Axis

• CURIE: gmeow:Axis
• IRI: https://blackcatinformatics.ca/gmeow/Axis
• Category: class
• Defined by: gmeow:slices/places
• Box roles: TBox role (What is this?)

A coordinate axis or dimension of a reference frame (e.g. X, Y, Z, latitude, longitude, elevation, time).

Structure

Subclass of: gmeow:Entity, gufo:Object

Practical Pattern

Use gmeow:Axis as a specialized kind of gmeow:Entity, gufo:Object. Add statement metadata or a standpoint when the assertion needs provenance, confidence, or vantage.

Usage Advice

Use when

• Use for a coordinate axis or dimension of a reference frame (X, Y, Z, latitude, time, a joint angle).

Avoid when

• Avoid minting n separate axes for a finite-dimensional vector space — use one Axis with gmeow:hasCoordinateMatrix encoding the shape (Principle 12).

How to use

• Attach Axis instances to a frame via gmeow:hasAxis; for high-dimensional spaces carry the structure in a single axis matrix, not many individuals.

Examples

• ex:xAxis a gmeow:Axis; gmeow:hasCoordinateMatrix "[[1,0,0]]".
