Hi Jochen, the only thing I had in mind to achieve sth. like that is using a Camel route. There exists a WebDav and a CMIS Camel component. But I think you still have to implement a CMIS Server to provide the CMIS endpoint. This server then could use the (unofficial) WebDav component to fetch data from a WebDav Server (https://issues.apache.org/jira/browse/CAMEL-2331).
Far from an out-of-the-box solution ;) … Cheers Sascha
