the gs representation can be whatever you want, registering an adapter
allows you to serialize content in whatever form is best for it.
contentsetup in plone svn uses marshall for example on at content, with
separate data file serialization for any file/image fields. for gs
default, dav was used primarily as canonical likley because it was easy as
already present generically on content implementations.

Hi,
What is the correct pattern for FTP representations of a CMF content
type? I am trying to create a content export/import mechanism for some
custom objects, but I've found a few different patterns to follow:
First of all, all content tries to use it's WebDAV representation. This
is good for links and documents because it captures all the properties
in one place. It's not so good for Files and Images because their
metadata doesn't get exported/imported at all.
Secondly, the types which export a full set of information implement
their own manage_FTPget methods which hard-code in the representation in
some way. Document uses aliases, but only if the content type is
text/html - if it is text/plain for example, aliases are bypassed. Link
doesn't use aliases at all, and News just does whatever Document does.
Thirdly, folders store the title and description in a .properties file.
The properties to be included in this file (title, description) are
specifically specified in the import/export adapter.
My questions are:
- what sort of pattern should be aimed for (ideally) here?
- should all the types use aliases to work out their DAV
representation or was this abandonded?
- are there any 'hidden' advantages of im-/exporters adhering closely
to the DAV views (as opposed to an im/export specific representation.
e.g. a binary file and associated .properties file)
- should each object's representation take care of including all the
required properties, or should there be some way of ensuring that all
common metadata (DC values) are treated via some sort of common route
Thanks,
Miles
