Hi Idan,

Field level information is stored in OpenJPA's FieldMetaData or FieldMapping
(a subclass of FieldMetaData) objects.  FieldMetaData extends an abstract
class org.apache.openjpa.meta.Extentions.  While I've never used Extensions,
it looks like you could parse out your specific annotation in the annotation
parser and set a value in the FieldMetaData as an extension.  Then,
depending on the method you are overriding, you may be able to get access to
the FieldMetaData/FieldMapping and its extension(s) within your custom
