What API and data model would support a new Premiere Pro workflow for enterprise teams

Problem Statement Description

Product context: Adobe is a creative, document, and marketing software company; its products include Creative Cloud, Photoshop, Illustrator, Acrobat, Adobe Express, Firefly, and Experience Cloud.

Enterprise creative teams using Premiere Pro often coordinate video projects across editors, producers, brand reviewers, legal approvers, asset managers, and marketing operations teams. A new workflow is being considered to make project collaboration, asset handoff, review status, and publishing readiness easier to manage across Premiere Pro and enterprise systems.

You are asked to define the API and data model that would support this workflow. The focus is not on designing the UI, but on how the underlying platform should represent projects, media assets, timelines, comments, versions, permissions, approvals, and integrations so that enterprise teams can reliably build workflows on top of Premiere Pro.

Assume the workflow must support professional creative depth, enterprise-grade trust, collaboration, auditability, and integration with systems such as asset management, campaign planning, identity management, and potentially AI-assisted editing or metadata generation. The design should account for both Premiere Pro users and external enterprise applications that may need to read, update, or subscribe to workflow state.

The experience should consider:

- Core user roles, such as editors, producers, reviewers, admins, legal approvers, and external collaborators

- Key workflow objects, including projects, sequences, clips, media assets, comments, versions, tasks, approvals, and exports

- API capabilities needed for create/read/update actions, search, permissions, status changes, notifications, and event subscriptions

- Data model relationships between creative assets, timeline edits, review feedback, project versions, and enterprise metadata

- Reliability expectations around sync, conflict handling, offline edits, large media files, and long-running processing jobs

- Privacy, security, access control, audit logs, tenant isolation, and compliance needs for enterprise customers

- Integration points with Adobe products, enterprise DAMs, marketing systems, identity providers, and automation tools

- Observability, rollout strategy, developer usability, backward compatibility, and operational trade-offs

Your goal is to describe a clear technical product approach for the APIs and data model that would make this Premiere Pro enterprise workflow scalable, secure, extensible, and useful for both creative teams and enterprise platform integrators.
