That means every ATFile in the system will have those new fields right?
It's not essential that all ATFiles have those fields. For example, for
a PloneGetPaid project, I created a schemaextender
subclass IRichDocumentDecorator to add fields to a RichDocument, IF they
provide IShippableMarker:
<adapter
provides=".interfaces.IRichDocumentDecorator"
for="Products.PloneGetPaid.interfaces.IShippableMarker"
factory=".browser.storeitemdecorator.RichDocumentDecorator" />
You could mark your type at the time you handle the upload, once you
have inspected the file type. Rocky began doing this 18 months ago in
Plone4Artists, which has probably moved further along this path.
Is that what the subtype menu does in p4a, just set a marker interface?
Seems like schemaextender is the way to go.
