The motivation for theh partial adapter was that for some content, some of the data fields correspond directly to DC elements. For those, we wanted the DC adapter to use the fields instead of storing the information outside the object. When defining our content types we almost always end up with properties which are already defined in Dublin Core. Also the Dublin Core implementation of Zope 3 gives us a lot of meta data for free. Dublin Core has the advantage that the access to common information is standardized but it is not as easy to access DC meta data as it is to access a simple property of the content type. So we decided to have the advantage of Dublin Core and the advantage of simple property access in one.

Quote from zope/dublincore/tests/partial.txt which describes the partialAnnotatableAdapterFactory: Sometimes we want to include data in content objects which mirrors one or more Dublin Core fields. In these cases, we want the Dublin Core structures to use the data in the content object rather than keeping a separate value in the annotations typically used. What fields we want to do this with can vary, however, and we may not want the Dublin Core APIs to constrain our choices of field names for our content objects. Should the partialAnnotatableAdapterFactory therefore be removed/deprecated?
