RESTful webservices and zopeΒΆ
Articles like this one from Ryan Tomayko remind me that zope probably isn't too RESTful. (REST = xml_or_rdf combined with bare bones http). Tried it a year or so ago and it at least wasn't very easy.
On the other hand, the upcoming schooltool calendar release mentions a REST xml webservice interface. And schooltool is build on the newer zope3. So there's probably hope :-)
