Hello,
I've implemented it now, but I get the following error when I try to change or 
add a new ILink.
I'm logged in as zope.Manager.

My configure.zcml:

    <adapter
        for=".link.Link"
        provides="zope.app.dublincore.interfaces.IZopeDublinCore"
        factory=".link.factory"
        />

My link.py:

[...]
from zope.app.dublincore import annotatableadapter

factory = annotatableadapter.partialAnnotatableAdapterFactory(["description"])

the description field is defined in the interface:

    description = TextLine (
        title = u"Description",
        description = u"Description which mirrors the DC metadata.",
        required = False)

What is wrong there?

Thanks,

Florian
