Platform Independent Models (PIM) and Platform Specific Models (PSM) of the application use cases into a production environment

This result represents the PIM and PSM mapping for the three use cases that have been prototypically implemented in the MODA-TEL project, namely:
- Voice applications based on VoiceXML, which aims at defining voice based telecom services in a platform independent model and provide the transformation to a platform dependent model based on the existing infrastructures at France Telecom and Telenor.
- A Quality of Service (QoS) aware video service, which aims at combining model driven development with aspect oriented modelling in order to augment an existing video service at T-Systems, with additional quality of service support.
- A Customer and service management use case based on the implementation of the specification of the Telecommunication Service Access and Subscription (TSAS) specification.

This result includes the applied steps, of an overall methodology being developed in MODA-TEL. These steps include the:
- Definition of a suitable meta model for the specific use case domain
- Definition a concrete notation for the PIM modelling
- Platform description defining the platform dependent meta-data
- Definition of a notation for platform specific models
- Definition of the overall transformation process
- Definition of PIM to PSM mapping rules
- Development of the code generator

For each of the use case this result covers specific requirements of the use cases and the concepts and methods adequate for implementing them. As a next step for each use case the platform independent model (PIM) is specified and covers the used meta-models, the notations and other methods relevant to the PIM development. After the PIM development step and in order to derive the platform dependent model (PSM) the platform descriptions, meta-data and notations for the specification of the PSM are specified. As a final step in the MDA trajectory the transformation rules are specified, including the mapping rules for the PIM to PSM transformations and the code generation.

A significant part of the result id knowledge about model transformation techniques. Model transformation is a development pattern explored extensively in MDA. A model transformation is the generation of one model from another model. More concretely transformations are performed at the level of the model elements of the source models and their corresponding model elements of the target model. For example in the context of telecoms design and specification languages (such as the ITU-T family of languages) provided that transformation rules are defined, these languages can be used in the context of MDA.
