Linked.Archi UML 2.5.1 Ontology: Description back to ToC

RDF/OWL formalization of the OMG Unified Modeling Language (UML) 2.5.1 metamodel for use in the Linked.Archi architecture knowledge graph. Covers structural classifiers (Class, Interface, Component, Package), behavioral elements (Activity, StateMachine, Interaction), deployment concepts (Node, Artifact), and use cases (Actor, UseCase). Relationship types follow the Linked.Archi three-declaration qualified relationship pattern. This ontology is INFORMED BY the OMG Ontology Definition Metamodel (ODM, formal/2014-09-02) but does NOT apply ODM directly. ODM Annex D maps UML model instances (M1) to OWL; this ontology represents the UML metamodel itself (M2) as OWL classes so that UML model data can be typed in a knowledge graph. We adopt ODM principles (Class→owl:Class, Generalization→rdfs:subClassOf, Package→owl:Ontology) but depart from ODM for associations (three-declaration pattern), enumerations (SKOS), constraints (SHACL), and domain/range (arch:domainIncludes). See the skos:scopeNote for the full comparison. This is not an official OMG document. It is a Linked.Archi interpretation of the UML specification for semantic architecture modeling.

A qualified relationship representing a UML Association — a structural relationship between Classifiers that specifies connections among their instances. Maps to UML 2.5.1 §11.5 Association.
editorial note
UML 2.5.1 §11.5 makes an Association both a Classifier and a Relationship, which is what gives it a name: Classifier ⊑ Namespace ⊑ NamedElement ⊑ Element. The Classifier superclass is also why an Association can itself be typed, be generalized and own Properties — an AssociationClass is not a special case bolted on, it is what being a Classifier already permits. Do not read arch:domainIncludes :Classifier as saying the same thing. That states what an Association *relates*; rdfs:subClassOf states what it *is*. The two were conflated here until 0.3.0, and the result was that an unlabelled association passed umlsh:NamedElementShape while an unlabelled transition failed it.
has super-classes

General Orderingc back to ToC or Class ToC

IRI: https://meta.linked.archi/uml/onto#GeneralOrdering

A GeneralOrdering represents a binary relation between two OccurrenceSpecifications, to describe that one OccurrenceSpecification must occur before the other in a valid trace. This mechanism provides the ability to define partial orders of OccurrenceSpecifications that may otherwise not have a specified order — for example, events on different Lifelines that are not connected by a Message but must still be ordered. Maps to UML 2.5.1 §17.3 GeneralOrdering. Source: .reference/omg/uml/ptc-18-01-01.xmi (xmi:id="GeneralOrdering").
editorial note
In UML XMI, GeneralOrdering has two properties: - before : OccurrenceSpecification [1] — the occurrence that must happen first - after : OccurrenceSpecification [1] — the occurrence that must happen second In Linked.Archi RDF, these are modeled as :orderingBefore and :orderingAfter object properties on the GeneralOrdering instance. See .reference/omg/uml/ptc-18-01-01.xmi lines 9928–9963.

A qualified relationship representing a UML Generalization — a taxonomic relationship from specific to general Classifier.
editorial note
A DirectedRelationship and nothing more. UML 2.5.1 §9.9 does not make Generalization a NamedElement, so it has no name — deliberately, and unlike :Association and :Dependency. Nothing should require a skos:prefLabel on one.
has super-classes
Directed Relationship c, qualified relationship c
is in range of
qualified generalizes op

Includec back to ToC or Class ToC

IRI: https://meta.linked.archi/uml/onto#Include

An InformationFlow specifies that one or more information items circulate from its sources to its targets. Maps to UML 2.5.1 §20.2 InformationFlow.
editorial note
UML 2.5.1 §20.2 makes an InformationFlow a PackageableElement and a DirectedRelationship. Declared as :Element until 0.3.0, which reached :Element by the shortest route but skipped :NamedElement, so an InformationFlow could not be named.
has super-classes
Directed Relationship c, Packageable Element c, qualified relationship c

Interactionc back to ToC or Class ToC

IRI: https://meta.linked.archi/uml/onto#Interaction

An Interaction is a unit of Behavior that focuses on the observable exchange of information between connectable elements. It owns an ordered set of InteractionFragments (the fragment property), a set of Lifelines (the participants), and a set of Messages (the communications). An Interaction is itself an InteractionFragment, allowing nesting. Maps to UML 2.5.1 §17.2 Interaction. Source: .reference/omg/uml/ptc-18-01-01.xmi (xmi:id="Interaction").
Example
A "Login" sequence diagram is modeled as:
  ex:LoginInteraction a uml:Interaction ;

Interaction Fragmentc back to ToC or Class ToC

IRI: https://meta.linked.archi/uml/onto#InteractionFragment

InteractionFragment is the abstract base metaclass for all elements that can appear in the ordered fragment list of an Interaction or InteractionOperand. Every InteractionFragment is conceptually like an Interaction by itself — it covers one or more Lifelines and occupies a position in the temporal ordering of the enclosing Interaction. Concrete subclasses include OccurrenceSpecification, CombinedFragment, InteractionUse, ExecutionSpecification, and StateInvariant. Maps to UML 2.5.1 §17.3 InteractionFragment. Source: .reference/omg/uml/ptc-18-01-01.xmi (xmi:id="InteractionFragment").
editorial note
Key properties from the UML metamodel: - covered : Lifeline [0..*] — the lifelines this fragment involves - enclosingInteraction : Interaction [0..1] — the owning Interaction - enclosingOperand : InteractionOperand [0..1] — the owning operand (if nested) - generalOrdering : GeneralOrdering [0..*] {composite} — explicit ordering constraints See .reference/omg/uml/ptc-18-01-01.xmi lines 10157–10215.

Messagec back to ToC or Class ToC

IRI: https://meta.linked.archi/uml/onto#Message

A Message defines a particular communication between Lifelines of an Interaction. Each Message has a sendEvent and a receiveEvent (both MessageEnd instances), a messageSort indicating the type of communication (synchCall, asynchCall, asynchSignal, createMessage, deleteMessage, reply), and an optional signature referencing the Operation or Signal being invoked. Messages are the arrows in a sequence diagram. Maps to UML 2.5.1 §17.4 Message. Source: .reference/omg/uml/ptc-18-01-01.xmi (xmi:id="Message").
editorial note
Message ordering in a sequence diagram is NOT a property of the Message itself — it is determined by the position (sequenceNumber) of the MessageOccurrenceSpecifications that serve as its sendEvent and receiveEvent within the Interaction::fragment ordered collection. Message M1 precedes M2 if M1.sendEvent.sequenceNumber < M2.sendEvent.sequenceNumber. See UML-DD-9 in design-decisions.md for the full rationale.

Message Occurrence Specificationc back to ToC or Class ToC

IRI: https://meta.linked.archi/uml/onto#MessageOccurrenceSpecification

A MessageOccurrenceSpecification represents the sending or receiving of a Message on a specific Lifeline. It is both an OccurrenceSpecification (a point in time on a Lifeline) and a MessageEnd (an endpoint of a Message). This dual inheritance is the key structural element that connects Messages to the temporal ordering: the sequenceNumber of the MessageOccurrenceSpecification determines when the send or receive occurs relative to other events on the same Lifeline. Maps to UML 2.5.1 §17.4 MessageOccurrenceSpecification. Source: .reference/omg/uml/ptc-18-01-01.xmi (xmi:id="MessageOccurrenceSpecification").

IRI: https://meta.linked.archi/uml/onto#covered

References the Lifeline(s) that an InteractionFragment involves. For OccurrenceSpecification, this is exactly one Lifeline (the one on which the event occurs). For CombinedFragment, it may be multiple Lifelines (all those spanned by the fragment box). Maps to UML 2.5.1 §17.3 InteractionFragment::covered [0..*] and §17.4 OccurrenceSpecification::covered [1] (redefines to exactly one). Source: .reference/omg/uml/ptc-18-01-01.xmi (xmi:id="InteractionFragment-covered", "OccurrenceSpecification-covered").

A relationship from a DeployedArtifact to a DeploymentTarget. Maps to UML 2.5.1 §19.2 Deployment.

Executionop back to ToC or Object Property ToC

IRI: https://meta.linked.archi/uml/onto#execution

The ExecutionSpecification that this ExecutionOccurrenceSpecification starts or finishes. This links the occurrence (a point in time) to the execution period it delimits. Maps to UML 2.5.1 §17.5 ExecutionOccurrenceSpecification::execution [1]. Source: .reference/omg/uml/ptc-18-01-01.xmi (xmi:id="ExecutionOccurrenceSpecification-execution").

Execution Finishop back to ToC or Object Property ToC

IRI: https://meta.linked.archi/uml/onto#executionFinish

The OccurrenceSpecification that marks the end of this ExecutionSpecification (the bottom of the activation bar). Typically this is the sendEvent of the reply message. Maps to UML 2.5.1 §17.5 ExecutionSpecification::finish [1]. Source: .reference/omg/uml/ptc-18-01-01.xmi (xmi:id="ExecutionSpecification-finish").

Execution Startop back to ToC or Object Property ToC

IRI: https://meta.linked.archi/uml/onto#executionStart

The OccurrenceSpecification that marks the beginning of this ExecutionSpecification (the top of the activation bar). Typically this is the receiveEvent of an incoming message. Maps to UML 2.5.1 §17.5 ExecutionSpecification::start [1]. Source: .reference/omg/uml/ptc-18-01-01.xmi (xmi:id="ExecutionSpecification-start").

Extendsop back to ToC or Object Property ToC

IRI: https://meta.linked.archi/uml/onto#extends

A relationship from an extending UseCase to an extended UseCase. Maps to UML 2.5.1 §18.2 Extend.

Formal Gateop back to ToC or Object Property ToC

IRI: https://meta.linked.archi/uml/onto#formalGate

The Gates that form the message interface between this Interaction and any InteractionUses which reference it. Formal gates define the "ports" through which messages can enter or leave a reusable Interaction. Maps to UML 2.5.1 §17.2 Interaction::formalGate [0..*] {composite}. Source: .reference/omg/uml/ptc-18-01-01.xmi (xmi:id="Interaction-formalGate").

Generalizesop back to ToC or Object Property ToC

IRI: https://meta.linked.archi/uml/onto#generalizes

A taxonomic relationship between a more general Classifier and a more specific Classifier. Maps to UML 2.5.1 §9.7 Generalization. ODM Annex D.3.3 maps UML Generalization to rdfs:subClassOf. The direct triple uses this predicate; the qualified form carries metadata.

Guard Constraintop back to ToC or Object Property ToC

IRI: https://meta.linked.archi/uml/onto#guardConstraint

The InteractionConstraint that guards an InteractionOperand. In UML, InteractionOperand::guard points to an InteractionConstraint instance (not directly to a string). This property provides the strict UML form; the :guard datatype property provides a pragmatic shortcut for simple cases. Maps to UML 2.5.1 §17.6 InteractionOperand::guard [0..1] {composite}. Source: .reference/omg/uml/ptc-18-01-01.xmi (xmi:id="InteractionOperand-guard").
editorial note
Both :guard (string shortcut) and :guardConstraint (object form) are supported. Use :guard for simple textual guards in architecture models. Use :guardConstraint when you need to attach minint/maxint (for loops) or when round-tripping from XMI where the guard is a full InteractionConstraint.

Has Fragmentop back to ToC or Object Property ToC

IRI: https://meta.linked.archi/uml/onto#hasFragment

The ordered set of InteractionFragments owned by this Interaction or InteractionOperand. Maps to UML 2.5.1 §17.2 Interaction::fragment [0..*] {ordered, composite} and §17.6 InteractionOperand::fragment [0..*] {ordered, composite}. The ordering of fragments defines the top-to-bottom temporal sequence in a sequence diagram. In RDF, the ordering is captured by :sequenceNumber on each fragment instance rather than by collection position. Source: .reference/omg/uml/ptc-18-01-01.xmi (xmi:id="Interaction-fragment", "InteractionOperand-fragment").
editorial note
In UML XMI, the fragment property is {ordered} — the XML document order of <fragment> elements defines temporal ordering. In RDF there is no inherent document order, so each fragment carries a :sequenceNumber integer. See UML-DD-9 in design-decisions.md for the rationale.

Has General Orderingop back to ToC or Object Property ToC

IRI: https://meta.linked.archi/uml/onto#hasGeneralOrdering

The GeneralOrdering constraints owned by this InteractionFragment. Maps to UML 2.5.1 §17.3 InteractionFragment::generalOrdering [0..*] {composite}. Source: .reference/omg/uml/ptc-18-01-01.xmi (xmi:id="InteractionFragment-generalOrdering").

Has Lifelineop back to ToC or Object Property ToC

IRI: https://meta.linked.archi/uml/onto#hasLifeline

The Lifelines owned by this Interaction. Maps to UML 2.5.1 §17.2 Interaction::lifeline [0..*] {composite}. In the UML metamodel this is a composite association — the Interaction owns its Lifelines. Source: .reference/omg/uml/ptc-18-01-01.xmi (xmi:id="Interaction-lifeline").

Has Messageop back to ToC or Object Property ToC

IRI: https://meta.linked.archi/uml/onto#hasMessage

The Messages owned by this Interaction. Maps to UML 2.5.1 §17.2 Interaction::message [0..*] {composite}. The Interaction owns all Messages that define communications between its Lifelines. Source: .reference/omg/uml/ptc-18-01-01.xmi (xmi:id="Interaction-message").

Has Operandop back to ToC or Object Property ToC

IRI: https://meta.linked.archi/uml/onto#hasOperand

The ordered set of InteractionOperands contained in this CombinedFragment. Each operand represents one branch (for alt), one iteration body (for loop), or one parallel track (for par). Maps to UML 2.5.1 §17.6 CombinedFragment::operand [1..*] {ordered, composite}. Source: .reference/omg/uml/ptc-18-01-01.xmi (xmi:id="CombinedFragment-operand").

Imports Packageop back to ToC or Object Property ToC

Values are the named individuals of :InteractionOperatorKind: alt, opt, loop, break, par, seq, strict, critical, neg, assert, ignore, consider. Maps to UML 2.5.1 §17.6 CombinedFragment::interactionOperator. Source: .reference/omg/uml/ptc-18-01-01.xmi (xmi:id="CombinedFragment-interactionOperator").

Merges Packageop back to ToC or Object Property ToC

IRI: https://meta.linked.archi/uml/onto#mergesPackage

A directed relationship between two Packages that indicates that the contents of the merged Package are combined into the receiving Package. Maps to UML 2.5.1 §12.2 PackageMerge.

Messageop back to ToC or Object Property ToC

IRI: https://meta.linked.archi/uml/onto#message

References the Message of which this MessageEnd is an endpoint. This is the inverse navigation from a MessageOccurrenceSpecification (or Gate) back to the Message it belongs to. In UML XMI, this appears as the "message" attribute on MessageOccurrenceSpecification elements. Maps to UML 2.5.1 §17.4 MessageEnd::message [0..1]. Source: .reference/omg/uml/ptc-18-01-01.xmi (xmi:id="MessageEnd-message").
editorial note
This property is the inverse of sendEvent/receiveEvent. Both directions are provided for query convenience: from Message to its endpoints (sendEvent/receiveEvent) and from endpoint back to its Message (message). In strict UML, the authoritative direction is Message→MessageEnd; this inverse is a convenience property.

Message Kindop back to ToC or Object Property ToC

IRI: https://meta.linked.archi/uml/onto#messageKind

The derived kind of the Message: complete, lost, found, or unknown. A Message is "complete" if both sendEvent and receiveEvent are present; "lost" if sendEvent is present but receiveEvent is absent; "found" if receiveEvent is present but sendEvent is absent; "unknown" if neither can be resolved. Maps to UML 2.5.1 §17.4 Message::messageKind {derived, readOnly}. Source: .reference/omg/uml/ptc-18-01-01.xmi (xmi:id="Message-messageKind").

Message Sortop back to ToC or Object Property ToC

IRI: https://meta.linked.archi/uml/onto#messageSort

The sort of communication reflected by the Message. Values are the named individuals of :MessageSort: synchCall (default), asynchCall, asynchSignal, createMessage, deleteMessage, reply. The messageSort determines the visual notation (solid vs. dashed arrow, filled vs. open arrowhead) and the behavioral semantics (blocking vs. non-blocking, creation vs. destruction). Maps to UML 2.5.1 §17.4 Message::messageSort. Source: .reference/omg/uml/ptc-18-01-01.xmi (xmi:id="Message-messageSort").
editorial note
Default value is synchCall. The signature must refer to an Operation (for synchCall, asynchCall, reply) or a Signal (for asynchSignal). See .reference/omg/uml/ptc-18-01-01.xmi constraint "signature_refer_to".

Ordering Afterop back to ToC or Object Property ToC

IRI: https://meta.linked.archi/uml/onto#orderingAfter

The OccurrenceSpecification that must occur second in a GeneralOrdering constraint. This is the "after" end of the ordering relation. Maps to UML 2.5.1 §17.3 GeneralOrdering::after [1]. Source: .reference/omg/uml/ptc-18-01-01.xmi (xmi:id="GeneralOrdering-after").

Ordering Beforeop back to ToC or Object Property ToC

IRI: https://meta.linked.archi/uml/onto#orderingBefore

The OccurrenceSpecification that must occur first in a GeneralOrdering constraint. This is the "before" end of the ordering relation. Maps to UML 2.5.1 §17.3 GeneralOrdering::before [1]. Source: .reference/omg/uml/ptc-18-01-01.xmi (xmi:id="GeneralOrdering-before").

Parameter Directionop back to ToC or Object Property ToC

IRI: https://meta.linked.archi/uml/onto#parameterDirection

The direction of a Parameter: in, out, inout, or return. Values are the named individuals of :ParameterDirectionKind: :In, :Out, :InOut, :Return. Maps to UML 2.5.1 §9.4 Parameter::direction. Source: .reference/omg/uml/ptc-18-01-01.xmi (xmi:id="Parameter-direction").
editorial note
Default is in.

Pseudostate Kindop back to ToC or Object Property ToC

IRI: https://meta.linked.archi/uml/onto#pseudostateKind

The kind of a Pseudostate: initial, deepHistory, shallowHistory, join, fork, junction, choice, entryPoint, exitPoint, or terminate. Values are the named individuals of :PseudostateKind. Maps to UML 2.5.1 §14.3 Pseudostate::kind. Source: .reference/omg/uml/ptc-18-01-01.xmi (xmi:id="Pseudostate-kind").
editorial note
Named :pseudostateKind rather than :kind because UML reuses the attribute name "kind" on Pseudostate, Transition and Connector, which would collapse into a single RDF predicate with three unrelated value sets. Default is initial.

The visibility of a NamedElement (public, private, protected, package). Maps to UML 2.5.1 §7.4 NamedElement::visibility. Values are the named individuals of :VisibilityKind: :Public, :Private, :Protected, :PackageVisibility.
editorial note
Was an owl:DatatypeProperty with rdfs:range xsd:string until 0.2.0, which contradicted its own documentation and admitted arbitrary strings. Now an ObjectProperty over the closed :VisibilityKind enumeration. Data using the string form (uml:visibility "private") must migrate to uml:Private.

Sequence Numberdp back to ToC or Data Property ToC

IRI: https://meta.linked.archi/uml/onto#sequenceNumber

The ordinal position of an InteractionFragment within its enclosing Interaction or InteractionOperand. This property captures the temporal ordering that UML XMI encodes via document order of the {ordered} fragment collection. Fragment with sequenceNumber 1 occurs before fragment with sequenceNumber 2, and so on. This is the primary ordering mechanism for sequence diagrams in Linked.Archi RDF.
editorial note
Alternative approaches considered: 1. rdf:List — rejected because lists are awkward to query in SPARQL and don't support random access or insertion 2. rdf:Seq — deprecated in modern RDF usage 3. Blank node chains — rejected for the same SPARQL ergonomics reasons The integer index approach is simple, queryable (ORDER BY ?seq), and consistent with how BPMN SequenceFlow uses explicit ordering in Linked.Archi.
