Classes of business

OED began as a property standard. Since v4.0.0 it is a single integrated specification covering four classes of business, rather than separate schemas per class:

Property

The original and most fully developed class. The chapters in this section — import format, asset details, geography and perils, financial terms and reinsurance — describe property business unless they say otherwise.

Cyber

Released as a separate schema in February 2023 and folded into the main schema at v4.0.0. See OED Cyber.

Liability

Released as a separate schema in April 2022 and folded into the main schema at v4.0.0. See OED Liability.

Marine Cargo

Integrated into the main schema at v4.0.0. It follows the same four-file structure as property. There is no separate background document for marine cargo.

A field’s requirement level differs by class, and the field reference gives all four statuses per field — a field required for property may be n/a for cyber, and vice versa.
