Open Image Template Schema

How the schema represents prompts, slots, controls, examples, provenance, suggested models, and licensing.

Core fields

Each template includes a standard identifier, schema version, id, title, description, category, visible prompt, negative prompt, slots, controls, suggested models, examples, creator, and license.

Slots

Slots are the main editable variables in a template. A slot has a stable name, a user-facing label, and an example value. For example, a portrait template might expose Subject, Lighting, and Background.

Controls

Controls describe optional prompt-builder choices such as style, color palette, lighting, photography style, material, medium, extra details, and toggles like props or branding space.

Examples and provenance

Examples connect a preview image to a generation date and schema version. This makes it easier to track which schema produced the visible example.
