A quote from [2]:

"I’m pleased to announce that we have Released to Web, the Content Management Interoperability Services (CMIS) Connector for SharePoint.  The CMIS Connector for SharePoint ships as part of the SharePoint 2010 Administration Toolkit, providing a CMIS interface over the top of SharePoint as well as a CMIS Consumer Web Part that can be used to display content from other CMIS enabled repositories."

With this step SharePoint integration in an AxCMS.net project gets easier. CMIS domain model fits well into AxCMS.net model and WebServices (one of the two CMIS-bindings) are easy to consume from out AxCMS.net.
