DutyNodes extension:
The DutyNodes package extends the Business Activity library and runtime engine by providing platform support for process-related obligation policies.
Main Features (in Version 0.1.1):
- Specification of process-related duties for defining obligation policies.
- Specification of duty hierarchies (i.e. refining duties via sub-duties).
- Many-to-many duty-to-task assignments.
- Revocation of duty-to-task assignments.
- Assignment of compensation actions to duties.
- Revocation of compensation actions.
- Definition of time constraints for duties.
- Functions for checking time constraints.
- Duty-aware redefinition of task-to-role assignments.
- Duty-aware redefinition of the task allocation mechanism.
- Additional duty-related introspection options.

DutyNodesConstraints
extension: The DutyNodesConstraints package
extends the DutyNodes package with support for the definition of
static and dynamic mutual exclusion constraints as well as
role-binding and subject-binding constraints for duties. Several
consistency checks ensure the consistency between design-time
and runtime models. The DutyNodesConstraints package has to be
used in combination with the DutyNodes package (see above).
Main Features (in Version 0.1.1):
- Definition of mutual exclusion constraints and binding constraints for duties.
- Duty-aware redefinition of functions for mutual exclusion and binding constraints.
- Redefinition of the duty-to-task assignment function.
- Redefinition of the task-to-role assignment function.
- Duty-aware checking of mutual exclusion and binding constraints at runtime.

Delegation
extension: The Delegation package enables
delegation of tasks, duties, and roles. If a software component
uses the delegation functions for duties, this package requires
the DutyNodes package (see above).
Main Features (in Version 0.1.1):
- Definition of delegation roles.
- Definition of delegation role-hierarchies.
- Single-step and multi-step delegation of roles.
- Permanent and temporary delegation of roles.
- Definition of task-to-role delegations and role-to-role delegations.
- Revocation of task-to-role and role-to-role delegations.
- Assignment of subjects to delegation roles (role-to-subject delegation).
- Revocation of role-to-subject delegations.
- Additional introspection options for delegation roles.

ContextConstraints
extension: The ContextConstraints package
extends the Business Activity library and runtime engine with
platform support for context constraints in BusinessActivities. A
context constraint considers additional contextual information in
task-related access control decisions.
Main Features (in Version 0.1.1):
- Definition of context constraints and context conditions.
- Linking and unlinking of context constraints and context conditions.
- Linking and unlinking of tasks and context constraints.
- Specification of operands and operators for particular context conditions.
- Evaluation of context constraints for all tasks in a certain process instance at runtime,.
- Additional introspection options for context constraints and context conditions.
