Figure 1 — Graphical Representation for Business Object Task List

Task List:

The definition of an Task List object is: Data about an list of tasks that are important in a particular context.

Attribute name	Attribute description	Attribute type	Optionality
Context	This is the context within which the task list was created.	Intrinsic	Mandatory
ID	This is the identifier of the task list.	Identifier	Mandatory
Name	This is the name of the task list.	Intrinsic	Mandatory
Related task	This is the reference to the tasks that constitute the task list.	Task	Mandatory
Version	This is the version of the task list.	Intrinsic	Mandatory

Table 1 — Task List: attribute details

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

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

%^target = $task_list.task_list%

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

Unique constraint: Unique Task_list

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

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

/task_list(ID='TL01', ID_source_organization='UK_Defence', Name='My task list', Name_source_organization='UK_Defence', Version='v01', Context='UK_Defence context', Related_tasks='@77', Related_tasks='@198')/

(an illustration of the consolidated task_list 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:
