HL7 International / Orders and Observations
A complex extension matching the structure of the V2 OG data type. This is used in the v2-to-fhir mapping IG to capture and preserve the OBX-4 Sub-Id details.
A complex extension for capturing the components that can be used to define the structure of the V2 observation/result segments (OBX) within an observation report segment (OBR) (matches the V2 OG data type).
All FHIR elements must have a @value or children
hasValue() or (children().count() > id.count())
Must have either extensions or value[x], not both
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
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 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.
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.
The Original Sub-Identifier component represents the original data type used in OBX4 to enable backwards compatibility to continue use of the original format to provide OBX segment grouping.
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.
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).
The Group component indicates the group and its sequence within the OBR segment that the OBX segment is a part of.
The Sequence component indicates the sequence within the group as defined in OG-2.
The Identifier component enables assignment of an identifier to a result component, for example an isolate in a microbiology message.
