Definitions for the oid data type profile.
Guidance on how to interpret the contents of this table can be foundhere
| 0. string | |
| Definition | A sequence of Unicode characters |
| Short | Primitive Type string |
| Comments | Note that FHIR strings SHALL NOT exceed 1,048,576 (1024*1024) characters in size |
| Control | 0..* |
| Is Modifier | false |
| XML Format | In the XML format, this property has the namespace urn:hl7-org:v3. |
| Summary | false |
| Invariants | ele-1: All FHIR elements must have a @value or children (hasValue() or (children().count() > id.count())) oid-pattern: Must conform to OID (#.#.#), UUID (32 hexadecimal digits separated by hyphens), or RUID (a letter followed by any combination of letters, numbers or hyphens) ( matches('^[0-2](\\.(0|[1-9][0-9]*))+$')) |
| 2. string.id | |
| Definition | unique id for the element within a resource (for internal references) Unique id for the element within a resource (for internal references). This may be any string value that does not contain spaces. |
| Short | xml:id (or equivalent in JSON)Unique id for inter-element referencing |
| Control | 0..01 This element is affected by the following invariants: ele-1 |
| Type | string |
| Is Modifier | false |
| XML Format | In the XML format, this property is represented as an attribute. |
| Summary | false |
| 4. string.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. |
| Short | ExtensionAdditional 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..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()) |
