NOTE The template has been defined in the context of UK_Defence. Refer to the business context for details of related templates.

NOTE An explanation of a template and the associated instantiation path is provided in the Template overview section.

This template describes how to represent UK_Defence skill using Type_of_person_definition.

This represents an informally defined ability, technique or expertise to do something well. A skill may be physically or mentally based. A skill may be possessed be a person. Examples: Driving a car, mental arithmetic.

For further information about the representation of a skill, see below.

The skill business object is used by those UK_Defence Data Exchange Specifications that require information about an informally defined ability, technique or expertise to do something well.

The definition of a skill object is: Data about an informally defined ability, technique or expertise to do something well.

The EXPRESS-G diagram in Figure 2 shows the templates and EXPRESS entities that are required to represent the template "skill". The text highlighted in blue shows the template parameters.

The following input parameters are defined for this template:

The following reference parameters are defined for this template:

Allow the Type_of_person entity instantiated in this path to be referenced when this template is used.

Note: The Type_of_person entity can be referenced in a template path by:

%^target = $skill.type_of_person%

where target is the parameter to which the Type_of_person is bound.

Allow the Type_of_person_definition entity instantiated in this path to be referenced when this template is used.

Note: The Type_of_person_definition entity can be referenced in a template path by:

%^target = $skill.skill%

where target is the parameter to which the Type_of_person_definition is bound.

The following parameter combinations specify a uniqueness constraint:

Unique constraint: Unique skill

Each instance of the entity (Type_of_person_definition) within the data set shall be uniquely identified by a combination of the following parameters on this template (skill) namely: ID, source_organization.
The instance is referenced by the following template parameter: skill.

Any given identifier shall only be assigned to a skill once.

The instantiation path shown below specifies the entities that are to be instantiated by the template.

A description of templates and the syntax for the instantiation path is provided in the Templates Help/Information section.

-- Type_of_person
Type_of_person
%^type_of_person = Type_of_person%

-- Type_of_person_definition
Type_of_person_definition
%^skill = Type_of_person_definition%
Type_of_person_definition.name = '/IGNORE'
Type_of_person_definition.description = '/IGNORE'
/identifier(
    ID=@ID,
    source_organization=@source_organization,
    type='Skill_identification_code',
    items=^skill)/
/identifier(
    ID=@name,
    source_organization=@name_source_organization,
    type='Skill_name',
    items=^skill)/
/assigning_descriptor(
    descr=@description,
    class_name='Description',
    ecl_id='urn:plcs:rdl:std',
    is_assigned_to=^skill)/

The following entities are instantiated with attributes as specified:

Entity in path	Value	Inherited from
Type_of_person_definition.name	'/IGNORE'	—
Type_of_person_definition.description	'/IGNORE'	—

The instance diagram in Figure 4 shows an example of the EXPRESS entities and templates that are instantiated by the template:

/skill(ID='sk01', source_organization='UK_Defence', name='Driving a car', name_source_organization='UK_Defence', description='Ability to drive a manual transmission car to standard level')/

(an illustration of the consolidated skill template is shown in Figure 5 below.)

The instance diagram in Figure 5 shows the graphic symbol for the template that is to be used in other instance diagrams. The example template is:

/skill(ID='sk01', source_organization='UK_Defence', name='Driving a car', name_source_organization='UK_Defence', description='Ability to drive a manual transmission car to standard level')/

No common characterizations of the template skill have been identified. However, the ISO 10303-239 EXPRESS model may enable other assignments to the entities instantiated by the template.
