2. Our focus area
As a company we focus, at this moment, on the
runtime part of the component framework
Our code generators and tooling take IDL as input
Therefore our UCM initial submission focuses on the
IDL PSM
The UML meta model has to be added, could we
make create a separate IDL4 meta model?

3. Starting constraints
Components provide and use services which are
defined using IDL interfaces
IDL interfaces are local by default

4. Container (1)
The UCM container should be small
The container manages all installed instances
The ‘container’ doesn’t contain the component
specific generated glue code

5. Component
Components are user defined
Provide services to other components using facets
Uses services from other components using
receptacles
Have a predefined lifecycle model

deploy
on_create()
on_activate()
on_destroy()
on_remove()
Created
Passive
Active
on_passivate()

7. Component API
interface Component {
void on_create (in string instance_id, in ConfigValue values, in
Container the_container) throw (ConfigurationError);
void on_activate ();
void on_passivate ();
void on_remove ();
void on_destroy ();
object get_facet (in string facet_name) throw (UnknownFacet);
object set_receptacle (in string receptacle_name, in object reference,
in string connection_name) throw (UnknownReceptacle);
};

8. Next steps?
Work on the interaction patterns
Look at how interaction patterns are tied to a specific
component
• IDL3+
• IDL annotations
Execution models
