How Applications/Components Communicate Within FASE INLINE PROFILE  Direct in-process communication Python applications with Python components Python applications with ANSI-C components through SWIG bindings SAMP PROFILE  IVOA SAMP messaging communication From any application to any component Embedded SAMP Hub and Package-Manager daemon L. Paioro - Python/C FASE prototype - Marseille, June 2010

Component-Container Model Components are wrapped by containers implementing a standard set of interfaces which connects them to any framework implementation compliant with the CCM standards Component-containers are packaged together in a standard format which enables them to be deployed within any framework implementation compliant with the packaging standards L. Paioro - Python/C FASE prototype - Marseille, June 2010

The Application Programming Interfaces System API  Shared by applications and computational components to perform generic access to the framework resources and services Component-Container API  Allows to implement a task or tool container and make it executable through the framework Application API  Provides proxies to the computational components in order to access and execute them through the framework L. Paioro - Python/C FASE prototype - Marseille, June 2010

System API (UML) Connect with the framework instance and return references to the main services Load the packages, query their capabilities and create new requests, responses and related psets Service for synchronous and asynchronous invocations Service for events notification and receiving L. Paioro - Python/C FASE prototype - Marseille, June 2010

Component-Container API (UML) Introspection capabilities Single atomic operation Task (IS one operation) and Tool (IS COMPOSED BY several operations) Single atomic operation I/O: -Parameter set -Job ID -Errors L. Paioro - Python/C FASE prototype - Marseille, June 2010

Component-Container API (UML) Collection of parameters Single parameter L. Paioro - Python/C FASE prototype - Marseille, June 2010

Application API (UML) Proxy to the package after loading, allows to get new tasks and tools instances ToolProxy allows to access tool operations and execute them (synch/asynch) TaskProxy to launch a task execution (synch/async) L. Paioro - Python/C FASE prototype - Marseille, June 2010
