Map of asset IDs to actual asset content. Each key MUST match an asset_id from the format's assets array (e.g., 'banner_image', 'clickthrough_url', 'video_file', 'vast_tag'). The asset_id is the technical identifier used to match assets to format requirements.
Each asset value carries an asset_type discriminator (image, video, audio, vast, daast, text, markdown, url, html, css, webhook, javascript, brief, catalog) that selects the matching asset schema. Validators with OpenAPI-style discriminator support use asset_type to report errors against only the selected branch instead of all branches.
OptionalrightsRights constraints attached to this creative. Each entry represents constraints from a single rights holder. A creative may combine multiple rights constraints (e.g., talent likeness + music license). For v1, rights constraints are informational metadata — the buyer/orchestrator manages creative lifecycle against these terms.
Optionalindustry_Industry-standard identifiers for this specific manifest (e.g., Ad-ID, ISCI, Clearcast clock number). When present, overrides creative-level identifiers. Use when different format versions of the same source creative have distinct Ad-IDs (e.g., the :15 and :30 cuts).
OptionalprovenanceOptionalext
Creative manifest to transform or generate from. For pure generation, this should include the target format_id and any required input assets. For transformation (e.g., resizing, reformatting), this is the complete creative to adapt. When creative_id is provided, the agent resolves the creative from its library and this field is ignored.
