Overview

The openEHR Common Information Model defines various abstract concepts and design patterns used in higher level openEHR models.

The archetyped package is informed by a number of design principles, centred on the concept of 'two-level' modelling. These principles are described in detail in [1]. The generic package contains classes forming 'analysis patterns' which are generic across the domain, mostly to do with referencing demographic entities from within other data including PARTICIPATION, PARTY_PROXY, ATTESTATION and so on.

The directory package provides a simple reusable abstraction of a versioned folder structure.

The change_control package defines the generalised semantics of changes to a logical repository, such as an EHR, over time. Each item in such a repository is version-controlled to allow the repository as a whole to be properly versioned in time. The semantics described are in response to medicolegal requirements defined in [2], and in the ISO Technical Specification ISO 18308. Both of these requirements specifications mention specifically the version control of the health record.

The resource package defines semantics of an online authored resource, such as a document, and supports multiple language translations, descriptive meta-data and revision history.
