Definitions for the 11179-objectClassProperty extension.
Guidance on how to interpret the contents of this table can be found here.
1. Extension | |
Definition | A quality common to all members of an object class. A property may be any feature that humans naturally use to distinguish one individual object from another. It is the human perception of a single quality of an object class in the real world. It is conceptual and thus has no particular associated means of representation by which the property can be communicated. Optional Extension Element - found in all resources. |
Control | 0..1* |
Comments | ObjectClass and Property are treated as a data model that can be mapped to like any other. This extension merely captures the Property element as a discrete code. The information conveyed here should also be conveyed in human-readable form in the mapping.map element. |
2. Extension.extension | |
Control | 0..0* |
3. Extension.url | |
Fixed Value | http://hl7.org/fhir/StructureDefinition/11179-objectClassProperty |
4. Extension.value[x] | |
Control | 10..1 |
Binding | For example codes, see DataElementSDCObjectClassFor codes, see (unbound) |
Type | Choice of: , date, Meta, Address, Attachment, integer, Count, DataRequirement, Dosage, uuid, Identifier, RatioRange, SampledData, id, positiveInt, Distance, Availability, integer64, Period, Duration, canonical, Range, RelatedArtifact, base64Binary, UsageContext, Timing, decimal, ExtendedContactDetail, CodeableConcept, ParameterDefinition, dateTime, code, string, oid, instant, ContactPoint, HumanName, Money, markdown, Ratio, Age, Reference, TriggerDefinition, Quantity, uri, url, Annotation, ContactDetail, boolean, Expression, CodeableReference, Signature, unsignedInt, time |

Invariants | Defined on this element ele-1: All FHIR elements must have a @value or children (: hasValue() or (children().count() > id.count())) ext-1: Must have either extensions or value[x], not both (: extension.exists() != value.exists()) |
2. Extension.extension | |
Definition | An Extension 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. |
Control | 0..0* |
Type | Extension |
Summary | false |
Alternate Names | extensions, user content |
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. |
Invariants | Defined on this element ele-1: All FHIR elements must have a @value or children (: hasValue() or (children().count() > id.count())) ext-1: Must have either extensions or value[x], not both (: extension.exists() != value.exists()) |
Slicing | This element introduces a set of slices on Extension.extension. The slices are unordered and Open, and can be differentiated using the following discriminators:
|
3. Extension.url | |
Definition | Source of the definition for the extension code - a logical name or a URL. |
Control | 1..1 |
Type | uri |
XML Representation | In the XML format, this property is represented as an attribute. |
Summary | false |
Comments | 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. |
Fixed Value | http://hl7.org/fhir/StructureDefinition/11179-objectClassProperty |
4. Extension.value[x] | |
Definition | Value of extension - must be one of a constrained set of the data types (see Extensibility for a list). |
Control | 10..1 This element is affected by the following invariants: ext-1 |
Binding | For example codes, see DataElementSDCObjectClassFor codes, see (unbound) |
