works across 8-13 publishers +- **Faster campaign launch** with pre-tested formats +- **Focus budget** on optimization vs. production + +#### For Publishers +- **Reduced friction** in campaign onboarding +- **Faster time-to-revenue** with standard assets +- **Differentiation through context** not specifications +- **Higher fill rates** from easier advertiser adoption + +### Migration Path + +1. **Audit** current custom formats against foundational categories +2. **Map** existing formats to foundational equivalents +3. **Document** any essential customizations +4. **Implement** foundational format support alongside custom +5. **Measure** performance and adoption rates +6. **Optimize** based on results + +## Format Extension Mechanism + +Publishers should extend standard formats rather than creating custom ones, except for truly unique inventory that doesn't fit any standard pattern. + +### When to Extend vs. Create New + +#### Always Extend When: +- Your format is a variation of display, video, audio, or rich media +- The core creative assets match a standard format +- Only placement, timing, or interaction details differ +- You want to accept standard creative assets + +#### Only Create Custom When: +- The format requires fundamentally different assets +- No standard format can reasonably be adapted +- The format is truly unique to your platform (e.g., AR experiences, voice interfaces) + +### Extension Pattern + +Publishers extend formats by declaring the base format and their modifications: + +```json +{ + "format_id": "publisher_premium_canvas", + "extends": "foundational_immersive_canvas", + "publisher": "example_publisher", + "name": "Premium Story Canvas", + "modifications": { + "placement": { + "positions": ["hero", "mid_article"], +

"max_length": 15 + } + } + } +} +``` + +### Benefits of Extension + +1. **Advertiser Efficiency**: One creative works across all publishers supporting the base format +2. **Clear Compatibility**: Buyers instantly know which creatives will work +3. **Innovation Focus**: Publishers compete on performance, not specifications +4. **Faster Adoption**: Pre-tested formats reduce integration time + +### Standard Extension Points + +Publishers can modify these aspects without breaking compatibility: + +#### Timing & Triggers +```json +{ + "timing": { + "autoplay_delay": "3s", + "expansion_trigger": "user_interaction", + "collapse_behavior": "auto_15s" + } +} +``` + +#### Data Enhancement +```json +{ + "data_enhancement": { + "contextual_targeting": true, +

["scroll_depth", "interaction_rate"], + "attribution_window": "7_days", + "viewability_standard": "publisher_custom" + } +} +``` + +### Declaring Extensions in Capabilities + +Publishers should declare both their base format support and extensions: + +```json +{ + "supported_formats": [ + { + "format_id": "foundational_immersive_canvas", + "supported": true, + "publisher_variants": [ + { + "variant_id": "premium_story_canvas", + "extends": "foundational_immersive_canvas", + "modifications": { + "placement": ["hero", "mid_article"], + "min_spend": 5000 + } + } + ] + } + ] +} +``` + +### Creative Submission with Extensions + +When submitting creatives, buyers can indicate extension compatibility: + +```json +{ + "creative": { + "format_id": "foundational_immersive_canvas", + "compatible_extensions": ["*"], // Accepts all extensions + "assets": { + // Standard assets that work everywhere + } + } +} +``` + +Or restrict to specific extensions: + +```json +{ +
