Demographics and administrative information about a person independent of a specific health-related context.
The Person resource does justice to person registries that keep track of persons regardless of their role. The Person resource is also a primary resource to point to for people acting in a particular role such as SubjectofCare, Practitioner, and Agent. Very few attributes are specific to any role and so Person is kept lean. Most attributes are expected to be tied to the role the Person plays rather than the Person himself. Examples of that are Guardian (SubjectofCare), ContactParty (SubjectOfCare, Practitioner), and multipleBirthInd (SubjectofCare).
If the resource is contained in another resource, it SHALL NOT contain nested Resources
not(parent::f:contained and f:contained)
If the resource is contained in another resource, it SHALL be referred to from elsewhere in the resource or SHALL refer to the containing resource
contained.where((('#'+id in (%resource.descendants().reference | %resource.descendants().as(canonical) | %resource.descendants().as(uri) | %resource.descendants().as(url))) or descendants().where(reference = '#').exists() or descendants().where(as(canonical) = '#').exists() or descendants().where(as(canonical) = '#').exists()).not()).trace('unmatched', id).empty()
not(exists(for $id in f:contained/*/f:id/@value return $contained[not(parent::*/descendant::f:reference/@value=concat('#', $contained/*/id/@value) or descendant::f:reference[@value='#'])]))
If a resource is contained in another resource, it SHALL NOT have a meta.versionId or a meta.lastUpdated
contained.meta.versionId.empty() and contained.meta.lastUpdated.empty()
not(exists(f:contained/*/f:meta/f:versionId)) and not(exists(f:contained/*/f:meta/f:lastUpdated))
If a resource is contained in another resource, it SHALL NOT have a security label
When a resource has no narrative, only systems that fully understand the data can display the resource to a human safely. Including a human readable representation in the resource makes for a much more robust eco-system and cheaper handling of resources by intermediary systems. Some ecosystems restrict distribution of resources to only those systems that do fully understand the resources, and as a consequence implementers may believe that the narrative is superfluous. However experience shows that such eco-systems often open up to new participants over time.
A resource should have narrative for robust management
Person(classCode="PSN" and determinerCode="INST" and quantity="1")
The logical id of the resource, as used in the URL for the resource. Once assigned, this value never changes.
The only time that a resource does not have an id is when it is being submitted to the server using a create operation.
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.
All FHIR elements must have a @value or children
hasValue() or (children().count() > id.count())
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.
Must have either extensions or value[x], not both
exists(f:extension)!=exists(f:*[starts-with(local-name(.), "value")])
The version specific identifier, as it appears in the version portion of the URL. This value changes when the resource is created, updated, or deleted.
The server assigns this value, and ignores what the client specifies, except in the case that the server is imposing version integrity on updates/deletes.
When the resource last changed - e.g. when the version changed.
This value is always populated except when the resource is first being created. The server / resource manager sets this value; what a client provides is irrelevant. This is equivalent to the HTTP Last-Modified and SHOULD have the same value on a [read](http://hl7.org/fhir/R4/http.html#read) interaction.
Identifies where the resource comes from
A uri that identifies the source system of the resource. This provides a minimal amount of [Provenance](http://hl7.org/fhir/R4/provenance.html#) information that can be used to track or differentiate the source of information in the resource. The source may identify another FHIR server, document, message, database, etc.
In the provenance resource, this corresponds to Provenance.entity.what[x]. The exact use of the source (and the implied Provenance.entity.role) is left to implementer discretion. Only one nominated source is allowed; for additional provenance details, a full Provenance resource should be used. This element can be used to indicate where the current master source of a resource that has a canonical URL if the resource is no longer hosted at the canonical URL.
Profiles this resource claims to conform to
A list of profiles (references to [StructureDefinition](http://hl7.org/fhir/R4/structuredefinition.html#) resources) that this resource claims to conform to. The URL is a reference to [StructureDefinition.url](http://hl7.org/fhir/R4/structuredefinition-definitions.html#StructureDefinition.url).
It is up to the server and/or other infrastructure of policy to determine whether/how these claims are verified and/or updated over time. The list of profile URLs is a set.
Security Labels applied to this resource
Security labels applied to this resource. These tags connect specific resources to the overall security policy and infrastructure.
The security labels can be updated without changing the stated version of the resource. The list of security labels is a set. Uniqueness is based the system/code, and version and display are ignored.
Security Labels from the Healthcare Privacy and Security Classification System.
Tags applied to this resource. Tags are intended to be used to identify and relate resources to process and workflow, and applications are not required to consider the tags when interpreting the meaning of a resource.
The tags can be updated without changing the stated version of the resource. The list of tags is a set. Uniqueness is based the system/code, and version and display are ignored.
Codes that represent various types of tags, commonly workflow-related; e.g. "Needs review by Dr. Jones".
A set of rules under which this content was created
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.
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 it's narrative along with other profiles, value sets, etc.
This element is labeled as a modifier because the implicit rules may provide additional knowledge about the resource that modifies it's meaning or interpretation
The base language in which the resource is written.
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).
Text summary of the resource, for human interpretation
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 resources do not have 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.
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.
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.
exists(f:extension)!=exists(f:*[starts-with(local-name(.), 'value')])
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. Modifier extensions SHALL NOT change the meaning of any elements on Resource or DomainResource (including cannot change the meaning of modifierExtension itself).
Modifier extensions allow for extensions that *cannot* be safely ignored to be clearly distinguished from the vast majority of extensions which can be safely ignored. This promotes interoperability by eliminating the need for implementers to prohibit the presence of extensions. For further information, see the [definition of modifier extensions](http://hl7.org/fhir/R4/extensibility.html#modifierExtension).
Modifier extensions are expected to modify the meaning or interpretation of the resource that contains them
Identifier for a person within a particular scope.
People are known by a variety of ids. Some institutions maintain several, and most collect identifiers for exchange with other organizations concerning the person. Examples are national person identifier and local identifier.
usual | official | temp | secondary | old (If known)
Applications can assume that an identifier is permanent unless it explicitly says that it is temporary.
Allows the appropriate identifier for a particular context of use to be selected from among a set of identifiers.
This is labeled as "Is Modifier" because applications should not mistake a temporary id for a permanent one.
Identifies the purpose for this identifier, if known .
A coded type for the identifier that can be used to determine which identifier to use for a specific purpose.
This element deals only with general categories of identifiers. It SHOULD not be used for codes that correspond 1..1 with the Identifier.system. Some identifiers may fall into multiple categories due to common usage. Where the system is known, a type is unnecessary because the type is always part of the system definition. However systems often need to handle identifiers where the system is not known. There is not a 1:1 relationship between type and system, since many different systems have the same type.
Allows users to make use of identifiers when the identifier system is not known.
A coded type for an identifier that can be used to determine which identifier to use for a specific purpose.
Establishes the namespace for the value - that is, a URL that describes a set values that are unique.
Identifier.system is always case sensitive.
There are many sets of identifiers. To perform matching of two identifiers, we need to know what set we're dealing with. The system identifies a particular set of unique identifiers.
The portion of the identifier typically relevant to the user and which is unique within the context of the system.
If the value is a full URI, then the system SHALL be urn:ietf:rfc:3986. The value's primary purpose is computational mapping. As a result, it may be normalized for comparison purposes (e.g. removing non-significant whitespace, dashes, etc.) A value formatted for human display can be conveyed using the [Rendered Value extension](http://hl7.org/fhir/R4/extension-rendered-value.html). Identifier.value is to be treated as case sensitive unless knowledge of the Identifier.system allows the processer to be confident that non-case-sensitive processing is safe.
II.extension or II.root if system indicates OID or GUID (Or Role.id.extension or root)
Time period when id is/was valid for use
Time period during which identifier is/was valid for use.
Role.effectiveTime or implied by context
Organization that issued id (may be just text)
Organization that issued/manages the identifier.
The Identifier.assigner may omit the .reference element and only contain a .display element reflecting the name or other textual information about the assigning organization.
II.assigningAuthorityName but note that this is an improper use by the definition of the field. Also Role.scoper
Person may have multiple names with different uses or applicable periods.
Need to be able to track the person by multiple names. Examples are your official name and a partner name.
usual | official | temp | nickname | anonymous | old | maiden
Applications can assume that a name is current unless it explicitly says that it is temporary or old.
Allows the appropriate name for a particular context of use to be selected from among a set of names.
This is labeled as "Is Modifier" because applications should not mistake a temporary or old name etc.for a current/permanent one
XPN.7, but often indicated by which field contains the name
Specifies the entire name as it should be displayed e.g. on an application UI. This may be provided instead of or as well as the specific parts.
Can provide both a text representation and parts. Applications updating a name SHALL ensure that when both text and parts are present, no content is included in the text that isn't found in a part.
The part of a name that links to the genealogy. In some cultures (e.g. Eritrea) the family name of a son is the first name of his father.
Family Name may be decomposed into specific parts using extensions (de, nl, es related cultures).
Given names (not always 'first'). Includes middle names
If only initials are recorded, they may be used in place of the full name parts. Initials may be separated into multiple given names but often aren't due to paractical limitations. This element is not called "first name" since given names do not always come first.
Given Names appear in the correct order for presenting the name
Part of the name that is acquired as a title due to academic, legal, employment or nobility status, etc. and that appears at the start of the name.
Prefixes appear in the correct order for presenting the name
unique id for the element within a resource (for internal references)
LS | AC | NB | PR | HON | BR | AD | SP | MID | CL | IN | VV
A set of codes each of which specifies a certain subcategory of the name part in addition to the main name part type.
Used to indicate additional information about the name part and how it should be used.
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/R5/extensibility.html) for a list).
Part of the name that is acquired as a title due to academic, legal, employment or nobility status, etc. and that appears at the end of the name.
Suffixes appear in the correct order for presenting the name
Indicates the period of time when this name was valid for the named person.
Allows names to be placed in historical context.
A contact detail for the person, e.g. a telephone number or an email address.
Person may have multiple ways to be contacted with different uses or applicable periods. May need to have options for contacting the person urgently and also to help with identification.
People have (primary) ways to contact them in some way such as phone, email.
phone | fax | email | pager | url | sms | other
Telecommunications form for contact point - what communications system is required to make use of the contact.
Telecommunications form for contact point.
The actual contact point details, in a form that is meaningful to the designated communication system (i.e. phone number or email address).
Additional text data such as phone extension numbers, or notes about use of the contact are sometimes included in the value.
Need to support legacy numbers that are not in a tightly controlled format.
home | work | temp | old | mobile - purpose of this contact point
Identifies the purpose for the contact point.
Applications can assume that a contact is current unless it explicitly says that it is temporary or old.
Need to track the way a person uses this contact, so a user can choose which is appropriate for their purpose.
This is labeled as "Is Modifier" because applications should not mistake a temporary or old contact etc.for a current/permanent one
Specify preferred order of use (1 = highest)
Specifies a preferred order in which to use a set of contacts. ContactPoints with lower rank values are more preferred than those with higher rank values.
Note that rank does not necessarily follow the order in which the contacts are represented in the instance.
Time period when the contact point was/is in use
Time period when the contact point was/is in use.
The gender might not match the biological sex as determined by genetics, or the individual's preferred identification. Note that for both humans and particularly animals, there are other legitimate possibilities than M and F, though a clear majority of systems and contexts only support M and F.
Needed for identification of the person, in combination with (at least) name and birth date. Gender of person drives many clinical processes.
The gender of a person used for administrative purposes.
player[classCode=PSN|ANM and determinerCode=INSTANCE]/administrativeGender
At least an estimated year should be provided as a guess if the real DOB is unknown.
Age of person drives many clinical processes, and is often used in performing identification of the person. Times are not included so as to not confuse things with potential timezone issues.
Person may have multiple addresses with different uses or applicable periods.
May need to keep track of person's addresses for contacting, billing or reporting requirements and also to help with identification.
home | work | temp | old | billing - purpose of this address
Applications can assume that an address is current unless it explicitly says that it is temporary or old.
Allows an appropriate address to be chosen from a list of many.
This is labeled as "Is Modifier" because applications should not mistake a temporary or old address etc.for a current/permanent one
Distinguishes between physical addresses (those you can visit) and mailing addresses (e.g. PO Boxes and care-of addresses). Most addresses are both.
The definition of Address states that "address is intended to describe postal addresses, not physical locations". However, many applications track whether an address has a dual purpose of being a location that can be visited as well as being a valid delivery destination, and Postal addresses are often used as proxies for physical locations (also see the [Location](http://hl7.org/fhir/R4/location.html#) resource).
The type of an address (physical / postal).
Specifies the entire address as it should be displayed e.g. on a postal label. This may be provided instead of or as well as the specific parts.
Can provide both a text representation and parts. Applications updating an address SHALL ensure that when both text and parts are present, no content is included in the text that isn't found in a part.
XAD.1 + XAD.2 + XAD.3 + XAD.4 + XAD.5 + XAD.6
Street name, number, direction & P.O. Box etc.
This component contains the house number, apartment number, street name, street direction, P.O. Box number, delivery hints, and similar address information.
The order in which lines should appear in an address label
XAD.1 + XAD.2 (note: XAD.1 and XAD.2 have different meanings for a company address than for a person address)
The name of the city, town, suburb, village or other community or delivery center.
The name of the administrative area (county).
District is sometimes known as county, but in some regions 'county' is used in place of city (municipality), so county name should be conveyed in city instead.
Sub-unit of a country with limited sovereignty in a federally organized country. A code may be used if codes are in common use (e.g. US 2 letter state codes).
A postal code designating a region defined by the postal service.
Country (e.g. can be ISO 3166 2 or 3 letter code)
Country - a nation as commonly understood or generally accepted.
ISO 3166 3 letter codes can be used in place of a human readable country name.
Allows addresses to be placed in historical context.
An image that can be displayed as a thumbnail of the person to enhance the identification of the individual.

repräsentiert hier die Domäne, zur der der MPI-Eintrag gehört.
Need to know who recognizes this person record, manages and updates it.
Literal reference, Relative, internal or absolute URL
A reference to a location at which the other resource is found. The reference may be a relative reference, in which case it is relative to the service base URL, or an absolute URL that resolves to the location where the resource is found. The reference may be version specific or not. If the reference is not to a FHIR RESTful server, then it should be assumed to be version specific. Internal fragment references (start with '#') refer to contained resources.
Using absolute URLs provides a stable scalable approach suitable for a cloud/web context, while using relative/logical references provides a flexible approach suitable for use when trading across closed eco-system boundaries. Absolute URLs do not need to point to a FHIR RESTful server, though this is the preferred approach. If the URL conforms to the structure "/[type]/[id]" then it should be assumed that the reference is to a FHIR RESTful server.
Type the reference refers to (e.g. "Patient")
The expected type of the target of the reference. If both Reference.type and Reference.reference are populated and Reference.reference is a FHIR URL, both SHALL be consistent. The type is the Canonical URL of Resource Definition that is the type this reference refers to. References are URLs that are relative to http://hl7.org/fhir/StructureDefinition/ e.g. "Patient" is a reference to http://hl7.org/fhir/StructureDefinition/Patient. Absolute URLs are only allowed for logical models (and can only be used in references in logical models, not resources).
This element is used to indicate the type of the target of the reference. This may be used which ever of the other elements are populated (or not). In some cases, the type of the target may be determined by inspection of the reference (e.g. a RESTful URL) or by resolving the target of the reference; if both the type and a reference is provided, the reference SHALL resolve to a resource of the same type as that specified.
Aa resource (or, for logical models, the URI of the logical model).
Logical reference, when literal reference is not known
An identifier for the target resource. This is used when there is no way to reference the other resource directly, either because the entity it represents is not available through a FHIR server, or because there is no way for the author of the resource to convert a known identifier to an actual location. There is no requirement that a Reference.identifier point to something that is actually exposed as a FHIR instance, but it SHALL point to a business concept that would be expected to be exposed as a FHIR instance, and that instance would need to be of a FHIR resource type allowed by the reference.
When an identifier is provided in place of a reference, any system processing the reference will only be able to resolve the identifier to a reference if it understands the business context in which the identifier is used. Sometimes this is global (e.g. a national identifier) but often it is not. For this reason, none of the useful mechanisms described for working with references (e.g. chaining, includes) are possible, nor should servers be expected to be able resolve the reference. Servers may accept an identifier based reference untouched, resolve it, and/or reject it - see CapabilityStatement.rest.resource.referencePolicy. When both an identifier and a literal reference are provided, the literal reference is preferred. Applications processing the resource are allowed - but not required - to check that the identifier matches the literal reference Applications converting a logical reference to a literal reference may choose to leave the logical reference present, or remove it. Reference is intended to point to a structure that can potentially be expressed as a FHIR resource, though there is no need for it to exist as an actual FHIR resource instance - except in as much as an application wishes to actual find the target of the reference. The content referred to be the identifier must meet the logical constraints implied by any limitations on what resource types are permitted for the reference. For example, it would not be legitimate to send the identifier for a drug prescription if the type were Reference(Observation|DiagnosticReport). One of the use-cases for Reference.identifier is the situation where no FHIR representation exists (where the type is Reference (Any).
Plain text narrative that identifies the resource in addition to the resource reference.
This is generally not the same as the Resource.text of the referenced resource. The purpose is to identify what's being referenced, not to fully describe it.
Whether this person's record is in active use.
Need to be able to mark a person record as not to be used because it was created in error.
This element is labelled as a modifier because it is a status element that can indicate that a record should not be treated as valid
Link to a resource that concerns the same actual person
Link to a resource that concerns the same actual person.
Extensions that cannot be ignored even if unrecognized
May be used to represent additional information that is not part of the basic definition of the element and that modifies the understanding of the element in which it is contained 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 can 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).
Modifier extensions are expected to modify the meaning or interpretation of the element that contains them
The resource to which this actual person is associated
The resource to which this actual person is associated.
Level of assurance that this link is associated with the target resource.
