[entity] introduce a new 'adapters' registry This changeset introduces the notion in adapters (as in Zope Component Architecture) in a cubicweb way, eg using a specific registry of appobjects. This allows nicer code structure, by avoid clutering entity classes and moving code usually specific to a place of the ui (or something else) together with the code that use the interface. We don't use actual interface anymore, they are implied by adapters (which may be abstract), whose reg id is an interface name. Appobjects that used to 'implements(IFace)' should now be rewritten by: * coding an IFaceAdapter(EntityAdapter) defining (implementing if desired) the interface, usually with __regid__ = 'IFace' * use "adaptable('IFace')" as selector instead Also, the implements_adapter_compat decorator eases backward compatibility with adapter's methods that may still be found on entities implementing the interface. Notice that unlike ZCA, we don't support automatic adapters chain (yagni?). All interfaces defined in cubicweb have been turned into adapters, also some new ones have been introduced to cleanup Entity / AnyEntity classes namespace. At the end, the pluggable mixins mecanism should disappear in favor of adapters as well.

This web application is based on the CubicWeb knowledge management system

     5

from Logilab_. CubicWeb is made of an object database and a web

     6

framework. It allows to develop an application by defining a set of

     7

entities and their relationships, plus a set of views that present the

     8

data selected from the object database using a specific query language.

This application has a precise schema_ and can be considered an

    11

example of a semantic web database, as it can export the data to XML

    12

and others formats and is not limited to publishing HTML.
