Re: [fractal] Re: [architecture] Fractal packaging & deployment,bis

Hi,

The CORBA Component Model deals with heterogenous
components e.g. implemented in different programming
languages like C++, Java, etc. In this model, deployment
units are called Component and Assembly Archives, CAR and 
AAR files respectively. These files are ZIP files.

A CAR is the deployment unit for only one component type
but could contain several implementations with several 
associated meta data, eg. one implementation in Java and
one implementation in C++ for Windows and one implementation
on C++ for Linux X.Y.Z, etc.

An AAR is the deployment unit of a set of assembled components
and could refer to or embed several CAR files.

This is just to propose that 'Fractal deployment units'
could be called 'Fractal archives' independently of these
contents. Then we could speak about:
* instances :       components seen as runtime units
* archives  :       components seen as deployment units
* implementations : components seen as development units
* types :           components seen as design units

This could avoid us to reuse fully words like 'seed', 'germ',
or 'bundle'.

A+
