Entity Data Modeler

The Entity Data Modeler (EDM) is a diagram-driven designer for the domain model. It authors *.edm (XML) and *.model (JSON projection) artefacts. From those, the project-generation pipeline emits a complete CRUD application: tables, OData service, REST endpoints, and an Angular UI.

Files

• *.edm - XML domain model, the source of truth edited in the modeler.
• *.model - JSON projection consumed by the application templates.

Both live under /registry/public/<project>/ once published.

Authoring

• Drag entities from the palette onto the canvas.
• Add properties; pick a type, length, nullability, key flag.
• Draw relations between entities to express associations and dependencies.
• Group entities into perspectives to control how they appear in the generated UI.

Save persists the *.edm. Regenerate the *.model projection from the same file when you need the JSON shape.

What it generates

The template-application-* template family consumes the model and emits:

• .table artefacts for every entity.
• An OData v2 service exposing them.
• REST endpoints for CRUD operations.
• A generated Angular UI with master / detail / form views.

See Modeling artefacts and the Workbench perspective.

Underlying library

The canvas is rendered with mxGraph.
