Ron Gavlin commented on CMIS-818:
---------------------------------
I was thinking the LastModifiedObjectInFolderContainerList interface might have
a boolean ifModifiedSince() method to indicate SC_NOT_MODIFIED 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 not
SC_NOT_MODIFIED. This is clearly not as clean as the LastModifiedContentStream
handling but seems doable.
> Navigation services should support Last-Modified/If-Modified-Since Headers

> 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.
