Introduction
Industrial consortia have engaged in the standardization of domain-specific objects including business
process models and software components using common modelling facilities and interchange facilities such
as UML and XML. They are very active in standardizing domain-specific business process models and
standard modelling constructs such as data elements, entity profiles, and value domains.
ISO/IEC 19763 provides registration mechanisms for different kinds of information resources in business
domains, such as ontologies, roles, goals, processes, and services. Faced with the abundant and
heterogeneous models, how to select appropriate services and/or models to meet user-requests becomes an
important issue. Based on the metamodels defined in parts 3, 5, 7 and 8 of ISO/IEC 19763, this technical
report describes a framework and procedures for model selection so as to help users discover corresponding
models or services that support their requests.

4 Preliminaries of ODMS
In order to show how to realize On Demand Model Selection (ODMS), some preliminaries need to be
introduced first. The associations in RGPS classes and their semantic annotations form the basis for ODMS.
The RGPS associations specify how the different models are related, and the ontology concepts used in the
semantic annotations form the basis for matching user-requests with registered models.
4.1 Associations in RGPS
Since the scope of ISO/IEC TR 19763-9 is limited to model selection based on ISO/IEC 19763-5,
ISO/IEC 19763-7, and ISO/IEC 19763-8, the three parts will be introduced first.
ISO/IEC 19763-5 specifies a metamodel to enable organizations to create a registry storing the administrative
and descriptive information of process models. The process model registration metamodel is intended to
promote semantic discovery and reuse of process models within/across organizations.
ISO/IEC 19763-7 specifies a metamodel to enable organizations to create a registry storing the administrative
and descriptive information of service models. The service model registration metamodel is intended to
promote semantic discovery and reuse of services within/across organizations.
ISO/IEC 19763-8 specifies a metamodel to enable organizations to create a registry storing the administrative
and descriptive information of role and goal models. The role and goal model registration metamodel is
intended to promote semantic discovery and reuse of role and goal models within/across organizations.
For the purposes of this technical report, RGPS is viewed as a generic term referring to the method of
applying associations between RGPS models to support ODMS.
As shown in Figure 1, there are associations between the metamodels defined in parts 5, 7 and 8 of
ISO/IEC 19763.

Figure 1 – Associations in RGPS
The associations in ISO/IEC 19763-8 are:

Each role sets zero, one or more goals.
Each goal is set by zero, one or more roles.

Each role is involved in processes through zero, one or more process involvements.
Each process involvement represents the involvement in processes of one and only one role.

Each role is involved in services through zero, one or more service involvements.
Each service involvement represents the involvement in services of one and only one role.

Each involvement type is used to describe zero, one or more process involvements.
Each process involvement is described by one and only one involvement type.

Each involvement type is used to describe zero, one or more service involvements.
Each service involvement is described by one and only one involvement type.

The associations in ISO/IEC 19763-7 are:

Each service contains zero, one or more service operations.
Each service operation is contained by one and only one service.

The associations that associate ISO/IEC 19763-5 with ISO/IEC 19763-8 are:

ISO/IEC TR 19763-9:2015(E)

Each process is used to achieve zero, one or more goals.
Each goal is achieved by zero, one or more processes.

Each process is represented in zero, one or more process involvements.
Each process involvement is involved in one and only one process.

The associations that associate ISO/IEC 19763-7 with ISO/IEC 19763-8 are:

Each service is used to achieve zero, one or more goals.
Each goal is achieved by zero, one or more services.

Each service operation is used to achieve zero, one or more goals.
Each goal is achieved by zero, one or more service operations.

Each service is represented in zero, one or more service involvements.
Each service involvement is involved in one and only one service.

The associations that associate ISO/IEC 19763-7 with ISO/IEC 19763-5 are:

Each service operation is used to fully realize zero, one or more processes.
Each process is fully realized by zero, one or more service operations.

NOTE 1 The instance of involvement type can be performer, beneficiary, customer, and so on.
NOTE 2 In the case that a process is fully realized by a set of service operations, the process should be decomposed into
a certain level such that each sub-process of the process can be fully realized by a service operation.
To facilitate ODMS within an organization’s set of registries based on the metamodels defined in the various
parts of ISO/IEC 19763, the associations in RGPS should be recorded. However, it is not necessary to
maintain a separate registry to record these associations. In order to record these associations, the following
strategies might be adopted. The associations between processes with their roles and goals will be registered
in a registry based on the metamodel defined in ISO/IEC 19763-5; the associations between services with
their roles, goals, and processes will be registered in a registry based on the metamodel defined in
ISO/IEC 19763-7. Note that Figure 1 only shows the associations among roles, goals, processes and services,
not all associations in the metamodels defined in parts 5, 7 and 8 of ISO/IEC 19763.
4.2 Semantic annotation
An essential issue in ODMS is how to match user-requests with registration information of the registered
RGPS models. The use of semantic annotations of registered models based on domain specific ontologies
can be used to bridge the gap between the registered RGPS models, as well as the gap between user-
requests and the registration information.
In order to semantically annotate the registered RGPS models, two kinds of domain sub-ontologies, entity
ontology and operation ontology, are considered (Figure 2). The entity ontology mainly describes the entity
concepts and semantic relationships among them, and the operation ontology mainly describes the
operational or functional concepts as well as semantic relationships among them. The domain ontology can
be used to annotate the goal class with attributes in a registry based on the
metamodel defined in ISO/IEC 19763-8. When registering a process in a registry based on the metamodel
defined in ISO/IEC 19763-5, the goals achieved by the process can be defined by setting the reference
achieved_goal, whose values are from goals registered in the registry based on the metamodel defined in
ISO/IEC 19763-8, i.e., the same ontology is used to annotate the goals achieved by the process.
For example, given a transportation domain goal “Book ticket” with attributes ,
where the goal operation is annotated by the concept “Book” in the operation ontology of transportation
domain, while the goal object would be annotated by the concept “Ticket” in the entity ontology of
transportation domain. A user searching for a process that can achieve a goal “Reserve ticket” might find the
concept in the transportation domain ontology with a synonym “Book ticket”. Using the same ontology to
annotate the RGPS models enables the ontology to provide support for semantic matching based on concept
synonyms. Then the processes that are associated with the concept, regardless of whether the process is
named “Book ticket” or “Reserve ticket”, will be searched.

ISO/IEC TR 19763-9:2015(E)

Provision is made in ISO/IEC 19763 for all models and model elements to be annotated with concepts within
ontologies registered in a registry based on the metamodel defined in ISO/IEC 19763-3. Hence, in parts 5, 7
and 8 of ISO/IEC 19763, the metaclasses of role, goal, role and goal model, process, process model, event,
resource, service model, service, service operation, input and output can be annotated by concepts from
domain ontologies, and these annotations can be used to support model discovery across registries based on
the metamodels defined in the various parts of ISO/IEC 19763.

Figure 2 – Semantic annotation in RGPS
A registry based on the metamodels defined in the various parts of ISO/IEC 19763 does not hold all of the
semantics of the registered models, but it is possible to retrieve all the semantics using the identifiers of the
models registered in the registry. Figure 1 describes the associatio
