=== PRCS major version  ===

'''oln.2003paradigm'''

prcs checkout -r2003paradigm oln

=== Done ===

* Transition to the Exact static hierarchy
* New modeling (core)
* clean directories and related tests:
** arith: {{PrintAuthor|Sylvain Berlemont}} '''done'''
** convert: {{PrintAuthor|Reda Dehak}} '''done'''
** convol: {{PrintAuthor|Astrid Wang}} '''done'''
** core: {{PrintAuthor|David Lesage}} and {{PrintAuthor|Nicolas Burrus}} '''done'''
** doc: {{PrintAuthor|Giovanni Palma}} and {{PrintAuthor|Nicolas Burrus}} '''done'''

** topo: {{PrintAuthor|Sylvain Berlemont}} '''done'''
** transforms: {{PrintAuthor|Reda Dehak}} '''done'''
** utils: {{PrintAuthor|Sylvain Berlemont}} '''done'''

=== TODO ===

* Coding style: {{PrintAuthor|David Lesage}} & {{PrintAuthor|Nicolas Burrus}}: '''nearly done'''

* iterators on data
** should be added in image_impl interface
** usage: <pre> abstract::image<E>::impl_fwd_iter_type it(ima); for (it = begin; it != end; ++it) std::cout << *it; </pre>

=== HowTo clean a directory ===

* the aim is to make it '''check'''
* associated tests (olena/tests) must be adapted

* things to take care about
** includes: some files have disappeared: ex: core/internal/*image*.hh, core/border*.hh. Please refer to the documentation and/or {{PrintAuthor|Nicolas Burrus}} & {{PrintAuthor|David Lesage}}.
** ExactCref: they '''must''' disappear. Take also care about template parameters that should not have the "underscore" style anymore.
** Borders operations: there is no namespace "border" anymore. All these operations are now image member functions. 
** For any question about the new modeling, please refer to the documentation and/or {{PrintAuthor|Nicolas Burrus}} & {{PrintAuthor|David Lesage}}.

	'''Image Hierarchy Modeling'''

* Adding a new '''discriminant''': one related to the way the object is stored in memory. It allows having dense/sparse images, for example, represented differently in memory. Maybe taking a few ideas from vaucanson is a good thing ? (i'm thinking of the 'Element' model) Plus, this model can include function images, as well, thus leading us to a 'Unified Model'. -- {{PrintAuthor|Youssef Elfassyfihry}}
