2 Model Driven Middleware for DRE Systems &  CoSMIC: Tailored towards the new OMG Deployment & Configuration specification  Aspect modeling  Model weaving via C-SAW (UAB sub)  Analysis & model checking (KSU) Metadata descriptors, deployment & launch scripts  Synthesize benchmarking suite, descriptor metadata, launch scripts  CIAO: QoS-enabled component middleware for DRE systems (WashU Collaboration)

3 CoSMIC Tools: Packaging (1/7)  Composable Adaptive Software Systems (COMPASS) tool to resolve the problem of packaging component functionality  Modeling paradigm that allows DRE application integrators to model the component assembly and packaging aspect  Model interpreter enables the synthesis of metadata describing component packages  Run-time tool support to parse the descriptors and create assemblies  POC: Krishnakumar Balasubramanian

4  Options Configuration Modeling Language (OCML)  Addressed ORB-level configuration aspects  OCML provides constraints on valid combinations of ORB parameters.  Synthesizes descriptors encoding the rules  Application developers model a set of ORB configuration parameters  Application developers validate their ORB configurations against these rules CoSMIC Tools: ORB Configuration (2/7) POC: Emre Turkaye

5  RT Event channel integration with CIAO containers  Patterns-based unified API to integrate event service, notification service and real-time event service  Model-driven synthesis of descriptor metadata for event channel configuration and integration  Permits event delivery for events between colocated components  Integration with KSU Cadena  POC: George Edwards Event channel integration in CIAO CoSMIC Tools: Event Channel Integration (3/7)

6  Federated Event Service Modeling Language (FESML)  Used to model a federation of event channels  Modeling entities include the producers, consumers, channels, networks, and gateways  Synthesizes the metadata to configure a federated event channel CoSMIC Tools: Federated Event Channels (4/7) POC: Gan Deng

7  Model Integrated Deployment and Configuration Environment for Composable Software Systems (MIDCESS)  Resolves deployment planning challenges  Allows modeling artifacts of deployment environment, such as nodes, networks, bridges  Synthesizes deployment plan metadata  POC: Jaiganesh Balasubramanian CoSMIC Tools: Deployment Planning (5/7)

8  CCMPerf is a model integrated test and benchmarking suite  Models application use-case scenarios to synthesize desired performance aspects of DRE applications  POC: Arvind Krishna CoSMIC Tools: Benchmarking (6/7)
