Guidance on how to interpret the contents of this table can be found here
0. DocumentReference | |
Definition | A reference to a document of any kind for any purpose. While the term “document” implies a more narrow focus, for this resource this "document" encompasses any serialized object with a mime-type, it includes formal patient-centric documents (CDA), clinical notes, scanned paper, non-patient specific documents like policy text, as well as a photo, video, or audio recording acquired or used in healthcare. The DocumentReference resource provides metadata about the document so that the document can be discovered and managed. The actual content may be inline base64 encoded data or provided by direct reference. |
Short | A reference to a document |
Comments | Usually, this is used for documents other than those defined by FHIR. |

2. DocumentReference.implicitRules | |
Definition | A reference to a set of rules that were followed when the resource was constructed, and which must be understood when processing the content. Often, this is a reference to an implementation guide that defines the special rules along with other profiles etc. |
Short | A set of rules under which this content was created |
Comments | Asserting this rule set restricts the content to be only understood by a limited set of trading partners. This inherently limits the usefulness of the data in the long term. However, the existing health eco-system is highly fractured, and not yet ready to define, collect, and exchange data in a generally computable sense. Wherever possible, implementers and/or specification writers should avoid using this element. Often, when used, the URL is a reference to an implementation guide that defines these special rules as part of its narrative along with other profiles, value sets, etc. |
Control | 0..1 |

Invariants | ele-1: All FHIR elements must have a @value or children (hasValue() or (children().count() > id.count())) |
4. DocumentReference.contained | |
Definition | These resources do not have an independent existence apart from the resource that contains them - they cannot be identified independently, nor can they have their own independent transaction scope. This is allowed to be a Parameters resource if and only if it is referenced by a resource that provides context/meaning. |
Short | Contained, inline Resources |
Comments | This should never be done when the content can be identified properly, as once identification is lost, it is extremely difficult (and context dependent) to restore it again. Contained resources may have profiles and tags in their meta elements, but SHALL NOT have security labels. |

6. DocumentReference.modifierExtension | |
Definition | 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 managable, 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. Modifier extensions SHALL NOT change the meaning of any elements on Resource or DomainResource (including cannot change the meaning of modifierExtension itself). |
Short | Extensions that cannot be ignored |
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. |

8. DocumentReference.identifier | |
Definition | Other business identifiers associated with the document, including version independent identifiers. |
Short | Business identifiers for the document |
Comments | The structure and format of this identifier would be consistent with the specification corresponding to the format of the document. (e.g. for a DICOM standard document, a 64-character numeric UID; for an HL7 CDA format, the CDA Document Id root and extension). |
Note | This is a business identifier, not a resource identifier (see discussion) |

2. DocumentReference.id | |
Definition | The logical id of the resource, as used in the URL for the resource. Once assigned, this value never changes. |
Short | Logical id of this artifact |

Comments | Language is provided to support indexing and accessibility (typically, services such as text to speech use the language tag). The html language tag in the narrative applies to the narrative. The language tag on the resource may be used to specify the language of other presentations generated from the data in the resource. Not all the content has to be in the base language. The Resource.language should not be assumed to apply to the narrative automatically. If a language is specified, it should it also be specified on the div element in the html (see rules in HTML5 for information about the relationship between xml:lang and the html lang attribute). |

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. |
Short | Text summary of the resource, for human interpretation |
Comments | Contained resources do not have a narrative. Resources that are not contained SHOULD have a narrative. In some cases, a resource may only have text with little or no additional discrete data (as long as all minOccurs=1 elements are satisfied). This may be necessary for data from legacy systems where information is captured as a "text blob" or where text is additionally entered raw or narrated and encoded information is added later. |

Note that DocumentReference.meta.security contains the security labels of the data elements in DocumentReference, while DocumentReference.securityLabel contains the security labels for the document the reference refers to. The distinction recognizes that the document may contain sensitive information, while the DocumentReference is metadata about the document and thus might not be as sensitive as the document. For example: a psychotherapy episode may contain highly sensitive information, while the metadata may simply indicate that some episode happened. |
Short | Document security-tags |
Comments | The confidentiality codes can carry multiple vocabulary items. HL7 has developed an understanding of security and privacy tags that might be desirable in a Document Sharing environment, called HL7 Healthcare Privacy and Security Classification System (HCS). The following specification is recommended but not mandated, as the vocabulary bindings are an administrative domain responsibility. The use of this method is up to the policy domain such as the XDS Affinity Domain or other Trust Domain where all parties including sender and recipients are trusted to appropriately tag and enforce. In the HL7 Healthcare Privacy and Security Classification (HCS) there are code systems specific to Confidentiality, Sensitivity, Integrity, and Handling Caveats. Some values would come from a local vocabulary as they are related to workflow roles and special projects. |
