----------------------------------------------------------
I was thinking the LastModifiedObjectInFolderContainerList interface might have
a boolean ifModifiedSince() method to indicate the SC_NOT_MODIFIED/OK state and
that the service, based on its own SC_NOT_MODIFIED check, would either: a).
return an empty list along with ifModifiedSince() equals false if
SC_NOT_MODIFIED or b). return a populated list with ifModifiedSince() equals
true if OK. Here, the service interrogates the request headers and the caller
sets the response header and status code. This is clearly not as clean as the
LastModifiedContentStream handling but seems doable.

> Key: CMIS-818
> URL: https://issues.apache.org/jira/browse/CMIS-818
> Project: Chemistry
> Issue Type: Improvement
> Components: opencmis-server
> Affects Versions: OpenCMIS 0.11.0
> Reporter: Ron Gavlin
> Assignee: Florian Müller
>
> AtomPub and Browser navigation services including getChildren, getFolderTree,
> getDescendants, and potentially the others should support
> Last-Modified/If-Modified-Since Headers.
> Some repositories have built-in caching mechanisms to track whether a folder
> tree has been modified. Since many of the Navigation services often require
> significant server-side resources, repositories with these built-in caching
> mechanisms should be able to leverage them with OpenCMIS. Currently, the
> OpenCMIS NavigationService does not provide hooks to implement such
> optimizations.
