Once assigned, this value never changes.                                                                                                                      |
| meta               |          | [Meta](/content/docs/api/fhir/datatypes/meta/index.html) | Details<br>The metadata about the resource. This is content that is maintained by the infrastructure. Changes to the content might not always be associated with version changes to the resource.                                                                              |

Often, this is a reference to an implementation guide that defines the special rules along with other profiles etc.       |
| language           |          | code                                                      | Details<br>The base language in which the resource is written.                                                                                                                                                                                                                  |
| text               |          | [Narrative](/content/docs/api/fhir/datatypes/narrative/index.html) | Text summary of the resource, for human interpretation<br>Details<br>A human-readable narrative that contains a summary of the resource and can be used to represent the content of the resource to a human. The narrative need not encode all the structured data, but is required to contain sufficient detail to make it "clinically safe" for a human to just read the narrative. Resource definitions may define what content should be represented in the narrative to ensure clinical safety. |
| contained          |          | Resource[]                                                | Details<br>These resources do not have an independent existence apart from the resource that contains them - they cannot be identified independently, and nor can they have their own independent transaction scope.                                                            |
| extension          |          | [Extension](/content/docs/api/fhir/datatypes/extension/index.html)[] | Additional content defined by implementations<br>Details<br>May be used to represent additional information that is not part of the basic definition of the resource. 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.            |
| modifierExtension   |          | [Extension](/content/docs/api/fhir/datatypes/extension/index.html)[] | Extensions that cannot be ignored<br>Details<br>May be used to represent additional information that is not part of the basic definition of the resource and that modifies the understanding of the element that contains it and/or the understanding of the containing element's descendants. Usually modifier elements provide negation or qualification. 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 is allowed to define an extension, there is a set of requirements that SHALL be met as part of the definition of the extension. Applications processing a resource are required to check for modifier extensions.<br>Modifier extensions SHALL NOT change the meaning of any elements on Resource or DomainResource (including cannot change the meaning of modifierExtension itself). |
