Stream

• CURIE: gmeow:Stream

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

A time-ordered sequence of observations or samples produced by a sensor or platform over a time interval. The ordering of samples is implicit via their individual timestamps, not asserted as a list structure (Principle 12). A stream is the canonical source from which a continuous trajectory may be derived by the solver layer.

Structure

Subclass of: gmeow:Entity, gufo:Object

Practical Pattern

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

Common Companion Terms

gmeow:Entity

Usage Advice

Use when

• Use to group a time-ordered run of observations or samples about one entity from a sensor or platform — the canonical source a solver derives a continuous trajectory from (no list structure is asserted).

Avoid when

• Avoid for a single isolated reading (use a bare Observation) and avoid encoding sample order as an RDF list — ordering is implicit via each sample's timestamp (Principle 12), and the interpolated trajectory is a solver concern.

How to use

• Mint the Stream, bind its subject with the functional gmeow:streamOf, attach readings via gmeow:streamSample, name gmeow:streamPlatform / gmeow:streamSensor, and bound it with the functional gmeow:streamInterval; an entity reaches its streams through gmeow:hasStream.

Examples

• ex:roverTrack a gmeow:Stream; gmeow:streamOf ex:rover; gmeow:streamSample ex:fix1.
