assigning_location

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

This template describes the assignment of a location to an entity_for_location.

The following input parameters are defined for this template:

The following reference parameters are defined for this template:

-- The template assigning_location has an external reference -- locn_asst. Bind this to the local external reference -- location_assignment. It can now be the target for assigned dates %^locn_asst = $assigning_location.locn_asst% -- assign date to location_assignment in the role of "planned_start_date" /assigning_calendar_date(items=^locn_asst, date_class_name='Planned_start_date', date_ecl_id='urn:plcs:rdl:std', year=@2005, month=@4, day=@5)/

For example, to identify the name of a location by assigning an identification to the Location entity. E.g.

              -- The template assigning_location has an external reference
              -- location. Bind this to the local external reference
              -- Location. It can now be the target for assignments 
              %^location = $representing_location.location%
              -- assign 'Home' to the location in the role of "Name"
              -- as known by organisation with the name "Company_name".
              /assigning_identification(items=^location, 
              id='Home', 
              id_class_name='Name',
              id_ecl_id='urn:plcs:rdl:std'
              org_id='Company_name'
              org_id_class_name='Organization_name'
              org_id_ecl_id='urn:plcs:rdl:std')/

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.

-- Mark the Location entity as
-- referable when this template is used by binding it to the reference
-- parameter location
%^location = Location%
Location.description = '/IGNORE'
Location.name = '/IGNORE'

-- If the optional alt loc rep is provided then link to Location
Location.alternative_location_representations -> @alt_locn_rep

-- assign an identifier and classify it with input params
/assigning_identification(
    items=^location,
    id=@loc_id,
    id_class_name=@loc_id_class_name,
    id_ecl_id=@loc_id_ecl_id,
    org_id=@loc_org_id,
    org_id_class_name=@loc_org_id_class_name,
    org_id_ecl_id=@loc_org_id_ecl_id )/

-- Mark the location_assignment entity as
-- referable when this template is used by binding it to the reference
-- parameter id_assgn
%^locn_asst = Location_assignment%
Location_assignment.description = '/IGNORE'
Location_assignment.role = '/IGNORE'
Location_assignment.location_for_assignment -> ^location
Location_assignment.entity_for_location -> @entity_for_location

-- provide the role of the identification by classifying the location_assignment
/assigning_reference_data(
    items=^locn_asst,
    class_name=@la_class_name,
    ecl_id=@la_ecl_id)/

The following entities are instantiated with attributes as specified:

Entity in path	Value	Inherited from
Location.description	'/IGNORE'	—
Location.name	'/IGNORE'	—
Location_assignment.description	'/IGNORE'	—
Location_assignment.role	'/IGNORE'	—

The following section details how the assigning_location template can be optionally characterized by assigning other constructs to it. These are characterizations commonly applied to the template. The ISO 10303-239 EXPRESS model may enable other assignments to the entities instantiated by the template.

The following characterizations may apply:

Characterization Assigning date

NOTE this characterization is optional.

Dates can be associated with the assignment of a location_assignment by using the template assigning_calendar_date. For example, the planned start and end date of a location assigned to an instance of Location_assignment.

Figure 5 — Template Configuration with Optional Calendar Date Assignment.

When instantiating the templates for assigning a date to a referenced location_assignment this requires the use of the reference parameter $assigning_location.locn_asst to identify the assigning_location instantiated by the template Location_assignment).

Characterization Assigning reference data

NOTE this characterization is optional.

Reference data can be associated with the location instance by using the template assigning_reference_data. For example, the type of location may be assigned to an instance of Location.

Figure 6 — Template Configuration with Optional Calendar Date, Reference Data and Identification Assignment

Care needs to be taken to avoid potential conflicts with the (optional - [0:?]) alternative_location_representations attribute as the subtypes of Location_representation provide the major typing mechanism for this part of the model. Also note that these subtypes are handled in a separate set of templates.

NOTE The mechanism for assigning reference data to a location is shown in figure Figure 6.

Characterization Assigning identifiers

NOTE this characterization is optional.

Further Identifiers can be associated with an instance of location_assignment by using the template assigning_identification. For example, an id may be assigned to an instance of Location_assignment, if required.

NOTE The mechanism for assigning identifier is shown in figure Figure 6.

Characterization Location Relationships

NOTE this characterization is optional.

Two Locations can be associated together by a Location_relationship with the relationship classified appropriately to describe the role (or purpose) of the relationship. This can be achieved by using the templates assigning_location and assigning_reference_data. There may be two assigning_location templates used, which create different Locations for one (or more) entities (e.g. activity). The relationship is classified as a type of "Location relationship role" (urn:plcs:rdl:std:Location relationship role) (or sub-class, e.g. "Alternative location" (urn:plcs:rdl:std:Alternative location)) using the assigning_reference_data template. This is shown in the figure below.

Figure 7 — Template Configuration for Location Relationships

NOTE Due to the simplicity, no separate template has been created for representing these relationships.
