-The Registry, selectors and application objects
-===============================================
-
-This chapter deals with some of the  core concepts of the |cubicweb| framework
-which make it different from other frameworks (and maybe not easy to
-grasp at a first glance). To be able to do advanced development with
-|cubicweb| you need a good understanding of what is explained below.
-
-This chapter goes deep into details. You don't have to remember them
-all but keep it in mind so you can go back there later.
-
-An overview of AppObjects, the VRegistry and Selectors is given in the
-:ref:`VRegistryIntro` chapter.

-Base predicates
----------------
-
-Predicates are scoring functions that are called by the registry to tell whenever
-an appobject can be selected in a given context. Predicates may be chained
-together using operators to build a selector. A selector is the glue that tie
-views to the data model or whatever input context. Using them appropriately is an
-essential part of the construction of well behaved cubes.
-
-Of course you may have to write your own set of predicates as your needs grows
-and you get familiar with the framework (see :ref:`CustomPredicates`).
-
-Here is a description of generic predicates provided by CubicWeb that should suit
-most of your needs.
-
-Bare predicates
-~~~~~~~~~~~~~~~
-Those predicates are somewhat dumb, which doesn't mean they're not (very) useful.
-
-.. autoclass:: cubicweb.appobject.yes
-.. autoclass:: cubicweb.predicates.match_kwargs
-.. autoclass:: cubicweb.predicates.appobject_selectable
-.. autoclass:: cubicweb.predicates.adaptable
-.. autoclass:: cubicweb.predicates.configuration_values
-
-
-Result set predicates
-~~~~~~~~~~~~~~~~~~~~~
-Those predicates are looking for a result set in the context ('rset' argument or
-the input context) and match or not according to its shape. Some of these
-predicates have different behaviour if a particular cell of the result set is
-specified using 'row' and 'col' arguments of the input context or not.
-
-.. autoclass:: cubicweb.predicates.none_rset
-.. autoclass:: cubicweb.predicates.any_rset
-.. autoclass:: cubicweb.predicates.nonempty_rset
-.. autoclass:: cubicweb.predicates.empty_rset
-.. autoclass:: cubicweb.predicates.one_line_rset
-.. autoclass:: cubicweb.predicates.multi_lines_rset
-.. autoclass:: cubicweb.predicates.multi_columns_rset
-.. autoclass:: cubicweb.predicates.paginated_rset
-.. autoclass:: cubicweb.predicates.sorted_rset
-.. autoclass:: cubicweb.predicates.one_etype_rset
-.. autoclass:: cubicweb.predicates.multi_etypes_rset
-
-
-Entity predicates
-~~~~~~~~~~~~~~~~~
-Those predicates are looking for either an `entity` argument in the input context,
-or entity found in the result set ('rset' argument or the input context) and
-match or not according to entity's (instance or class) properties.
-
-.. autoclass:: cubicweb.predicates.non_final_entity
-.. autoclass:: cubicweb.predicates.is_instance
-.. autoclass:: cubicweb.predicates.score_entity
-.. autoclass:: cubicweb.predicates.rql_condition
-.. autoclass:: cubicweb.predicates.relation_possible
-.. autoclass:: cubicweb.predicates.partial_relation_possible
-.. autoclass:: cubicweb.predicates.has_related_entities
-.. autoclass:: cubicweb.predicates.partial_has_related_entities
-.. autoclass:: cubicweb.predicates.has_permission
-.. autoclass:: cubicweb.predicates.has_add_permission
-.. autoclass:: cubicweb.predicates.has_mimetype
-.. autoclass:: cubicweb.predicates.is_in_state
-.. autofunction:: cubicweb.predicates.on_fire_transition
-
-
-Logged user predicates
-~~~~~~~~~~~~~~~~~~~~~~
-Those predicates are looking for properties of the user issuing the request.
-
-.. autoclass:: cubicweb.predicates.match_user_groups
-
-
-Web request predicates
-~~~~~~~~~~~~~~~~~~~~~~
-Those predicates are looking for properties of *web* request, they can not be
-used on the data repository side.
-
-.. autoclass:: cubicweb.predicates.no_cnx
-.. autoclass:: cubicweb.predicates.anonymous_user
-.. autoclass:: cubicweb.predicates.authenticated_user
-.. autoclass:: cubicweb.predicates.match_form_params
-.. autoclass:: cubicweb.predicates.match_search_state
-.. autoclass:: cubicweb.predicates.match_context_prop
-.. autoclass:: cubicweb.predicates.match_context
-.. autoclass:: cubicweb.predicates.match_view
-.. autoclass:: cubicweb.predicates.primary_view
-.. autoclass:: cubicweb.predicates.contextual
-.. autoclass:: cubicweb.predicates.specified_etype_implements
-.. autoclass:: cubicweb.predicates.attribute_edited
-.. autoclass:: cubicweb.predicates.match_transition
-
-
-Other predicates
-~~~~~~~~~~~~~~~~
-.. autoclass:: cubicweb.predicates.match_exception
-.. autoclass:: cubicweb.predicates.debug_mode
-
-You'll also find some other (very) specific predicates hidden in other modules
-than :mod:`cubicweb.predicates`.
