The only time that a resource does not have an id is when it is being submitted to the server using a create operation.

  hasValue() or (children().count() > id.count())

• rim:n/a
• rim:N/A

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.

• ele-1:All FHIR elements must have a @value or children
  hasValue() or (children().count() > id.count())

• rim:n/a

A human language.

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).

• ele-1:All FHIR elements must have a @value or children
  hasValue() or (children().count() > id.count())

• rim:n/a

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.

• ele-1:All FHIR elements must have a @value or children
  hasValue() or (children().count() > id.count())

• rim:n/a
• rim:N/A
• rim:Act.text?

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.

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.

• 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()

• rim:n/a
• rim:N/A

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.

Type of event.

This identifies the performed function. For "Execute" Event Action Code audit records, this identifies the application function performed.

Codes may be defined very casually in enumerations or code lists, up to very formal definitions such as SNOMED CT - see the HL7 v3 Core Principles for more information.

Indicator for type of action performed during the event that generated the event.

This broadly indicates what kind of action was done on the AuditEvent.entity by the AuditEvent.agent.

Note that FHIR strings SHALL NOT exceed 1MB in size

• fhirprovenance:Provenance.occurred[x]

This ties an event to a specific date and time. Security audits typically require a consistent time base (e.g. UTC), to eliminate time-zone issues arising from geographical distribution.

In a distributed system, some sort of common time base (e.g. an NTP [RFC1305] server) is a good implementation tactic.

• fhirprovenance:Provenance.recorded

Indicates whether the event succeeded or failed.

In some cases a "success" may be partial, for example, an incomplete or interrupted transfer of a radiological study. For the purpose of establishing accountability, these distinctions are not relevant.

An agent can be a person, an organization, software, device, or other actors that may be ascribed responsibility.

Several agents may be associated (i.e. have some responsibility for an activity) with an event or activity.

For example, an activity may be initiated by one user for other users or involve more than one user. However, only one user may be the initiator/requestor for the activity.

The Participation type of the agent to the event.

Not all terminology uses fit this general pattern. In some cases, models should not use CodeableConcept and use Coding directly and provide their own structure for managing text, codings, translations and the relationship between elements and pre- and post-coordination.

• dicom:RoleIdCode
• w3c.prov:Agent.Attribution
• fhirprovenance:Provenance.agent.type

What security role enabled the agent to participate in the event.

This value ties an audited event to a user's role(s). It is an optional value that might be used to group events for analysis by user functional role categories.

Should be roles relevant to the event. Should not be an exhaustive list of roles.

• fhirprovenance:Provenance.agent.role

This field ties an audit event to a specific resource or identifier.

Where a User ID is available it will go into who.identifier.

• ele-1:All FHIR elements must have a @value or children
  hasValue() or (children().count() > id.count())
• ref-1:SHALL have a contained resource if a local reference is provided

• workflow:Event.performer.actor
• w5:FiveWs.who
• rim:.id
• dicom:UserId
• w3c.prov:Agent.Identity
• fhirprovenance:Provenance.agent.who

In some situations, a human user may authenticate with one identity but, to access a specific application system, may use a synonymous identify. For example, some "single sign on" implementations will do this. The alternative identifier would then be the original identify used for authentication, and the User ID is the one known to and used by the application.

Note that FHIR strings SHALL NOT exceed 1MB in size

• ele-1:All FHIR elements must have a @value or children
  hasValue() or (children().count() > id.count())

• rim:n/a
• w5:FiveWs.who
• rim:.name
• dicom:UserName
• w3c.prov:Agent.Identity

This value is used to distinguish between requestor-users and recipient-users. For example, one person may initiate a report-output to be sent to another user.

There can only be one initiator. If the initiator is not clear, then do not choose any one agent as the initiator.

• dicom:UserIsRequestor

References SHALL be a reference to an actual FHIR resource, and SHALL be resolveable (allowing for access control, temporary unavailability, etc.). Resolution can be either by retrieval from the URL, or, where applicable by resource type, by treating an absolute reference as a canonical URL and looking it up in a local registry/repository.

May be natural or man-made. The geographic position of a place might or might not be constant.
• w3c.prov:Activity.location
• fhirprovenance:Provenance.location

This value is used retrospectively to determine the authorization policies.

For example: Where an OAuth token authorizes, the unique identifier from the OAuth token is placed into the policy element Where a policy engine (e.g. XACML) holds policy logic, the unique policy identifier is placed into the policy element.

Used when the event is about exporting/importing onto media.

Usually, this is used instead of specifying a network address. This field is not used for Media Id (i.e. the serial number of a CD).

Codes may be defined very casually in enumerations or code lists, up to very formal definitions such as SNOMED CT - see the HL7 v3 Core Principles for more information.

• w3c.prov:Agent.Activity

The event is reported by one source.

Since multi-tier, distributed, or composite applications make source identification ambiguous, this collection of fields may repeat for each application or process actively involved in the event. For example, multiple value-sets can identify participating web servers, application processes, and database server threads in an n-tier distributed application. Passive event participants (e.g. low-level network transports) need not be identified.

Codes may be defined very casually in enumerations or code lists, up to very formal definitions such as SNOMED CT - see the HL7 v3 Core Principles for more information.

• ele-1:All FHIR elements must have a @value or children
  hasValue() or (children().count() > id.count())

• rim:n/a
• v2:CE/CNE/CWE subset one of the sets of component 1-3 or 4-6
• rim:CV
• orim:fhir:Coding rdfs:subClassOf dt:CDCoding
• w5:FiveWs.context
• rim:role.code (not sure what this would mean for an Act)
• dicom:ParticipantObjectTypeCodeRole
• w3c.prov:Entity.role

Identifier for the data life-cycle stage for the entity.

Institutional policies for privacy and security may optionally fall under different accountability rules based on data life cycle. This provides a differentiating value for those cases.

This can be used to provide an audit trail for data, over time, as it passes through the system.

Security Labels from the Healthcare Privacy and Security Classification System.

This field identifies the security labels for a specific instance of an object, such as a patient, to detect/track privacy and security issues.

Copied from entity meta security tags.

Use only where entity can't be identified with an identifier.

This field may be used in a query/report to identify audit events for a specific person. For example, where multiple synonymous entity identifiers (patient number, medical record number, encounter number, etc.) have been used.

For query events, it may be necessary to capture the actual query input to the query process in order to identify the specific event. Because of differences among query implementations and data encoding for them, this is a base 64 encoded data blob. It may be subsequently decoded or interpreted by downstream audit analysis processing.

The meaning and secondary-encoding of the content of base64 encoded blob is specific to the AuditEvent.type, AuditEvent.subtype, AuditEvent.entity.type, and AuditEvent.entity.role. The base64 is a general-use and safe container for event specific data blobs regardless of the encoding used by the transaction being recorded. An AuditEvent consuming application must understand the event it is consuming and the formats used by the event. For example, if auditing an Oracle network database access, the Oracle formats must be understood as they will be simply encoded in the base64binary blob.

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.

• 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()

• rim:n/a
• rim:N/A

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.

Should not duplicate the entity value unless absolutely necessary.

The value can be string when known to be a string, else base64 encoding should be used to protect binary or undefined content. The meaning and secondary-encoding of the content of base64 encoded blob is specific to the AuditEvent.type, AuditEvent.subtype, AuditEvent.entity.type, and AuditEvent.entity.role.
