The notion of protection only appears at the
level of package components. The features
are always public. This should not pose a
problem as far as COTRE is concerned. It is
simply necessary to divide the component
up into several sub-components, some of
which implement exported operations while
others supply internal operations.

Refers back to a source code declaration.
May therefore provide a link between a

Table 2 – Coverage of COTRE attributes
The following properties are defined explicitly by the COTRE language:
Name Type Applies to Default
value
Notes
cotre::ceiling_priority integer DATA - Applies to DATA components
that are protected by the PCP
access protocol. Enables
definition of the priority taken
by the threads accessing data
during their critical section.
cotre::Description string All components &
sub-components
- Informal comments, requirement
traceability info. etc.
cotre::Min_Time time THREAD - Minimum time between 2 executions
of a sporadic thread.
cotre::Phase time THREAD 0.0s Period start time shifted for
periodic threads.

cotre::Priority integer THREAD - Basic thread priority (semantics
depend on scheduling
strategy).
cotre::Protected boolean SUBPROGRAM false True if the sub-program executions
are exclusive with the
component’s other sub-programs;
false in the opposite
case.
cotre::Reentrant boolean SUBPROGRAM false True if the sub-program is
reentrant, false in the opposite
case.
