Product Types

Product types define what kind of content a product represents and what capabilities are available.

Available Types

Legacy-only types (Video Course, Audiobook) have distributable assets that cannot currently be assembled from Content Lake documents. Content Lake-only types (Interactive) exist only as assembled experiences. Book supports both models.

Version Pinning

When attaching a Content Lake document to a product, the attachment includes a version specifier:

• version=latest — the product tracks the latest Content Lake version. When the Content Lake document is updated, the product automatically reflects the new content.
• version=<id> — the product is pinned to a specific Content Lake version. Updates to the source document are ignored until someone explicitly re-pins.

The product-level concurrent flag controls the default:

• concurrent=true — new attachments default to version=latest.
• concurrent=false — new attachments require an explicit version ID.

        B["Ch 2 — Doc B v7 (pinned)"]
        C["Ch 3 — Doc C latest (override)"]
    end

A single product can mix pinned and latest-tracking documents. This is useful when most chapters are stable but one chapter covers a rapidly evolving topic.

Re-pinning

Re-pinning updates a document attachment from one version to another. This emits a packt.products.content.v1.updated event so downstream consumers know the product's content has changed.

RETIRED and WITHDRAWN are terminal states. All state transitions emit lifecycle events on the products EventBridge bus.

Product Metadata

Identifiers

Each product has a platform-generated ID (UUIDv7). Products that are distributed externally also carry ISBNs — one per format. ISBNs are assigned during the lifecycle, not at creation.

Core Fields

Pricing

Pricing is defined per product with a base price and optional territory overrides.

Territory prices are independent — each territory specifies its own amount and currency. There is no automatic currency conversion.

Available Formats

For Content Lake-backed products, formats are determined by product type. For legacy products, the format is whatever was uploaded.

Roadmap

• More book formats (ePub 2)
• Courses (SCORM)
