1.0.0 - CI Build
Cross Border Data Exchange IG, published by IEHR-Workgroup. This guide is not an authorized publication; it is the continuous build for version 1.0.0 built by the FHIR (HL7® FHIR® Standard) CI Build. This version is based on the current content of https://github.com/InteropEHRate-project/cross-border-data-exchange/ and changes regularly. See the Directory of published versions

| 0. Period | |
| Definition | A time period defined by a start and end date and optionally time. |
| Short | Time range defined by start and end date/time |
| Comments | 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"). Period is not used for a duration (a measure of elapsed time). See Duration. |
| Control | 0..* This element is affected by the following invariants: ele-1 |
| Is Modifier | false |
| Invariants | ele-1: All FHIR elements must have a @value or children (hasValue() or (children().count() > id.count())) per-1: If present, start SHALL have a lower value than end ( start.hasValue().not() or end.hasValue().not() or (start <= end))per-1: If present, start SHALL have a lower value than end (start.hasValue().not() or end.hasValue().not() or (start <= end)) |
| 2. Period.start | |
| Definition | The start of the period. The boundary is inclusive. |
| Short | Starting time with inclusive boundary |
| Comments | If the low element is missing, the meaning is that the low boundary is not known. |
| Control | 10..1 This element is affected by the following invariants: per-1 |
| Type | dateTime |
| Is Modifier | false |
| 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())) |

| 2. Period.id | |
| Definition | Unique id for the element within a resource (for internal references). This may be any string value that does not contain spaces. |
| Short | Unique id for inter-element referencing |
| Control | 0..1 |
| Type | string |
| Is Modifier | false |
| XML Format | In the XML format, this property is represented as an attribute. |
| Summary | false |
| 4. Period.extension | |
| Definition | 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. |
| 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. |
| Control | 0..* |
| Type | Extension |
| Is Modifier | false |
| Summary | false |
| Alternate Names | extensions, user content |
| Invariants | 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 Period.extension. The slices are unordered and Open, and can be differentiated using the following discriminators: |
| 6. Period.start | |
| Definition | The start of the period. The boundary is inclusive. |
| Short | Starting time with inclusive boundary |
| Comments | If the low element is missing, the meaning is that the low boundary is not known. |
| Control | 1..1 This element is affected by the following invariants: per-1 |
| Type | dateTime |
| Is Modifier | false |
| 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())) |
| 8. Period.end | |
| Definition | The end of the period. If the end of the period is missing, it means no end was known or planned at the time the instance was created. The start may be in the past, and the end date in the future, which means that period is expected/planned to end at that time. |
| Short | End time with inclusive boundary, if not ongoing |
| Comments | The high value includes any matching date/time. i.e. 2012-02-03T10:00:00 is in a period that has an end value of 2012-02-03. |
| Control | 0..1 This element is affected by the following invariants: per-1 |
| Type | dateTime |
| Is Modifier | false |
| Primitive Value | This primitive element may be present, or absent, or replaced by an extension |
| Summary | true |
| Meaning if Missing | If the end of the period is missing, it means that the period is ongoing |
| Invariants | ele-1: All FHIR elements must have a @value or children (hasValue() or (children().count() > id.count())) |
