This document discusses Remedy IT's initial submission to the UCM specification. It focuses on an IDL-based programming model and includes: - An overview of their submission and focus on the IDL programming model specification (PSM) - A description of their implementation of Generic Interaction Support (GIS) using IDL interfaces to define provided and used services - An outline of their proposed UCM container architecture, including extensible container services and a small core container - Details on key UCM elements like components, connectors, homes, and assemblies, and how they would be supported - Next steps including an initial implementation in their CIAOX11 distribution supporting DDS4CCM events

UCM Initial Submission

5. 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?

6. Generic Interaction Support
Our submission is based on the Generic Interaction
Support (GIS) coming originally from DDS4CCM
Components provide and use services which are
defined using IDL interfaces
IDL interfaces are local by default
Using GIS multiple interaction patterns are defined
An interaction pattern is delivered at runtime by
connector fragments

7. Container (1)
The UCM container should be small and extensible
Hosts all components, connector fragments, homes,
and services
• Users provide components and homes containing
the business logic
• Middleware vendors are providing connector
fragments containing the concrete IPC
• UCM vendors provide container services which
extend the basic container

8. Container (2)
The container manages all installed instances
The term ‘container’ doesn’t contain the component
specific generated glue code

9. Container Services
Container services are a way to create a simple
container
For example timer support and execution model
Services are installed into the container and can be
retrieved by other entities in the same container
Provide a way to adapt the behavior of the container
without having to replace the full container

10. Component Messaging
Services
Provides the execution model
Contained out of two entities, a queue manager and
a dispatch manager
Different implementations can provide different
models
• Single threaded
• Multi threaded
• Queue per container
• Queue per component
• Etc
Advanced implementations can also do deadline
monitoring

11. Components
Components are user defined
Provide services to other components
Uses services from other components
Do have a context providing references at runtime for
the ports of a component
Has a specific lifecycle model
Can define attributes for configuration purposes

12. Connectors
Connectors connect a component to something else
• Components, legacy systems, hardware, etc
Connector fragments implement functionality to
translate a port to a specific middleware, other
services, or hardware
Copyright © 201412

13. Home
Component factory at runtime
Can have attributes for configuration purposes
Copyright © 201413

14. Assemblies
Assemblies simplify the composition of a larger
system
Assemblies will be supported in some way at
deployment level, we don’t want to flatten them out
like currently with LwCCM

15. Interaction patterns
Request/reply and publish/subscribe are defined as
interaction patterns
IDL defined template modules that are defined using
the IDL type system
Components uses the provided ports
Connectors are defined outside of the templated
module containing the interaction patterns; makes it
possible to extend the concrete connectors later
