2. Library.implicitRules
Definition

A reference to a set of rules that were followed when the resource was constructed, and which must be understood when processing the content. Often, this is a reference to an implementation guide that defines the special rules along with other profiles etc.

ShortA set of rules under which this content was created
Comments

Asserting this rule set restricts the content to be only understood by a limited set of trading partners. This inherently limits the usefulness of the data in the long term. However, the existing health eco-system is highly fractured, and not yet ready to define, collect, and exchange data in a generally computable sense. Wherever possible, implementers and/or specification writers should avoid using this element. Often, when used, the URL is a reference to an implementation guide that defines these special rules as part of it's narrative along with other profiles, value sets, etc.

10. Library.modifierExtension
Definition

May be used to represent additional information that is not part of the basic definition of the resource and that modifies the understanding of the element that contains it and/or the understanding of the containing element's descendants. Usually modifier elements provide negation or qualification. To make the use of extensions safe and manageable, there is a strict set of governance applied to the definition and use of extensions. Though any implementer is allowed to define an extension, there is a set of requirements that SHALL be met as part of the definition of the extension. Applications processing a resource are required to check for modifier extensions.

Modifier extensions SHALL NOT change the meaning of any elements on Resource or DomainResource (including cannot change the meaning of modifierExtension itself).

ShortExtensions that cannot be ignored
Comments

There can be no stigma associated with the use of extensions by any application, project, or standard - regardless of the institution or jurisdiction that uses or defines the extensions. The use of extensions is what allows the FHIR specification to retain a core level of simplicity for everyone.

TypeExtension

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.

ShortWhat FHIR query?
Comments

Supports communicating a FHIR query (or set of queries) for the given data requirement. The query is server-specific, and will need to be created as informed by a CapabilityStatement. The $data-requirements operation should be expected to be able to provide an Endpoint or CapabilityStatement to provide this information.; If no endpoint or capability statement is provided, the capability statement of the server performing the operation is used.

Definition

A human-readable narrative that contains a summary of the resource and can be used to represent the content of the resource to a human. The narrative need not encode all the structured data, but is required to contain sufficient detail to make it "clinically safe" for a human to just read the narrative. Resource definitions may define what content should be represented in the narrative to ensure clinical safety.

ShortText summary of the resource, for human interpretation
Comments

Contained resources do not have narrative. Resources that are not contained SHOULD have a narrative. In some cases, a resource may only have text with little or no additional discrete data (as long as all minOccurs=1 elements are satisfied). This may be necessary for data from legacy systems where information is captured as a "text blob" or where text is additionally entered raw or narrated and encoded information is added later.

Comments

Can be a urn:uuid: or a urn:oid: but real http: addresses are preferred. Multiple instances may share the same URL if they have a distinct version.

The determination of when to create a new version of a resource (same url, new version) vs. defining a new artifact is up to the author. Considerations for making this decision are found in Technical and Business Versions.

In some cases, the resource can no longer be found at the stated url, but the url itself cannot change. Implementations can use the meta.source element to indicate where the current master source of the resource can be found.

Allows the library to be referenced by a single globally unique identifier.

26. Library.identifier
Definition

A formal identifier that is used to identify this library when it is represented in other formats, or referenced in a specification, model, design or an instance. e.g. CMS or NQF identifiers for a measure artifact. Note that at least one identifier is required for non-experimental active artifacts.

ShortAdditional identifier for the library
Comments

Typically, this is used for identifiers that can go in an HL7 V3 II (instance identifier) data type, and can then identify this library outside of FHIR, where it is not possible to use the logical URI.

NoteThis is a business identifier, not a resource identifier (see discussion)

28. Library.version
Definition

The identifier that is used to identify this version of the library when it is referenced in a specification, model, design or instance. This is an arbitrary value managed by the library 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. To provide a version consistent with the Decision Support Service specification, use the format Major.Minor.Revision (e.g. 1.0.0). For more information on versioning knowledge assets, refer to the Decision Support Service specification. Note that a version is required for non-experimental active artifacts.

ShortBusiness version of the library
Comments

There may be different library instances that have the same identifier but different versions. The version can be appended to the url in a reference to allow a reference to a particular business version of the library with the format [url]|[version].

NoteThis is a business versionId, not a resource version id (see discussion)

Definition

Code filters specify additional constraints on the data, specifying the value set of interest for a particular element of the data. Each code filter defines an additional constraint on the data, i.e. code filters are AND'ed, not OR'ed.

126. Library.dataRequirement.codeFilter.extension
Definition

May be used to represent additional information that is not part of the basic definition of the element. To make the use of extensions safe and manageable, there is a strict set of governance applied to the definition and use of extensions. Though any implementer can define an extension, there is a set of requirements that SHALL be met as part of the definition of the extension.

There can be no stigma associated with the use of extensions by any application, project, or standard - regardless of the institution or jurisdiction that uses or defines the extensions. The use of extensions is what allows the FHIR specification to retain a core level of simplicity for everyone.

128. Library.dataRequirement.codeFilter.path
Definition

The code-valued attribute of the filter. The specified path SHALL be a FHIRPath resolveable on the specified type of the DataRequirement, and SHALL consist only of identifiers, constant indexers, and .resolve(). The path is allowed to contain qualifiers (.) to traverse sub-elements, as well as indexers ([x]) to traverse multiple-cardinality sub-elements (see the Simple FHIRPath Profile for full details). Note that the index must be an integer constant. The path must resolve to an element of type code, Coding, or CodeableConcept.
