2. SubscriptionTopic.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.

4. SubscriptionTopic.extension
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.

    Element SubscriptionTopic.versionAlgorithm[x] has a context of SubscriptionTopic based on following the parent source element upwards and mapping to SubscriptionTopic. Element SubscriptionTopic.versionAlgorithm[x] has no mapping targets in FHIR R4B. Typically, this is because the element has been added (is a new element). An externally-defined extension that has been mapped as the representation of FHIR R5 element SubscriptionTopic.versionAlgorithm[x]: http://hl7.org/fhir/StructureDefinition/artifact-versionAlgorithm. If set as a string, this is a FHIRPath expression that has two additional context variables passed in - %version1 and %version2 and will return a negative number if version1 is newer, a positive number if version2 and a 0 if the version ordering can't be successfully be determined.

    12. SubscriptionTopic.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
    Is Modifiertrue because Modifier extensions are expected to modify the meaning or interpretation of the resource that contains them

    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.

    14. SubscriptionTopic.url
    Definition

    An absolute URI that is used to identify this subscription topic 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 subscription topic is (or will be) published. This URL can be the target of a canonical reference. It SHALL remain the same when the subscription topic is stored on different servers.

    ShortCanonical identifier for this subscription topic definition, 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.

      Element SubscriptionTopic.url is mapped to FHIR R4B element SubscriptionTopic.url as Equivalent. An externally-defined extension that has been mapped as the representation of FHIR R5 element SubscriptionTopic.url: http://hl7.org/fhir/StructureDefinition/artifact-url. Can be a urn:uuid: or a urn:oid: but real http/s: 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.

      When this is a locally defined topic or derived from a topic defined in the FHIR spec or an IG, this uniquely identifies the topic and functionality. Ideally this URL resolves to documentation about the use cases.

      When this is a topic derived from another topic (e.g., it adds additional filters or functionality to a topic defined in an IG), then this URL should be different than the base and the derivedFromCanonical should be filled out with the unique uri as defined in the IG.

      When this is a direct implementation from another IG or registered topic (with no additional filters, etc., so not derived), then this url is the unique url for this topic as defined by the IG.

              ShortR5: Business identifier for subscription topic
              Comments

              Element SubscriptionTopic.identifier is mapped to FHIR R4B element SubscriptionTopic.identifier as Equivalent. An externally-defined extension that has been mapped as the representation of FHIR R5 element SubscriptionTopic.identifier: http://hl7.org/fhir/StructureDefinition/artifact-identifier. Note: This is a business identifier, not a resource identifier (see discussion). It is best practice for the identifier to only appear on a single resource instance, however business practices may occasionally dictate that multiple resource instances with the same identifier can exist - possibly even with different resource types. For example, multiple Patient and a Person resource instance might share the same social insurance number.

                                          Element SubscriptionTopic.effectivePeriod is mapped to FHIR R4B element SubscriptionTopic.effectivePeriod as Equivalent. An externally-defined extension that has been mapped as the representation of FHIR R5 element SubscriptionTopic.effectivePeriod: http://hl7.org/fhir/StructureDefinition/artifact-effectivePeriod. The effective period for a SubscriptionTopic determines when the content is applicable for usage and is independent of publication and review dates. For example, a measure intended to be used for the year 2016 would be published in 2015.

Element SubscriptionTopic.canFilterBy.comparator has no mapping targets in FHIR R4B. Typically, this is because the element has been added (is a new element). If no comparators are listed, clients should not expect servers to support any comparators.

                                              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.

                                              Language is provided to support indexing and accessibility (typically, services such as text to speech use the language tag). 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).

Resource definitions may define what content should be represented in the narrative to ensure clinical safety.

                                              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. Contained resources may have profiles and tags In their meta elements, but SHALL NOT have security labels.

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).

                                                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.

                                                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.

An externally-defined extension that has been mapped as the representation of FHIR R5 element SubscriptionTopic.url: http://hl7.org/fhir/StructureDefinition/artifact-url. Can be a urn:uuid: or a urn:oid: but real http/s: 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.

                                                  When this is a locally defined topic or derived from a topic defined in the FHIR spec or an IG, this uniquely identifies the topic and functionality. Ideally this URL resolves to documentation about the use cases.

                                                  When this is a topic derived from another topic (e.g., it adds additional filters or functionality to a topic defined in an IG), then this URL should be different than the base and the derivedFromCanonical should be filled out with the unique uri as defined in the IG.

                                                  When this is a direct implementation from another IG or registered topic (with no additional filters, etc., so not derived), then this url is the unique url for this topic as defined by the IG.

                                                    This element deals only with general categories of identifiers. It SHOULD not be used for codes that correspond 1..1 with the Identifier.system. Some identifiers may fall into multiple categories due to common usage. Where the system is known, a type is unnecessary because the type is always part of the system definition. However systems often need to handle identifiers where the system is not known. There is not a 1:1 relationship between type and system, since many different systems have the same type.

As a result, it may be normalized for comparison purposes (e.g. removing non-significant whitespace, dashes, etc.) A value formatted for human display can be conveyed using the Rendered Value extension. Identifier.value is to be treated as case sensitive unless knowledge of the Identifier.system allows the processer to be confident that non-case-sensitive processing is safe.

                                                    The identifier that is used to identify this version of the subscription topic when it is referenced in a specification, model, design or instance. This is an arbitrary value managed by the Topic 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 are orderable.

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.

This promotes interoperability by eliminating the need for implementers to prohibit the presence of extensions. For further information, see the definition of modifier extensions.

Element SubscriptionTopic.canFilterBy.comparator has no mapping targets in FHIR R4B. Typically, this is because the element has been added (is a new element). If no comparators are listed, clients should not expect servers to support any comparators.

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 can 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).

The use of extensions is what allows the FHIR specification to retain a core level of simplicity for everyone.

This promotes interoperability by eliminating the need for implementers to prohibit the presence of extensions. For further information, see the definition of modifier extensions.

This promotes interoperability by eliminating the need for implementers to prohibit the presence of extensions. For further information, see the definition of modifier extensions.
