Identifier			Element	Element id Identifier Short description An identifier intended for computation Definition A technical identifier - identifies some entity uniquely and unambiguously. Data type Element Constraints ele-1: All FHIR elements must have a @value or children `hasValue() \| (children().count() > id.count())` Mappings rim: n/a v2: CX / EI (occasionally, more often EI maps to a resource id or a URL) rim: II - see see identifier pattern at http://wiki.hl7.org/index.php?title=Common_Design_Patterns#Identifier_Pattern for relevant discussion. The Identifier class is a little looser than the v3 type II because it allows URIs as well as registered OIDs or GUIDs. Also maps to Role[classCode=IDENT] servd: Identifier
id		0..1	string	There are no (further) constraints on this element Element id Identifier.id Short description xml:id (or equivalent in JSON) Definition unique id for the element within a resource (for internal references). This may be any string value that does not contain spaces. Data type string Mappings rim: n/a
extension		0..*	Extension	There are no (further) constraints on this element Element id Identifier.extension Short description Additional Content defined by implementations Alternate names extensions, user content Definition May be used to represent additional information that is not part of the basic definition of the element. In order 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. 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. Data type Extension Sliced: Unordered, Open, by url(Value) Extensions are always sliced by (at least) url Mappings rim: n/a
use	Σ ?!	0..1	codeBinding	Element id Identifier.use Short description usual \| official \| temp \| secondary (If known) Definition The purpose of this identifier. Requirements Allows the appropriate identifier for a particular context of use to be selected from among a set of identifiers. Comments This is labeled as "Is Modifier" because applications should not mistake a temporary id for a permanent one. Applications can assume that an identifier is permanent unless it explicitly says that it is temporary. Data type code Binding Identifies the purpose for this identifier, if known . ?? (required) Constraints ele-1: All FHIR elements must have a @value or children `hasValue() \| (children().count() > id.count())` Mappings v2: N/A rim: Role.code or implied by context
type	Σ	0..1	CodeableConceptBinding	Element id Identifier.type Short description Description of identifier Definition A coded type for the identifier that can be used to determine which identifier to use for a specific purpose. Requirements Allows users to make use of identifiers when the identifier system is not known. Comments 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. Data type CodeableConcept Binding A coded type for an identifier that can be used to determine which identifier to use for a specific purpose. ?? (extensible) Constraints ele-1: All FHIR elements must have a @value or children `hasValue() \| (children().count() > id.count())` Mappings rim: n/a v2: CE/CNE/CWE rim: CD orim: fhir:CodeableConcept rdfs:subClassOf dt:CD v2: CX.5 rim: Role.code or implied by context
system	Σ	0..1	uri	Element id Identifier.system Short description The namespace for the identifier value Definition Establishes the namespace for the value - that is, a URL that describes a set values that are unique. Requirements There are many sets of identifiers. To perform matching of two identifiers, we need to know what set we're dealing with. The system identifies a particular set of unique identifiers. Comments see http://en.wikipedia.org/wiki/Uniform_resource_identifier Data type uri Constraints ele-1: All FHIR elements must have a @value or children `hasValue() \| (children().count() > id.count())` Examples General http://www.acme.com/identifiers/patient or urn:ietf:rfc:3986 if the Identifier.value itself is a full uri Mappings v2: CX.4 / EI-2-4 rim: II.root or Role.id.root servd: ./IdentifierType
value	Σ	0..1	string	Element id Identifier.value Short description The value that is unique Definition The portion of the identifier typically relevant to the user and which is unique within the context of the system. Comments 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 extension. Data type string Constraints ele-1: All FHIR elements must have a @value or children `hasValue() \| (children().count() > id.count())` Examples General 123456 Mappings v2: CX.1 / EI.1 rim: II.extension or II.root if system indicates OID or GUID (Or Role.id.extension or root) servd: ./Value
period	Σ I	0..1	Period	Element id Identifier.period Short description Time period when id is/was valid for use Definition Time period during which identifier is/was valid for use. Comments This is not a duration - that's a measure of time (a separate type), but a duration that occurs at a fixed value of time. A Period specifies a range of time; the context of use will specify whether the entire range applies (e.g. "the patient was an inpatient of the hospital for this time range") or one value from the range applies (e.g. "give to the patient between these two times"). If duration is required, specify the type as Interval\|Duration. Data type Period Constraints ele-1: All FHIR elements must have a @value or children `hasValue() \| (children().count() > id.count())` per-1: If present, start SHALL have a lower value than end `start.empty() or end.empty() or (start <= end)` Mappings rim: n/a v2: DR rim: IVL<TS>[lowClosed="true" and highClosed="true"] or URG<TS>[lowClosed="true" and highClosed="true"] v2: CX.7 + CX.8 rim: Role.effectiveTime or implied by context servd: ./StartDate and ./EndDate
assigner	Σ I	0..1	Reference(http://hl7.org/fhir/StructureDefinition/Organization)	Element id Identifier.assigner Short description Organization that issued id (may be just text) Definition Organization that issued/manages the identifier. Comments The Identifier.assigner may omit the .reference element and only contain a .display element reflecting the name or other textual information about the assigning organization. Data type Reference(http://hl7.org/fhir/StructureDefinition/Organization) Constraints ele-1: All FHIR elements must have a @value or children `hasValue() \| (children().count() > id.count())` ref-1: SHALL have a contained resource if a local reference is provided `reference.startsWith('#').not() or (reference.substring(1).trace('url') in %resource.contained.id.trace('ids'))` Mappings rim: n/a rim: The target of a resource reference is a RIM entry point (Act, Role, or Entity) v2: CX.4 / (CX.4,CX.9,CX.10) rim: II.assigningAuthorityName but note that this is an improper use by the definition of the field. Also Role.scoper servd: ./IdentifierIssuingAuthority
