0. ImplementationGuide
Definition

A set of rules of how a particular interoperability or standards problem is solved - typically through the use of FHIR resources. This resource is used to gather all the parts of an implementation guide into a logical whole and to publish a computable definition of all the parts.

2. ImplementationGuide.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.

Definition

An Extension


May be used to represent additional information that is not part of the basic definition of the resource. 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.

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.

    14. ImplementationGuide.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).

    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.

    Requirements

    Modifier extensions allow for extensions that cannot be safely ignored to be clearly distinguished from the vast majority of extensions which can be safely ignored. This promotes interoperability by eliminating the need for implementers to prohibit the presence of extensions. For further information, see the definition of modifier extensions.

    16. ImplementationGuide.url
    Definition

    An absolute URI that is used to identify this implementation guide 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 at which an authoritative instance of this implementation guide is (or will be) published. This URL can be the target of a canonical reference. It SHALL remain the same when the implementation guide is stored on different servers.

    ShortCanonical identifier for this implementation guide, represented as a URI (globally unique)
    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.

    ShortFHIR Version(s) this Implementation Guide targets
    Comments

    Most implementation guides target a single version - e.g. they describe how to use a particular version, and the profiles and examples etc are valid for that version. But some implementation guides describe how to use multiple different versions of FHIR to solve the same problem, or in concert with each other. Typically, the requirement to support multiple versions arises as implementation matures and different implementation communities are stuck at different versions by regulation or market dynamics.

            Element ImplementationGuide.dependsOn.reason has a context of ImplementationGuide.dependsOn based on following the parent source element upwards and mapping to ImplementationGuide. Element ImplementationGuide.dependsOn.reason has no mapping targets in FHIR R4. Typically, this is because the element has been added (is a new element). This doesn't need to enumerate every resource used, but should give some sense of why the dependency exists. It will be used in the rendered list of dependencies

              Comments

              Element ImplementationGuide.global.type is mapped to FHIR R4 element ImplementationGuide.global.type as RelatedTo. The mappings for ImplementationGuide.global.type do not allow expression of the necessary codes, per the bindings on the source and target. The type must match that of the profile that is referred to but is made explicit here as a denormalization so that a system processing the implementation guide resource knows which resources the profile applies to even if the profile itself is not available.

                    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.

The html language tag in the narrative applies to the narrative. The language tag on the resource may be used to specify the language of other presentations generated from the data in the resource. Not all the content has to be in the base language. The Resource.language should not be assumed to apply to the narrative automatically. If a language is specified, it should it also be specified on the div element in the html (see rules in HTML5 for information about the relationship between xml:lang and the html lang attribute).

                    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.

                    This should never be done when the content can be identified properly, as once identification is lost, it is extremely difficult (and context dependent) to restore it again.

                      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).

                      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.

                      Modifier extensions allow for extensions that cannot be safely ignored to be clearly distinguished from the vast majority of extensions which can be safely ignored. This promotes interoperability by eliminating the need for implementers to prohibit the presence of extensions. For further information, see the definition of modifier extensions.

                      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.

This is an arbitrary value managed by the implementation guide 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.

                      There may be different implementation guide 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 implementation guide with the format [url]|[version].

                      Comments

                      Most implementation guides target a single version - e.g. they describe how to use a particular version, and the profiles and examples etc are valid for that version. But some implementation guides describe how to use multiple different versions of FHIR to solve the same problem, or in concert with each other. Typically, the requirement to support multiple versions arises as implementation matures and different implementation communities are stuck at different versions by regulation or market dynamics.

                          Element ImplementationGuide.dependsOn.reason has a context of ImplementationGuide.dependsOn based on following the parent source element upwards and mapping to ImplementationGuide. Element ImplementationGuide.dependsOn.reason has no mapping targets in FHIR R4. Typically, this is because the element has been added (is a new element). This doesn't need to enumerate every resource used, but should give some sense of why the dependency exists. It will be used in the rendered list of dependencies

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.

                            Modifier extensions allow for extensions that cannot be safely ignored to be clearly distinguished from the vast majority of extensions which can be safely ignored. This promotes interoperability by eliminating the need for implementers to prohibit the presence of extensions. For further information, see the definition of modifier extensions.

                            Usually this is a relative URL that locates the resource within the implementation guide. If you authoring an implementation guide, and will publish it using the FHIR publication tooling, use a URI that may point to a resource, or to one of various alternative representations (e.g. spreadsheet). The tooling will convert this when it publishes it.

                                Element ImplementationGuide.definition.page.source[x] has a context of ImplementationGuide.definition.page based on following the parent source element upwards and mapping to ImplementationGuide. Element ImplementationGuide.definition.page.source[x] has no mapping targets in FHIR R4. Typically, this is because the element has been added (is a new element). If absent and the page isn't a generated page, this may be inferred from the page name by checking input locations. String is used for XHTML content - sent as an escaped string. FHIR tooling can't support 'direct' XHTML anywhere other than in narrative.

                                  Usually this is a relative URL that locates the resource within the implementation guide. If you authoring an implementation guide, and will publish it using the FHIR publication tooling, use a URI that may point to a resource, or to one of various alternative representations (e.g. spreadsheet). The tooling will convert this when it publishes it.
