Debrief Maritime Analysis Schemas¶
LinkML schemas for Debrief v4.x maritime tactical analysis platform. Defines GeoJSON profile extensions for tracks and reference locations. This is a tracer bullet implementation covering core entity types.
URI: https://debrief.info/schemas/debrief
Name: debrief
Featured Classes¶
The schemas below see the most use across the Debrief codebase. Start here for a quick tour; the full alphabetical tree is below.
Plot features (GeoJSON)¶
These classes define what actually gets drawn on the map and persisted in a STAC item's GeoJSON payload.
- TrackFeature — vessel track with timestamped positions and styling
- ReferenceLocation — fixed reference point or set of points
- SensorData — named sensor and its bearing/range contact series
- SensorContact — a single bearing / range observation
Analysis tooling¶
Metadata that describes the analysis tools exposed by debrief-calc and their inputs.
- Tool — analysis operation with name, version, selection requirements
- ToolParameter — typed parameter declaration (string / number / bool / enum)
- SelectionRequirement — feature-kind and cardinality constraints
Provenance and replay¶
Every transformation records lineage so it can be replayed — these classes capture that chain.
- LogEntry — activity record (what ran, when, against which features)
- WasGeneratedBy — W3C PROV term linking outputs to tool + parameters
- ParameterValue — typed parameter value preserved for replay
- InputFeatureState — pre-operation feature snapshot
Session state (live plot)¶
The shape of the in-memory state a VS Code / web-shell session exposes to the rest of the app.
- GeoJSONFeature — tool-result feature layer entry
- FeatureSelection — currently-selected feature identifiers
- ViewportPolygon — 4-corner polygon describing current view
- TimeInstant — a single point in time (epoch + ISO forms)
- TimeRange — a temporal interval (start, end)
Catalog and platform metadata¶
How Debrief identifies vessels and discovers their metadata from STAC catalogs.
- PlatformRecord — resolved metadata for a single platform (ship, aircraft, etc.)
- BranchRecord — reference to a branched plot in the STAC catalog
Styling¶
- PositionStyle — default styling applied to track positions
