CMIS is a protocol with several optional bindings: Atom, WSDL, Browser.
According to Alfresco's documentation:
Currently Alfresco supports the atom binding for the CMIS 1.0 protocol,
and both the atom and browser bindings for the CMIS 1.1 protocol.
In fact, Alfresco also has a (undocumented?) WSDL binding for CMIS 1.0 at URL http://server/alfresco/cmisws/cmis?wsdl
.
Similarly, is there a WSDL binding for CMIS 1.1, and if yes, at what URL?
I have tried http://server/alfresco/api/-default-/public/cmis/versions/1.1/wsdl
and many similar URLs but no luck so far.
