CesiumJS entities and data sources - Entity, EntityCollection, DataSource, GeoJsonDataSource, KmlDataSource, CzmlDataSource, Graphics types, PathGraphics, PathMode, Visualizers. Use when adding points, labels, models, polygons, polylines, or time-segmented paths, loading GeoJSON/KML/CZML/GPX data, or working with the high-level Entity API.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# CesiumJS Entities & DataSources
> **Version baseline:** CesiumJS 1.144 -- ES module imports: `import { ... } from "cesium";`
> **Ownership rule:** `*Graphics` classes belong here; `*Geometry` classes belong in cesiumjs-primitives. Properties (SampledProperty, CallbackProperty, MaterialProperty subtypes) belong in cesiumjs-time-properties.
## Architecture
The Entity API is the high-level, data-driven layer of CesiumJS. Entities combine position, orientation, and one or more Graphics types into a single object managed by an EntityCollection. DataSources load external formats (GeoJSON, KML, CZML, GPX) and populate an EntityCollection automatically. Visualizers and GeometryUpdaters translate Entity descriptions into Primitives each frame.
```
DataSource --> EntityCollection --> Entity
|-- position / orientation
|-- billboard / point / label / model / polygon / polyline / ...
|-- properties (PropertyBag)
```
- `viewer.entities` is a shortcut to the default DataSource's EntityCollection
- `viewer.dataSources` holds all loaded DataSources; each owns an `EntityCollection`

How to install
mdr add cesiumgs/cesiumjs-skills/cesiumjs-entities@sha256:6f40000ee72318e0The line at the top of this page pins the label git:20260827.49e0612, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
