[TransWarp] SkinScript-to-Jars phrasebook, deleting objects, and terminology

... after reading hours :)

as far as i understand your concepts, i like them ...

i have a few questions:

will it be possible to "transparently" change storage jars,
without modifying Elements that use it ??? so one could
switch between ZODB-storage jar and sql-st.jar (thinking
of query-issues and oid-incompatiblities,different name-mappings)

is a query-jar also for retrieving obj.ids (e.g. a list of
person-oids), and will it implement native-filters or
a unified (OQL-like) QL ??

a DataLayer definition would look similar to the
current as done in DataModel? (don't count on the
class-names .. just my imagination :)

e.g.
class MyStorage(storage.persistent):

  class Users(DataManager):
    .
    some dm-attrs here
    .
    class User(State):
      .
      some state-attrs here
      .


or it is loaded via xml/etc config .. am I right ??

with naming i'm unsure as well ..
I basically like the idea, that a Specialist has a DataManager 
(storage-jar).
I can image to load a State from a DataManager, but i have no idea how
to call query-jars etc ...

peak.storage is fine with me and i like that storage relevant things will
go there.
