Ken Baclawski commented on CMIS-786:
------------------------------------

I have posted another version of the proposal for a symbolic link in https://www.oasis-open.org/apps/org/workgroup/cmis/download.php/57768/symbolicLink.docx

This proposal includes the changes that were suggested in past meetings.  It is a proposed optional extension to CMIS 1.1.  If it is going to be incorporated into CMIS 1.2, then there may better ways to deal with the problem of disabling dereferencing than that used in the current proposal.

> This extension provides for a subclass of cmis:item called cmis:symbolicLink.  An object of type cmis:symbolicLink has an attribute referenceId that specifies an object Id or latest accessible state identifier.  When the Id of a  symbolic link item is specified in a service request, the referenceId attribute of the item may be used instead of the specified symbolic link Id.  The replacement of the symbolic link Id with another Id is called dereferencing.  When dereferencing is performed, it is recursive: if the referenceId of a symbolic link item is itself the Id of a symbolic link item, then that symbolic link Id is also dereferenced.  If a dereferencing cycle is detected, a cmis:dereferenceException is thrown.  Dereferencing of symbolic links in a service call can be explicitly enabled or disabled by an optional dereferenceSymbolicLinks parameter.  If the dereferenceSymbolicLinks parameter is not specified as FALSE in a service call, then symbolic link dereferencing is performed, i.e., the default value of the dereferenceSymbolicLinks parameter is TRUE.
