    v: When a resource has no narrative, only systems that fully understand the data can display the resource to a human safely. Including a human readable representation in the resource makes for a much more robust eco-system and cheaper handling of resources by intermediary systems. Some ecosystems restrict distribution of resources to only those systems that do fully understand the resources, and as a consequence implementers may believe that the narrative is superfluous. However experience shows that such eco-systems often open up to new participants over time.

comment:
  v: 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.

definition:

comment:
  v: This element is generally omitted in instances submitted in a PUT or POST. Instead, it might be populated by the server when data is received or assigned when crafting the instance when constructing a response. The server / resource manager sets this value; what a client provides can be irrelevant. This is equivalent to the HTTP Last-Modified and SHOULD have the same value on a read interaction. Note that there are scenarios where changes in a resource do not trigger a change in the `lastUpdated` value and there are scenarios where changes in `lastUpdated` are made even though there are no visible changes in the resource. Unless specified otherwise, this element MAY be out of sync with changes in either direction. For example: * If a system uses mapping tables to generate resources (e.g., a facade server), updates to those tables might not be reflected in `lastUpdated` but do result in a difference of retrieved resource content. * If a system generates resources from internal data (e.g., a facade server), the system's internal `lastUpdated` value might be changed due to changes that are not visible on FHIR resources (e.g., extended data has been changed). * If a system updates an element that a particular client does not have access to (e.g., prevented by privacy rules), the `lastUpdated` value might be changed even though there are no visible changes in resource content. Note to server implementers: updating `lastUpdated` too frequently is generally preferred over missing updates. It is better for client to retrieve records too frequently rather than missing updates.

comment:
  v: The exact use of the source (and the possible implied Provenance.entity.role and agent.role) is left to implementer discretion. Only one nominated source is allowed; for additional provenance details, a full Provenance resource should be used. The source may correspond to Provenance.entity.what[x] or Provenance.agent.who[x], though it may be a more general or abstract reference. This element can be used to indicate where the current master source of a resource that has a canonical URL if the resource is no longer hosted at the canonical URL.

short:
  v: A set of rules under which this content was created
definition:
  v: 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. For DomainResources, if more than one implicitRules policy applies, additional policies may be conveyed using the [additionalImplicitRules](https://build.fhir.org/ig/HL7/fhir-extensions/StructureDefinition-additionalImplicitRules.html) extension.
comment:
  v: 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 its narrative along with other profiles, value sets, etc.

comment:
  v: 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.
comment:
  v: Contained resources do not have a 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.

comment:
  v: 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. Contained resources may be a resource type defined in the FHIR specification, or an [additional resource](http://build.fhir.org/resource.html#additional).

definition:
  v: 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 managable, 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).
comment:
  v: 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.
requirements:
  v: 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](http://build.fhir.org/extensibility.html#modifierExtension).

comment:
  v: This value is used in the conditional create to prevent data duplication. PHDs will often re-send already sent data for a variety of reasons. This element is recommended unless the observation contains no timestamp or is a measurement containing a timestamp that is real time. By real time the timestamp reported by the PHD must be later than the current time reported by the PHD before any measurements are received. There might be other means to ascertain whether the data is real time. Temporarily stored data from IEEE 11073-10206 compliant devices, which are required to be deleted the data after sending, can be considered real time. An example of this are temporarily stored observations from a device implementing the Bluetooth SIG GHS profile or implementing another Bluetooth SIG medical sensor device profile.

comment:
  v: 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.
requirements:
  v: Allows users to make use of identifiers when the identifier system is not known.

comment:
  v: Identifier.system is always case sensitive.

comment:
  v: If the value is a full URI, then the system SHALL be urn:ietf:rfc:3986. The value's primary purpose is computational mapping. 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](https://build.fhir.org/ig/HL7/fhir-extensions/StructureDefinition-rendered-value.html)). Identifier.value is to be treated as case sensitive unless knowledge of the Identifier.system allows the processor to be confident that non-case-sensitive processing is safe.

requirements:
  v: 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.

comment:
  v: *All* code-value and, if present, component.code-component.value pairs need to be taken into account to correctly understand the meaning of the observation. All codings in Observation.code are expected to be sufficiently precise to allow a user with the code and value to be able to understand the value - though not all codes will necessarily convey the same level of detail. Codings in Observation.category SHOULD be concepts that are too broad to be able to understand the meaning of the Observation.value without also having an Observation.code. See [Interoperability Issues using code value pairs in FHIR](http://build.fhir.org/observation.html#code-interop) for additional information.

  v: The version of the code system which was used when choosing this code. Note that a well-maintained code system does not need the version reported, because the meaning of codes is consistent across versions. However this cannot consistently be assured, and when the meaning is not guaranteed to be consistent, the version SHOULD be exchanged.
comment:
  v: Where the terminology does not clearly define what string should be used to identify code system versions, the recommendation is to use the date (expressed in FHIR date format) on which that version was officially published as the version date.

  v: The patient, or group of patients, location, device, organization, procedure or practitioner this observation is about and into whose or what record the observation is placed. If the actual focus of the observation is different from the subject (or a sample of, part, or region of the subject), the `focus` element or the `code` itself specifies the actual focus of the observation.
comment:
  v: One would expect this element to be a cardinality of 1..1. The only circumstance in which the subject can be missing is when the observation is made by a device that does not know the patient. In this case, the observation SHALL be matched to a patient through some context/channel matching technique, and at this point, the observation should be updated. The subject of an Observation may in some cases be a procedure. This supports the regulatory inspection use case where observations are captured during inspections of a procedure that is being performed (independent of any particular patient or whether patient related at all).

  v: Observations have no value if you don't know who or what they're about.

short:
  v: What the observation is about, when it is not about the subject of record
definition:
  v: The actual focus of an observation when it is not the subject of record representing something or someone associated with the patient such as a spouse, parent, fetus, or donor. For example, fetus observations in a mother's record. The focus of an observation could also be an existing condition, an intervention, the subject's diet, another observation of the subject, or a body structure such as tumor or implanted device. An example use case would be using the Observation resource to capture whether the mother is trained to change her child's tracheostomy tube. In this example, the child is the patient of record and the mother is the focus. As another use case, a caregiver (RelatedPerson) has back strain and is unable to provide ADL support to a patient (Subject).
comment:
  v: Examples demonstrating the use of subject and focus in an Observation: - A parent is trained to change their child's tracheostomy tube. The child is the subject, and the parent is the focus. - A fetal heart rate recorded in a mother's record. The mother is the subject, and the fetus is the focus. - Features of a body structure, such as a tumor. The patient is the subject, and the specific body structure is the focus. - Metrics captured from a medical device. The patient-attached device is the subject, the specific device metric is the focus, and the observing device itself is referenced in .device.

  v: An observation that is an organizer/grouper does not have a value (or dataAbsentReason) of its own - all values are included in the sub-observations. The sub-observations are linked using hasMember element references (in some instances there may be no hasMember references, as it is possible that the organizer/grouper observation may be created first, and the sub-observations are not created until a later time). An organizer/grouper observation also does not contain any components.

comment:
  v: - An observation may have: 1. a single value here 1. both a value and a set of related or component values 1. only a set of related or component values. - If a value is present, the datatype for this element should be determined by the `code`. - *CodeableConcept* with just a text would be used instead of a string if the field was usually coded, or if the type associated with the `code` defines a coded value. - *Attachment* is used if the observation result value is a binary file such as an image. If the observation result value is derived from the binary file (for example 'X' detected and here is the proof in this image), the binary file may be directly represented using *DocumentReference* and referenced by `derivedFrom`. - For additional guidance, see the [Notes section](http://build.fhir.org/observation.html#notes) below. - See [Interoperability Issues using code value pairs in FHIR](http://build.fhir.org/observation.html#code-interop) for additional information.

Note that a well-maintained code system does not need the version reported, because the meaning of codes is consistent across versions. However this cannot consistently be assured, and when the meaning is not guaranteed to be consistent, the version SHOULD be exchanged.
comment:
  v: Where the terminology does not clearly define what string should be used to identify code system versions, the recommendation is to use the date (expressed in FHIR date format) on which that version was officially published as the version date.

comment:
  v: This element provides essential contextual information that affects how the observation should be interpreted. For example, knowing that a patient is diabetic, fasting, or paraplegic may be critical to properly understanding lab results or other observations. Similarly, information about the timing, view, or imaging mode may be relevant to understanding an imaging measurement. This element is intended for interpretive context and not for conveying order, request, or fulfillment workflow information.

short:
  v: Logical reference, when literal reference is not known
definition:
  v: An identifier for the target resource. This is used when there is no way to reference the other resource directly, either because the entity it represents is not available through a FHIR server, or because there is no way for the author of the resource to convert a known identifier to an actual location. There is no requirement that a Reference.identifier point to something that is actually exposed as a FHIR instance, but it SHALL point to a business concept that would be expected to be exposed as a FHIR instance, and that instance would need to be of a FHIR resource type allowed by the reference.
comment:
  v: When an identifier is provided in place of a reference, any system processing the reference will only be able to resolve the identifier to a reference if it understands the business context in which the identifier is used. Sometimes this is global (e.g. a national identifier) but often it is not. For this reason, none of the useful mechanisms described for working with references (e.g. chaining, includes) are possible, nor should servers be expected to be able resolve the reference. Servers may accept an identifier based reference untouched, resolve it, and/or reject it - see CapabilityStatement.rest.resource.referencePolicy. When both an identifier and a literal reference are provided, the literal reference is preferred. Applications processing the resource are allowed - but not required - to check that the identifier matches the literal reference Applications converting a logical reference to a literal reference may choose to leave the logical reference present, or remove it. Reference is intended to point to a structure that can potentially be expressed as a FHIR resource, though there is no need for it to exist as an actual FHIR resource instance - except in as much as an application wishes to actual find the target of the reference. The content referred to be the identifier must meet the logical constraints implied by any limitations on what resource types are permitted for the reference. For example, it would not be legitimate to send the identifier for a drug prescription if the type were Reference(Observation|DiagnosticReport). One of the use-cases for Reference.identifier is the situation where no FHIR representation exists (where the type is Reference (Any). This element only allows for a single identifier. In the case where additional identifiers are required, use the [additional identifier](https://build.fhir.org/ig/HL7/fhir-extensions/StructureDefinition-additionalIdentifier.html) extension.

comment:
  v: Most observations only have one generic reference range. Systems MAY choose to restrict to only supplying the relevant reference range based on knowledge about the patient (e.g., specific to the patient's age, gender, weight and other factors), but this might not be possible or appropriate. Whenever more than one reference range is supplied, the differences between them SHOULD be provided in the reference range and/or age properties.
requirements:
  v: Knowing what values are considered "normal" can help evaluate the significance of a particular result. Need to be able to provide multiple reference ranges for different contexts.

requirements:
  v: 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](http://build.fhir.org/extensibility.html#modifierExtension).

comment:
  v: When low.comparator is not populated (the low.comparator element was not available prior to FHIR R6), the low bound of the reference range endpoint is inclusive of the value (e.g., reference range is '>=5' - '<=9'). Alternatively, this can be specified explicitly by populating low.comparator = '>='.

definition:
  v: May be used to represent additional information that is not part of the basic definition of the element and that modifies the understanding of the element in which it is contained 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 managable, 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).
comment:
  v: 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.
requirements:
  v: 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](http://build.fhir.org/extensibility.html#modifierExtension).

  v: Why the component result value is missing
definition:
  v: Provides a reason why the expected value in the element Observation.component.value[x] is missing.
comment:
  v: "Null" or exceptional values can be represented two ways in FHIR Observations. One way is to simply include them in the value set and represent the exceptions in the value. For example, measurement values for a serology test could be "detected", "not detected", "inconclusive", or "test not done". The alternate way is to use the value element for actual observations and use the explicit dataAbsentReason element to record exceptional values. For example, the dataAbsentReason code "error" could be used when the measurement was not completed. Because of these options, use-case agreements are required to interpret general observations for exceptional values.
requirements:
  v: For many results it is necessary to handle exceptional values in measurements.

comment:
  v: Historically used for laboratory results (known as 'abnormal flag' ), its use extends to other use cases where coded interpretations are relevant. Often reported as one or more simple compact codes this element is often placed adjacent to the result value in reports and flow sheets to signal the meaning/normalcy status of the result.
requirements:

comment:
  v: Most observations only have one generic reference range. Systems MAY choose to restrict to only supplying the relevant reference range based on knowledge about the patient (e.g., specific to the patient's age, gender, weight and other factors), but this might not be possible or appropriate. Whenever more than one reference range is supplied, the differences between them SHOULD be provided in the reference range and/or age properties.

  v: Extensions that cannot be ignored even if unrecognized
definition:
  v: May be used to represent additional information that is not part of the basic definition of the element and that modifies the understanding of the element in which it is contained 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 managable, 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).
comment:
  v: 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.
requirements:
  v: 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](http://build.fhir.org/extensibility.html#modifierExtension).

comment:
  v: Used when observation has a set of component observations: - An observation may have both a value (e.g. an Apgar score) and component observations (the observations from which the Apgar score was derived). - If a value is present, the datatype for this element should be determined by the `code`. - *CodeableConcept* with just a text would be used instead of a string if the field was usually coded, or if the type associated with the `code` defines a coded value. - *Attachment* is used if the observation result value is a binary file such as an image. If the observation result value is derived from the binary file (for example 'X' detected and here is the proof in this image), the binary file may be directly represented using *DocumentReference* and referenced by `derivedFrom`. - If a value is present, the datatype for this element should be determined by the `code`. - *CodeableConcept* with just a text would be used instead of a string if the field was usually coded, or if the type associated with the `code` defines a coded value. - *Attachment* is used if the observation result value is a binary file such as an image. If the observation result value is derived from the binary file (for example 'X' detected and here is the proof in this image), the binary file may be directly represented using *DocumentReference* and referenced by `derivedFrom`. - For additional guidance, see the [Notes section](http://build.fhir.org/observation.html#notes) below.
