Declares the DateLastUpdated and Frequency arguments to be used by the Data Date Roller for maintaining/rolling test data dates to keep them from going stale.
The DateLastUpdated and Frequency arguments for the data date roller.
All FHIR elements must have a @value or children
hasValue() or (children().count() > id.count())
Must have either extensions or value[x], not both
exists(f:extension)!=exists(f:*[starts-with(local-name(.), 'value')])
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 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.
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.
exists(f:extension)!=exists(f:*[starts-with(local-name(.), "value")])
Date that datetime-valued elements were last updated
The date that datetime-valued elements of the resource were last updated.
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/R4/extensibility.html) for a list).
How often and by what offset the dateTime values should be adjusted forward
Frequency is used to specify how often the dateTime-valued elements within the resource should have their values updated and also, the offset or duration by which they should be adjusted forward. The determination for when to update the values and by how much should be made by comparing the current dateTime to the value of dateLastUpdated. If the duration specified by frequency has elapsed since the dateLastUpdated value, then the dateTime-valued elements within the resource should all be updated - their value incremented by the duration specified in the frequency value.
