I've got a requirement to make uploading of some special pdfs easier and

My thoughts are to allow upload via webdav or FlashUpload and then use a
custom workflow ensure all the new metadata is filled out.
It appears I can achieve this via
a) Create a new archetype based on ATFile with extra fields
b) Create a new archetype with an AttachmentField
c) Adapt the existing ATFile object to add the new metadata using
schemaextender.
I'm not sure of all the implications of each option.
option c seems good because I can then use ARFilePreview right?
and what are the implications if I wanted to use some external storage?
How local is SchemaExtender changes?
SchemaExtender applies to interface (possible also o classes).
Not sure if it would be possible to attach a marker interface to
particular instances and then having an extender registered for this
particular
marker interface...try it out.

Yes, that is possible. You can have schemaextender react on a marker
interface as well. I do that in slc.publications which you can find in
the collective.
