Orientation

• CURIE: gmeow:Orientation

• Category: class
• Defined by: gmeow:slices/places
• Box roles: TBox role (What is this?)

The rotational component of a pose, expressed as co-equal optional facets: quaternion (x, y, z, w), Euler angles (yaw, pitch, roll plus order), or compass angles (heading, bearing). No single representation is privileged; multiple representations may coexist for the same pose. Aligns by reference to IEEE 1872-2015 pos:OrientationMeasure.

Structure

Subclass of: gmeow:Entity, gufo:Object

Practical Pattern

Use gmeow:Orientation 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 the rotational component of a pose, in any of the co-equal facets — quaternion, Euler angles, or compass heading/bearing.

Avoid when

• Avoid privileging one representation as canonical (they are co-equal and may coexist) and avoid mixing partial Euler and quaternion components without gmeow:eulerOrder.

How to use

• Mint Orientation and fill whichever facet applies — quaternion (X/Y/Z/W), Euler (yaw/pitch/roll + gmeow:eulerOrder), or compass (heading/bearing); multiple facets may co-occur.

Examples

• ex:ori a gmeow:Orientation; gmeow:quaternionX 0.0; gmeow:quaternionY 0.0; gmeow:quaternionZ 0.0; gmeow:quaternionW 1.0.
