Figure 9.5 – Main (Internal) Pool without boundaries
BPMN specifies a marker for Pools: a multi-instance marker May be displayed for a Pool (see Figure 9.6). The marker is used if the Participant defined for the Pool is a multi-instance Participant. See page 116 for more information on Participant multiplicity.
The marker for a Pool that is a multi-instance MUST be a set of three vertical lines in parallel. The marker, if used, MUST be centered at the bottom of the shape.

Figure 9.6 – Pools with a Multi-Instance Participant Markers
9.3.1Participants
A Participant represents a specific PartnerEntity (e.g., a company) and/or a more general PartnerRole (e.g., a buyer, seller, or manufacturer) that are Participants in a Collaboration. A Participant is often responsible for the execution of the Process enclosed in a Pool; however, a Pool MAY be defined without a Process.
Figure 9.7 displays the class diagram of the Participant and its relationships to other BPMN elements. When Participants are defined they are contained within a Collaboration, which includes the sub-types of Choreography,
GlobalConversation, or GlobalChoreographyTask.

Figure 9.7 – The Participant Class Diagram
The Participant element inherits the attributes and model associations of BaseElement (see Table 8.5). Table 9.2 presents the additional attributes and model associations for the Participant element.

Table 9.2 – Participant attributes and model associations
Attribute Name |
Description/Usage |
|
|
name: string [0..1] |
Name is a text description of the Participant. The name of the |
|
Participant can be displayed directly or it can be substituted by the |
|
associated PartnerRole or PartnerEntity. Potentially, both the |
|
PartnerEntity name and PartnerRole name can be displayed for |
|
the Participant. |
|
|
processRef: Process [0..1] |
The processRef attribute identifies the Process that the |
|
Participant uses in the Collaboration. The Process will be |
|
displayed within the Participant’s Pool. |
|
|
partnerRoleRef: PartnerRole [0..*] |
The partnerRoleRef attribute identifies a PartnerRole that the |
|
Participant plays in the Collaboration. Both a PartnerRole and a |
|
PartnerEntity MAY be defined for the Participant. This attribute is |
|
derived from the participantRefs of PartnerRole. |
partnerEntityRef: PartnerEntity [0..*] |
The partnerEntityRef attribute identifies a PartnerEntity that |
|
the Participant plays in the Collaboration. Both a PartnerRole and a |
|
PartnerEntity MAY be defined for the Participant.This attribute is |
|
derived from the participantRefs of PartnerEntity. |
interfaceRef: Interface [0..*] |
This association defines Interfaces that a Participant supports. The |
|
definition of Interfaces is provided on page 102. |
participantMultiplicity: |
The participantMultiplicityRef model association is used to |
participantMultiplicity [0..1] |
define Participants that represent more than one (1) instance of the |
|
Participant for a given interaction. See the next sub clause for more |
|
details on ParticipantMultiplicity. |
endPointRefs: EndPoint [0..*] |
This attribute is used to specify the address (or endpoint reference) of |
|
concrete services realizing the Participant. |
|
|
PartnerEntity
A PartnerEntity is one of the possible types of Participant (see above).
The PartnerEntity element inherits the attributes and model associations of BaseElement (see Figure 8.5). Table 9.3 presents the additional attributes and model associations for the PartnerEntity element.
Table 9.3 – PartnerEntity attributes
Attribute Name |
Description/Usage |
|
|
name: string |
Name is a text description of the PartnerEntity. |
|
|
participantRef: Participant [0..*] |
Specifies how the PartnerEntity participates in Collaborations and |
|
Choreographies. |

115 |
PartnerRole
A PartnerRole is one of the possible types of Participant (see above).
The PartnerRole element inherits the attributes and model associations of BaseElement (see Figure 8.5). Table 9.4 presents the additional attributes and model associations for the PartnerRole element.
Table 9.4 – PartnerRole attributes
Attribute Name |
Description/Usage |
|
|
name: string |
Name is a text description of the PartnerRole. |
|
|
participantRef: Participant [0..*] |
Specifies how the PartnerRole participates in Collaborations and |
|
Choreographies. |
Participant Multiplicity
ParticipantMultiplicity is used to define the multiplicity of a Participant.
For example, a manufacturer can request a quote from multiple suppliers in a Collaboration.
