Roberto,

That wiki page is marked as "3.3". The old CMIS URL wasn't deprecated =
until 4.0.

I'm glad you found the official docs site.

Another resource you might want to know about is the CMIS alfresco forum =
[1]. If you have further issues that you think might be =
Alfresco-specific and you want to bounce some ideas around, feel free to =
join us there. (This list is a great resource too, I'm just adding to =
your list).=20

Jeff
