An individual or organization primarily responsible for review of some aspect of the artifact.

The status of this artifact. Enables tracking the life-cycle of the content.

A short, descriptive, user-friendly title for the artifact.

Descriptive topics related to the content of the artifact. Topics provide a high-level categorization of the artifact that can be useful for filtering and searching.

An absolute URI that is used to identify this artifact when it is referenced in a specification, model, design or an instance; also called its canonical identifier. This **SHOULD** be globally unique and **SHOULD** be a literal address at which an authoritative instance of this artifact is (or will be) published. This URL can be the target of a canonical reference. It **SHALL** remain the same when the artifact is stored on different servers.

Describes the clinical usage of the artifact.

The artifact was developed with a focus and intent of supporting the contexts that are listed. These contexts may be general categories (gender, age, …) or may be references to specific programs (insurance plans, studies, …) and may be used to assist with indexing and searching for appropriate artifact instances.

The identifier that is used to identify this version of the artifact when it is referenced in a specification, model, design or instance. This is an arbitrary value managed by the artifact author and is not expected to be globally unique. For example, it might be a timestamp (e.g. yyyymmdd) if a managed version is not available. There is also no expectation that versions can be placed in a lexicographical sequence.

Indicates the mechanism used to compare versions to determine which is more current.

Describes the versioning policy of the artifact.

A comment containing additional documentation, a review comment, usage guidance, or other relevant information from a particular user.

Specifies a term and its associated definition.

Specifies whether the related artifact is defining a primary citation for the artifact (i.e. one that should appear in the narrative for the artifact specification.

Specifies the expansion parameters that should be used to expand the ValueSet, or any ValueSets in the Library (or referenced by components of the Library).

Specifies the type of resource the canonical references.

Defines the scope of an artifact as a string of the form {namespace-name}[@{namespace-uri}]. Namespace name **SHALL** be a valid NPM package id, and namespace uri **SHALL** be a valid uri. For FHIR implementation guides, scope is inferred using the package id and the base canonical. e.g. fhir.cqf.common@http://fhir.org/guides/cqf/common. This extension can be used on Implementation Guides, Libraries, on any knowledge artifact, to declare the scope of the artifact. In the absence of an explicit scope declaration, the scope of an artifact is inferred based on the IG in which the artifact is defined.

Indicates whether the extension or profile element on which it appears represents a dependency that should be traced for the purposes of artifact packaging and distribution

The artifact under test for this test content

Specifies the software systems used in the packaging and testing of knowledge artifacts. Specifically to support explicitly stating which versions of the various software components were used in the authoring, packaging, and testing.

Provides a default value for a parameter definition.

A FHIR Query URL pattern that corresponds to the data specified by the data requirement. If multiple FHIR Query URLs are present, they each contribute to the data specified by the data requirement (i.e. the union of the results of the FHIR Queries represents the complete data for the data requirement). This is not a resolveable URL, in that it will contain 1) No base canonical (i.e. it's a relative query), and 2) Parameters using tokens that are delimited using double-braces and the context parameters are dependent solely on the subjectType, according to the following: Patient: context.patientId, Practitioner: context.practitionerId, Organization: context.organizationId, Location: context.locationId, Device: context.deviceId.

This extension is useful for helping implementing systems determine which data requirements are expected to be most selective of the target population. A common use case is to identify a subset of the data requirements for an artifact as "selective", meaning that they can be used as an initial filter to establish the overall set of data. For example, the selective requirements can be used to construct an initial query or queries for data, with the non-selective requirements used for subsequent filtering on the resulting data. Although this extension may be used by artifact authors as a way to indicate expected selectivity of a data requirement, it will more typically be used by implementers and downstream packaging repositories to indicate selectivity of a data requirement given known data heuristics in particular datasets.

An OperationOutcome that contains any information, warning, and/or error messages that were generated while processing an operation such as $evaluate or $prepopulate.

Allows additional value-based filters to be specified as part of a data requirement.

A module definition library that contains the effective data requirements for an artifact (i.e. the calculated data requirements for the expressions directly referenced by the artifact structure).
