Hi Philippe,

Thanks for the questions.

Q The goal of NGOSS is to define models and interfaces between OSS and 
BSS components. Are these interfaces specified ? in the process of being 
specified ?

A The TM Forum Interface Program TIP is defining the interfaces. The 
team is drawing from the base of OSS/J and MTOSI to come up with a 
unified interface standard. Presently the focus is on using SOAP over 
HTTP and over JMS. These interfaces would effectively be used to 
implement  'NGOSS Contracts' between OSS systems. You can only get 
involved in the standardisation process if you are a member of the TM 
Forum. However as Bull are members of the TM Forum, you would be very 
welcome to get involved directly in the TIP program. See 
http://www.tmforum.org/InterfaceProgram/5733/home.html 

Q What is exactly the goal of openoss ? implement these interfaces as 
abstract java classes ?

There are three main goals for OpenOSS.

Firstly to support the creation of the 'TIP Framework'. The design of 
the TIP Framework is being led by Jerome Magnet of Nortel Networks and 
will  encapsulate the core design patterns and supporting tool chain 
which take the TM Forum SID model as a starting point for defining 
interface specifications. Each specification design team will combine 
end user business cases with information models derived from the SID in 
order to specify a particular interface. They will then use the TIP 
Framework as tooling to help their task. Work in progress include a 
Service Problem Management Interface, a Resource Problem Management 
interface and an Inventory interface.

Relevant facets of the SID model will be ported to a model supported by 
the Eclipse Tigerstripe project http://www.eclipse.org/tigerstripe/ 
where various 'Plugins' are used to generate documentation XSD's and 
WSDL corresponding to the design of each interface. The output from this 
process will represent the TM Forum Specification of a given interface. 
OpenOSS will provide open source hosting for the development and testing 
of the TIP Framework plugins. We believe these tools will have wider 
industry use beyond just the needs of the TIP program.

Secondly, It is intended to provide a framework for rapidly implementing 
Compatibility Test Kits (CTK) and Reference Implementations (RI) for 
each specified interface. We want to use the model in Tigerstripe to 
generate as much of the RI code as possible and significantly speed up 
the development process for the RI and CTK which are essential 
deliverables for each standard specification and currently take a great 
deal of manual effort. There will still be manual effort required but we 
believe that the model driven engineering approach will greatly speed up 
the process.

Finally, as part of the RI and CTK work, we also want to deliver 
libraries and example code which will greatly help potential 
implementers of the TIP interfaces. These libraries would be delivered 
as Apache 2 licensed open source. The intention is to speed up the time 
to market for the adopters of the interfaces and avoid some of the 
pitfalls which previous TM Forum interface efforts have experienced 
where the lack of support for implementation has prevented mass uptake 
of the standards by SI's and service providers.

We are implementing the RI /CTK and TIP library using Java. However the 
Java API for the library will not (currently) be subject to 
standardisation. It will be a de-facto standard for this particular 
implementation library which adopters of the standard can use if they 
choose. One thought is that this could be extended to provide a next 
generation definition for OSS/J but this is not currently a stated 
design goal.

I hope this helps

Craig
