parentrelationC_ATTRIBUTE that owns this C_OBJECT.
parentoperationParent of this node in a compositional hierarchy.
parent_archetyperelation
parent_archetype_idattribute
Identifier of the specialisation parent of this archetype.
parent_resourcerelationReference to owning resource.
PARTICIPATIONclassModel of a participation of a Party (any Actor or Role) in an activity.
Used to represent any participation of a Party in some activity, which is not
explicitly in the model, e.g. assisting nurse. Can be used to record past or
future participations.
Should not be used in place of more permanent relationships between
demographic entities.
PARTICIPATIONartifact
participationsrelationParties involved in the healthcare event. These would normally include the
physician(s) and often the patient (but not the latter if the clinical session
is a pathology test for example).
PARTY_IDENTIFIEDclassProxy data for an identified party other than the subject of the record, minimally
consisting of human-readable identifier(s), such as name, formal (and possibly
computable) identifiers such as NHS number, and an optional link to external
data. There must be at least one of name, identifier or external_ref present.

Used to describe parties where only identifiers may be known, and there is no
entry at all in the demographic system (or even no demographic system).
Typically for health care providers, e.g. name and provider number of an institution.

Should not be used to include patient identifying information.
PARTY_IDENTIFIEDartifact
PARTY_PROXYclassAbstract concept of a proxy description of a party, including an optional link to
data for this party in a demographic or other identity management system. Sub-
typed into PARTY_IDENTIFIED and PARTY_SELF.
PARTY_PROXYartifact
PARTY_REFclassIdentifier for parties in a demographic or identity service. There are typically a
number of subtypes of the PARTY class, including PERSON, ORGANISATION, etc.
Abstract supertypes are allowed if the referenced object is of a type not known by
the current implementation of this class (in other words, if the demographic model
is changed by the addition of a new PARTY or ACTOR subtypes, valid
PARTY_REFs can still be constructed to them).
PARTY_REFartifact
PARTY_RELATEDclassProxy type for identifying a party and its relationship to the subject of the record.
Use where the relationship between the party and the subject of the record must
be known.
PARTY_RELATEDartifact
PARTY_SELFclassParty proxy representing the subject of the record.
Used to indicate that the party is the owner of the record.
May or may not have external_ref set.

PARTY_SELFartifact
pathoperationPath of this node relative to root of archetype.
pathoperationA string whose format is a function of the scheme. Identifies the location in <scheme>-space of an information entity.
Typical values include hierarchical directory paths for any machine. For example, with scheme = "ftp", path might be
/pub/images/image_01. The strings "." and ".." are reserved for use in the path. Paths may include internet/intranet location identifiers of the form:
sub_domain...domain, e.g. "info.cern.ch"
pathattributeThe path to an instance in question, as an absolute path with respect to
the object found at VERSION.data. An empty path means that
the object referred to by id being specified.
pathattribute
pathattribute
path_existsoperationTrue if the path exists in the data with respect to the current item.
path_of_itemoperationThe path to an item relative to the root of this archetyped structure.
path_specsrelation
path_uniqueoperationTrue if the path corresponds to a single item in the data.
PATHABLEclassThe PATHABLE class defines the pathing capabilities used by nearly all classes in the openEHR reference
model, mostly via inheritance of LOCATABLE. The defining characteristics of PATHABLE objects
are that they can locate child objects using paths, and they know their parent object in a compositional
hierarchy. The parent feature is defined as abstract in the model, and may be implemented in
any way convenient.
PATHABLEartifact
patternattributeRegular expression pattern for proposed instances of String to match.
performerrelationThe id and possibly demographic system link of the party participating in
the activity.
periodoperationThe period of the repetition, computationally derived from the syntax
representation. Extracted from the value' attribute.
periodattributePeriod between samples in this segment if periodic.
physical_pathsoperation
Set of language-independent paths extracted from archetype. Paths obey Xpath-like
syntax and are formed from alternations of C_OBJECT.node_id and
C_ATTRIBUTE.rm_attribute_name values.
pk_fractionattributeNumerator and denominator are integral, and the presentation
method uses a slash, e.g. 1/2 .
pk_integer_fractionattributeNumerator and denominator are integral, and the presentation
method uses a slash, e.g. 1/2 ; if the numerator is greater than the
denominator, e.g. n=3, d=2, the presentation is 1 1/2 .
pk_percentattributeDenominator is 100, numerator is
understood as a percentage value.
pk_ratioattributeRatio type. Numerator and denominator may be any value.
pk_unitaryattributeDenominator must be 1
POINT_EVENTclassDefines a single point event in a series.
POINT_EVENTartifact
preceding_version_uidoperationComputed version of inheritance precursor, derived as item.preceding_version_uid.
preceding_version_uidattributeStored version of inheritance precursor.
preceding_version_uidoperationUnique identifier of the version of which this version is a modification;
Void if this is the first version.
precisionattributeConstraint on the precision of the DV_QUANTITY. A value of -1 means that
precision is unconstrained.
precisionattributePrecision to which the numerator and denominator values of the
proportion are expressed, in terms of number of decimal places. The
value 0 implies an integral quantity. The value -1 implies no limit, i.e.
any number of decimal places.
precisionattribute
previous_versionoperation
Version of predecessor archetype of this archetype, if any.
primitivepackageUltimately any archetype definition will devolve down to leaf node constraints on
instances of primitive types. The primitive package defines the semantics of constraint
on such types.
primitive_class_diag (am)class diagram
primitive_cvclass view
primitive_dvdeployment view
proofattributeProof of attestation.
propertyattributeOptional constraint on units property .
PROPORTION_KINDclassClass of enumeration constants defining types of proportion for the
DV_PROPORTION class.
PROPORTION_KINDartifact
protocolattributeDescription of the method (i.e. how) the information in this entry was
arrived at. For OBSERVATIONs, this is a description of the method or
instrument used. For EVALUATIONs, how the evaluation was arrived at.
For INSTRUCTIONs, how to execute the Instruction. This may take the
form of references to guidelines, including manually followed and
executable; knowledge references such as a paper in Medline; clinical
reasons within a larger care process.
providerattributeOptional identification of provider of the information in this ENTRY,
which might be:
* the patient
* a patient agent, e.g. parent, guardian
* the clinician
* a device or software

Generally only used when the recorder needs to make it explicit. Otherwise,
Composition composer and other participants are assumed.
providerattribute
Optional provider(s) who created, committed,
forwarded or otherwise handled the item.
purposeattributePurpose of the resource.
purposeattribute
Purpose of the mapping e.g. automated data mining , billing , interoperability
