XOStyyppiset

XOStyyppiset is a Finnish term used in certain technical and academic contexts to describe typological classes within a broader concept known as XOS. The term is formed by combining XOS with the Finnish plural noun ending -tyyppiset, meaning "types of XOS" or "XOS types." In practice, XOStyyppiset designate alternative object types that share a core set of characteristics.

In usage, a type is defined as a feature profile that combines attributes along dimensions often labeled X, O and S. The exact interpretation of X, O and S depends on the field and author. The approach is typological rather than prescriptive: different sources may define different type sets and criteria, and types may be updated as the underlying framework evolves.

Typical examples include:

- Type A: core functionality with modular extensions, focusing on interoperability.

- Type B: operational efficiency with strict compatibility requirements.

- Type C: security-centric configuration with extended audit capabilities.

XOStyyppiset are used in documentation and modeling to help compare configurations, plan deployments, or reason about compatibility between components. The concept is not tied to a single standardized framework, and its definitions may vary between organizations. See also XOS and typology in information systems.
