[Zope-dev] [Checkins] SVN: zope.dublincore/trunk/ Renamed the ``zope.app.dublincore.*`` permissions to ``zope.dublincore.*`.

[Jacob Holm]

Hi Michael, Tres

I agree a new major version is required due to the new "feature" of
having new permission names, but there is no reason to break
compatibility with code using the old names.

IIRC the <redefinePermission/> zcml-directive  is there exactly to
provide backwards compatibility when renaming permissions.  Use like:

  <redefinePermission
      from = "<no longer defined permisison id>"
      to = "<existing permission id>"
      />

It is defined in zope.security:meta.zcml along with the <permission/>
directive, so should be usable with any code that uses that.


Best regards
