0. Identifier | |
Definition | Electronic Transfer of Prescription (ETP) prescription identifier assigned by an ETP vendor, e.g. ERx or Medisecure, to a prescription. This identifier is the assigned numeric value of the barcode on a prescription instance. An identifier - identifies some entity uniquely and unambiguously. Typically this is used for business identifiers. |

Summary | true |
Requirements | Allows the appropriate identifier for a particular context of use to be selected from among a set of identifiers. |
Invariants | ele-1: All FHIR elements must have a @value or children (hasValue() or (children().count() > id.count())) |
4. Identifier.type | |
Definition | A coded type for the identifier that can be used to determine which identifier to use for a specific purpose. |
Short | Coded identifier type for ETP prescription identifierDescription of identifier |
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. |

6. Identifier.system | |
Definition | Establishes the namespace for the value - that is, a URL that describes a set values that are unique. |

Comments | Identifier.system is always case sensitive. |
Control | 10..1 |
Type | uri |
Is Modifier | false |
Primitive Value | This primitive element may be present, or absent, or replaced by an extension |
Summary | true |
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. |
Example | <br/><b>General</b>:http://www.acme.com/identifiers/patient |
Invariants | ele-1: All FHIR elements must have a @value or children (hasValue() or (children().count() > id.count())) |
8. Identifier.value | |
Definition | The portion of the identifier typically relevant to the user and which is unique within the context of the system. |
Short | ETP prescription identifierThe value that is unique |
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. 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. |

Comments | This is generally not the same as the Resource.text of the referenced resource. The purpose is to identify what's being referenced, not to fully describe it. |

4. Identifier.extension | |

Short | Additional content defined by implementations |
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. |

Slicing | This element introduces a set of slices on Identifier.assigner.extension . The slices areUnordered and Open, and can be differentiated using the following discriminators: |
22. Identifier.assigner.reference | |
Definition | A reference to a location at which the other resource is found. The reference may be a relative reference, in which case it is relative to the service base URL, or an absolute URL that resolves to the location where the resource is found. The reference may be version specific or not. If the reference is not to a FHIR RESTful server, then it should be assumed to be version specific. Internal fragment references (start with '#') refer to contained resources. |
Short | Literal reference, Relative, internal or absolute URL |
Comments | Using absolute URLs provides a stable scalable approach suitable for a cloud/web context, while using relative/logical references provides a flexible approach suitable for use when trading across closed eco-system boundaries. Absolute URLs do not need to point to a FHIR RESTful server, though this is the preferred approach. If the URL conforms to the structure "/[type]/[id]" then it should be assumed that the reference is to a FHIR RESTful server. |

Summary | true |
Invariants | ele-1: All FHIR elements must have a @value or children (hasValue() or (children().count() > id.count()) ) |
24. Identifier.assigner.type | |
Definition | The expected type of the target of the reference. If both Reference.type and Reference.reference are populated and Reference.reference is a FHIR URL, both SHALL be consistent. The type is the Canonical URL of Resource Definition that is the type this reference refers to. References are URLs that are relative to http://hl7.org/fhir/StructureDefinition/ e.g. "Patient" is a reference to http://hl7.org/fhir/StructureDefinition/Patient. Absolute URLs are only allowed for logical models (and can only be used in references in logical models, not resources). |
Short | Type the reference refers to (e.g. "Patient") |
Comments | This element is used to indicate the type of the target of the reference. This may be used which ever of the other elements are populated (or not). In some cases, the type of the target may be determined by inspection of the reference (e.g. a RESTful URL) or by resolving the target of the reference; if both the type and a reference is provided, the reference SHALL resolve to a resource of the same type as that specified. |
Control | 0..1 |
Binding | Unless not suitable, these codes SHALL be taken from ResourceType (extensible to http://hl7.org/fhir/ValueSet/resource-types )Aa resource (or, for logical models, the URI of the logical model). |

Primitive Value | This primitive element may be present, or absent, or replaced by an extension |
Summary | true |
Invariants | ele-1: All FHIR elements must have a @value or children (hasValue() or (children().count() > id.count()) ) |
26. Identifier.assigner.identifier | |
Definition | 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. |
Short | Logical reference, when literal reference is not known |
Comments | 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). |
