[Zope-CMF] Anonymous submissions -- Some advice?

[Ricardo Newbery]

I'm still feeling my way around CMF and learning new tricks every 
day.  There's nothing like a real project and a deadline to give you 
some motivation.

Anyway, I would like to create a special skin to facilitate a 
semi-anonymous submission of certain file objects and I could use 
some advice.


The proposed workflow...

1) A special 'user' is predefined and given the Member role.  Let 
name the user, 'public'.

2) An anonymous user visits a page similar to the 'folder_factories' 
skin but with only two inputs: a dropdown select list of county names 
and a text input field for the user's email address.

3) After submitting this form, the email address is validated and the 
object 'id' would be generated from the county name and a timestamp, 
then an upload form is presented similar to the 'file_edit_form' skin.

4) Uploaded files would be deposited within the 'public' member 
folder and owned by 'public' and automatically submitted for review.

5) After successfully uploading a file, a confirmation message is 
sent to the submitted email address and a list of contact addresses 
maintained in a TinyTable file.


Okay, now for the questions...

1) Before I go any deeper, are there any obvious problems with this 
proposed workflow?  Is there an easier way I'm missing?

2) It is unclear to me exactly where to insert the 'id' generating 
code.  I'm guessing that I might need to have the first form submit 
its data to a 'generate_id' skin which would then call the 
'invokeFactory' method.  I believe this method then returns the skin 
defined for that object type (I'll define a special file type for 
this purpose).  Does this sound right?  And how exactly should I call 
the 'invokeFactory' method from the skin?

2) How do I tell the skin to use the 'public' folder when uploading 
the file and assign the correct ownership?

3) I would like to save the submitted email address as metadata for 
this file.  How do I define additional metadata fields for this 
object?  Remember, I'm a Zope/CMF newbie.  ;-)

4) The confirmation emails will have a special return address for 
responses.  I would like to create a log of return emails for each 
file.  I'm currently looking at POP Mail Zope Product for ideas here. 
Any suggestions are appreciated.
