+zopyx.versioning
+================
+
+```zopyx.versioning`` is a generic versioning system for schema-oriented
+content-objects (zope.schema, Archetypes, Dexterity etc.).
+
+
+Basic concepts
+--------------
+
+- pluggable storage API (storing the versioned data)
+
+- using JSON as data exchange format between objects to be versioned 
+  and versioner and between versioner and backend storage (the storage
+  may use a different serialization format (e.g. 'pickle' for a ZODB
+  based backend or 'json' for a typical noSQL backend like MongoDB)
+
+- making use of the Zope Component Architecture for adopting arbitrary 
+  content objects to the storage API
+
+- the solution does not claim to store and restore the complete state of
+  an content object. Instead we focus on dealing with the metadata and
+  the content itself. If an object uses a complex internal data model then it is
+  in responsible to serialize and deserialize the data to JSON.
