CMIS 1.1 introduces a number of new concepts that are supported by Alfresco. You can now use the new browser
binding to simplify flows for
web applications, use Alfresco aspects, and use the append data support to manage large items of content.
The Browser binding
Alfresco aspects are exposed as secondary types in CMIS 1.1. You can dynamically add aspects to an Alfresco object using the API.
In some applications such as journaling, or when using very large files, you want to upload a file in chunks. You might have large files that time out during an upload, or fail because of a bad connection. You can use the CMIS 1.1 append parameter in these situations
You can use cmis:item to query some Alfresco object types and your own custom types that are outside the CMIS definitions of document, folder, relationship, or policy.
