that could affect the result, including changes in referenced classifications, underlying data, or time-dependent conditions.

Evaluation model

Logical classifications evaluate patterns of boolean results produced by other classifications.

A logical classification evaluates to true if any configured row matches.

Properties

Name

Human-readable name used in the interface.

Names do not need to be unique.

API name

Identifier used internally and in API usage.

Rules:

• lowercase
• allowed characters: a–z, 0–9, _
• must be unique within the table

Table

The table where the classification is defined.

The classification is evaluated independently for each row of this table.

Referenced classifications

Logical classifications reference other classifications defined on the same table.

Supported reference types:

• value classifications
• relational classifications
• logical classifications

Logical classifications may reference other logical classifications, allowing nested logic structures.

Circular references are not allowed. The system prevents saving configurations that would introduce cyclic dependencies.

Configuration model

Logical classifications use a simplified truth-table model.

Each configuration row defines a required pattern of boolean values across the referenced classifications.

For each referenced classification, a row may specify:

true
false
ignore

Row evaluation

Within a configuration row:

• all specified conditions must match

Across configuration rows:

• if any row matches, the classification evaluates to true
• if no row matches, the classification evaluates to false

This model provides the equivalent of logical operators such as:

AND
OR
NOT

without requiring explicit operator syntax.

Modification

All logical classification properties can be modified after creation.

Deletion

Logical classifications can be deleted freely.
