zope.annotation API

Framework Interfaces

These interfaces define the source and targets for adaptation under the zope.annotation framework:

Annotations store arbitrary application data under package-unique keys.

Attribute-Based Annotations

The default adapter implementation uses a special attribute, __annotations__, on the annotated object:

class zope.annotation.attribute.AttributeAnnotations(obj, context=None)

Store annotations on an object

Store annotations in the __annotations__ attribute on a IAttributeAnnotatable object.

Because setting an attribute is somewhat intrusive (as opposed to storing annotations elsewhere), this adapter requires that its context implment zope.annotation.interfaces.IAttributeAnnotatable to signal that this attribute can be used.
