Structure

Path	Cardinality	Type	Description
Basic	0..*	Basic	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.
Basic.id	0..1	http://hl7.org/fhirpath/System.String	The logical id of the resource, as used in the URL for the resource. Once assigned, this value never changes.
Basic.meta	0..1	Meta	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.
Basic.implicitRules	0..1	uri	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.
Basic.language	0..1	code	The base language in which the resource is written.
Basic.text	0..1	Narrative	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.
Basic.contained	0..*	Resource	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.
Basic.extension	0..*	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.
Basic.modifierExtension	0..*	Extension	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).
Basic.identifier	0..*	Identifier	Identifier assigned to the resource for business purposes, outside the context of FHIR.
Basic.code	1..1	CodeableConcept	Identifies the 'type' of resource - equivalent to the resource name for other resources.
Basic.subject	0..1	Reference	Identifies the patient, practitioner, device or any other resource that is the "focus" of this resource.
Basic.created	0..1	date	Identifies when the resource was first created.
Basic.author	0..1	Reference	Indicates who was responsible for creating the resource instance.

Search Parameters

Name	Type	Description	Expression
_text	string	Search on the narrative of the resource
_content	string	Search on the entire content of the resource
_filter	token	Filter search parameter which supports a more sophisticated grammar for searching. See documentation for further details
_has	string	Provides limited support for reverse chaining - that is, selecting resources based on the properties of resources that refer to them (instead of chaining where resources can be selected based on the properties of resources that they refer to). See the FHIR search page for further documentation
_id	token	Logical id of this artifact	Resource.id
_lastUpdated	date	When the resource version last changed	Resource.meta.lastUpdated
_list	string	All resources in nominated list (by id, Type/id, url or one of the magic List types)
_profile	uri	Profiles this resource claims to conform to	Resource.meta.profile
_query	token	A custom search profile that describes a specific defined query operation
_security	token	Security Labels applied to this resource	Resource.meta.security
_source	uri	Identifies where the resource comes from	Resource.meta.source
_tag	token	Tags applied to this resource	Resource.meta.tag
_text	string	Search on the narrative text (html) of the resource
_type	token	Used when a search is performed in a context which doesn't limit the search to indicate which types are being searched. See the FHIR search page for further discussion
author	reference	Who created	Basic.author
code	token	Kind of Resource	Basic.code
created	date	When created	Basic.created
identifier	token	Business identifier	Basic.identifier
patient	reference	Identifies the focus of this resource	Basic.subject.where(resolve() is Patient)
subject	reference	Identifies the focus of this resource	Basic.subject
