NameKindDescription
languageattributeMandatory indicator of the localised language in which this Composition
is written. Coded from openEHR Code Set languages . The language of an
Entry if different from the Composition is indicated in ENTRY.language.
languageattributeOptional indicator of the localised language in which the data is written, if relevant.
Coded from openEHR Code Set languages.
languagerelationOptional indicator of the localised language in which the value is written.
Coded from openEHR Code Set languages . Only used when either the text object is
in a different language from the enclosing ENTRY, or else the text object is
being used outside of an ENTRY or other enclosing structure which indicates the
language.
languageattributeMandatory indicator of the localised language in which this Entry is written.
Coded from openEHR Code Set languages .
languageattributeThe localised language in which the items in this description item are written.
Coded from openEHR Code Set languages .
languageattributeLanguage of the translation.
languages_availableoperationTotal list of languages available in this resource, derived from original_language
and translations.
latest_trunk_versionoperationReturn the most recently added trunk version.
latest_versionoperationReturn the most recently added version (i.e. on trunk or any branch).
left_operandrelation
LFattributeline feed character
lifecycle_stateoperationLifecycle state of the content item in wrapped ORIGINAL_VERSION, derived as
item.lifecycle_state.
lifecycle_stateattributeLifecycle state of the content item in this version.
lifecycle_stateoperationLifecycle state of this version; coded by openEHR vocabulary
version lifecycle state .
lifecycle_statusattributeLifecycle state of the resource, typically including states such as: initial,
submitted, experimental, awaiting_approval, approved, superseded, obsolete.
limitsoperationLimits of the ordinal enumeration, to allow comparison of an ordinal
value to its limits.
LINKclassThe LINK type defines a logical relationship between two items, such as two
ENTRYs or an ENTRY and a COMPOSITION. Links can be used across composi-
tions, and across EHRs. Links can potentially be used between interior (i.e. non
archetype root) nodes, although this probably should be prevented in archetypes.
Multiple LINKs can be attached to the root object of any archetyped structure to
give the effect of a 1->N link.

1:1 and 1:N relationships between archetyped content elements (e.g. ENTRYs)
can be expressed by using one, or more than one, respectively, DV_LINKs.
Chains of links can be used to see problem threads or other logical groupings of
items.

Links should be between archetyped structures only, i.e. between objects representing
complete domain concepts because relationships between sub-elements of whole
concepts are not necessarily meaningful, and may be downright confusing. Sensible
links only exist between whole ENTRYs, SECTIONs, COMPOSITIONs and so on.
LINKartifact
linksrelationLinks to other archetyped structures (data whose root object inherits from
ARCHETYPED, such as ENTRY, SECTION and so on). Links may be to
structures in other compositions.
listrelation
Set of allowed DV_ORDINAL values.
listrelationList of value/units pairs.
listattributeSet of Integers specifying constraint.
listattributeSet of Reals specifying constraint .
listattributeSet of Strings specifying constraint.
list_openattributeTrue if the list is being used to specify the constraint but is not considered
exhaustive.
LOCATABLEclassRoot class of all information model classes that can be archetyped.
Most classes in the openEHR reference model inherit from the LOCATABLE class, which defines the
idea of locatability in an archetyped structure. LOCATABLE defines a runtime name and an
archetype_node_id.
LOCATABLEartifact
LOCATABLE_REFclassPurpose Reference to a LOCATABLE instance inside the top-level content structure inside a
VERSION<T>; the path attribute is applied to the object that VERSION.data points
to.
LOCATABLE_REFartifact
locationattributeThe actual location where the session occurred, e.g. microbiol lab 2 ,
home , ward A3 and so on.
locationattributeIdentifier of the particular site/facility within an organisation which handled
the item. For computability, this identifier needs to be e.g. a PKI identifier
which can be included in the identifier list of the PARTY_IDENTIFIED object.
logical_pathsoperation
Set of language-dependent paths extracted from archetype. Paths obey the same
syntax as physical_paths, but with node_ids replaced by their meanings from the
ontology.
lowerrelation
lowerattributelower bound.
lower_includedattributelower boundary value included in range if not lower_unbounded.
lower_unboundedattributelower boundary open (i.e. = -infinity)
