Basic is used for handling concepts not yet defined in FHIR, narrative-only resources that don't map to an existing resource, and custom resources not appropriate for inclusion in the FHIR specification.
If the resource is contained in another resource, it SHALL NOT contain nested Resources
not(parent::f:contained and f:contained)
If the resource is contained in another resource, it SHALL be referred to from elsewhere in the resource or SHALL refer to the containing resource
contained.where((('#'+id in (%resource.descendants().reference | %resource.descendants().as(canonical) | %resource.descendants().as(uri) | %resource.descendants().as(url))) or descendants().where(reference = '#').exists() or descendants().where(as(canonical) = '#').exists() or descendants().where(as(canonical) = '#').exists()).not()).trace('unmatched', id).empty()
not(exists(for $id in f:contained/*/f:id/@value return $contained[not(parent::*/descendant::f:reference/@value=concat('#', $contained/*/id/@value) or descendant::f:reference[@value='#'])]))
If a resource is contained in another resource, it SHALL NOT have a meta.versionId or a meta.lastUpdated
contained.meta.versionId.empty() and contained.meta.lastUpdated.empty()
not(exists(f:contained/*/f:meta/f:versionId)) and not(exists(f:contained/*/f:meta/f:lastUpdated))
If a resource is contained in another resource, it SHALL NOT have a security label
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.
A resource should have narrative for robust management
The logical id of the resource, as used in the URL for the resource. Once assigned, this value never changes.
The only time that a resource does not have an id is when it is being submitted to the server using a create operation.
The metadata about the resource. This is content that is maintained by the infrastructure. Changes to the content might not always be associated with version changes to the resource.
All FHIR elements must have a @value or children
hasValue() or (children().count() > id.count())
A set of rules under which this content was created
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.
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.
This element is labeled as a modifier because the implicit rules may provide additional knowledge about the resource that modifies it's meaning or interpretation
The base language in which the resource is written.
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).
Text summary of the resource, for human interpretation
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.
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.
These resources do not have an independent existence apart from the resource that contains them - they cannot be identified independently, and nor can they have their own independent transaction scope.
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.
Must have either extensions or value[x], not both
exists(f:extension)!=exists(f:*[starts-with(local-name(.), "value")])
A selection of DICOM SOP instances and/or frames
A selection of DICOM SOP instances and/or frames within a single Study and Series. This might include additional specifics such as an image region, an Observation UID or a Segmentation Number, allowing linkage to an Observation Resource or transferring this information along with the ImagingStudy Resource.
exists(f:extension)!=exists(f:*[starts-with(local-name(.), 'value')])
Unique id for the element within a resource (for internal references). This may be any string value that does not contain spaces.
Extensions are always sliced by (at least) url
The current state of the ImagingSelection resource. This is not the status of any ImagingStudy, ServiceRequest, or Task resources associated with the ImagingSelection.
Additional content defined by implementations
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.
Source of the definition for the extension code - a logical name or a URL.
The definition may point directly to a computable or human-readable definition of the extensibility codes, or it may be a logical URI as declared in some other specification. The definition SHALL be a URI for the Structure Definition defining the extension.
Date / Time when this imaging selection was created
The date and time this imaging selection was created.
Selector of the instances (human or machine)
Selector of the instances – human or machine.
Distinguishes the type of involvement of the performer.

Value of extension - must be one of a constrained set of the data types (see [Extensibility](http://hl7.org/fhir/R4/extensibility.html) for a list).
A list of the diagnostic requests that resulted in this imaging selection being performed.
This cross-version extension represents ImagingSelection.category from http://hl7.org/fhir/StructureDefinition/ImagingSelection|5.0.0 for use in FHIR R4.
The Study Instance UID for the DICOM Study from which the images were selected.
The imaging study from which the imaging selection is derived
The imaging study from which the imaging selection is made.
The network service providing retrieval for the images referenced in the imaging selection
The network service providing retrieval access to the selected images, frames, etc. See implementation notes for information about using DICOM endpoints.
The Series Instance UID for the DICOM Series from which the images were selected.
The Series Number for the DICOM Series from which the images were selected.
The Frame of Reference UID for the selected images
The Frame of Reference UID identifying the coordinate system that conveys spatial and/or temporal information for the selected images or frames.
The anatomic structures examined. See DICOM Part 16 Annex L (http://dicom.nema.org/medical/dicom/current/output/chtml/part16/chapter_L.html) for DICOM to SNOMED-CT mappings.
A reference to a concept - e.g. the information is identified by its general class to the degree of precision found in the terminology.
A reference to a resource the provides exact details about the information being referenced.
Data type name for ImagingSelection.bodySite from FHIR R5
Value of extension - must be one of a constrained set of the data types (see [Extensibility](http://hl7.org/fhir/R5/extensibility.html) for a list).
Related resource that is the focus for the imaging selection
The actual focus of an observation when it is not the patient 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.
The SOP Instance UID for the selected DICOM instance.
The Instance Number for the selected DICOM instance.
The SOP Class UID for the selected DICOM instance.
Selected subset of the SOP Instance. The content and format of the subset item is determined by the SOP Class of the selected instance. May be one of: - A list of frame numbers selected from a multiframe SOP Instance. - A list of Content Item Observation UID values selected from a DICOM SR or other structured document SOP Instance. - A list of segment numbers selected from a segmentation SOP Instance. - A list of Region of Interest (ROI) numbers selected from a radiotherapy structure set SOP Instance.
point | polyline | interpolated | circle | ellipse
Specifies the coordinates that define the image region
The coordinates describing the image region. Encoded as a set of (column, row) pairs that denote positions in the selected image / frames specified with sub-pixel resolution. The origin at the TLHC of the TLHC pixel is 0.0\0.0, the BRHC of the TLHC pixel is 1.0\1.0, and the BRHC of the BRHC pixel is the number of columns\rows in the image / frames. The values must be within the range 0\0 to the number of columns\rows in the image / frames.
point | multipoint | polyline | polygon | ellipse | ellipsoid
The coordinates describing the image region. Encoded as an ordered set of (x,y,z) triplets (in mm and may be negative) that define a region of interest in the patient-relative Reference Coordinate System defined by ImagingSelection.frameOfReferenceUid element.
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).
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://hl7.org/fhir/R4/extensibility.html#modifierExtension).
Modifier extensions are expected to modify the meaning or interpretation of the resource that contains them
Identifier assigned to the resource for business purposes, outside the context of FHIR.
Identifies the 'type' of resource - equivalent to the resource name for other resources.
Because resource references will only be able to indicate 'Basic', the type of reference will need to be specified in a Profile identified as part of the resource. Refer to the resource notes section for information on appropriate terminologies for this code. This element is labeled as a modifier because it defines the meaning of the resource and cannot be ignored.
Must be able to distinguish different types of Basic resources.
This element determines what kind of resource is being represented which drives the meaning of all of the other elements.
Codes for identifying types of resources not yet defined by FHIR.
Identifies the patient, practitioner, device or any other resource that is the "focus" of this resource.
Optional as not all potential resources will have subjects. Resources associated with multiple subjects can handle this via extension.
Needed for partitioning the resource by Patient.
./participation[typeCode='SBJ'] (possibly through a ControlAct and Role)
Identifies when the resource was first created.
Allows ordering resource instances by time.
./participation[typeCode='AUT']/time (possibly through a ControlAct and Role)
Indicates who was responsible for creating the resource instance.
./participation[typeCode='SUB'] (possibly through a ControlAct and Role)
