Predefined views in the library
-------------------------------

A certain number of views are used to build the web interface, which apply
to one or more entities. Their identifier is what distinguish them from
each others and the main ones are:

:primary:
    primary view of an entity, this is the view called by default when a single
    entity is in the result set and needs to be displayed. This view is supposed
    to render a maximum of informations about the entity.
:secondary:
    secondary view of an entity. By default it renders the two first attributes
     of the entity as a clickable link redirecting to the primary view.
:oneline:
    similar to the `secondary` view, but called when we want the view to stand
    on a single line, or just get a brief view. By default this view uses the
    parameter `MAX_LINE_CHAR` to control the result size.
:text:
    similar to the `oneline` view, but should not contain HTML.
:incontext, outofcontext:
    similar to the `secondary` view, but called when an entity is considered
    as in or out of context. By default it respectively returns the result of 
    `textincontext` and `textoutofcontext` wrapped in a link leading to 
    the primary view of the entity.
:textincontext, textoutofcontext:
    similar to the `text` view, but called is an entity is considered out or
    in context. By default it returns respectively the result of the 
    methods `.dc_title` and `.dc_long_title` of the entity.
:list:
    creates a HTML list (`<ul>`) and call the view `listitem` for each entity
    of the result set
:listitem:
    redirects by default to the `outofcontext` view
:rss:
    creates a RSS/XML view and call the view `rssitem` for each entity of
    the result set
:rssitem:
    create a RSS/XML view for each entity based on the results of the dunblin core
    methods of the entity (`dc_*`)

Start view:

:index:
    home page
:schema:
    display the schema of the application

Special views:

:noresult:
    called if the result set is empty
:finall:
    display the value of a cell without trasnformation (in case of a non final
    entity, we see the eid). Applicable on any result set.
:table:
    creates a HTML table (`<table>`) and call the view `cell` for each cell of
    the result set. Applicable on any result set.
:cell:
    by default redirects to the `final` view if this is a final entity or
    `outofcontext` view otherwise
:null:
    view always applicable and which does not return anything
