Description

I have implemented a ResourceProvider, which allows to create symlink nodes in the JCR repository. A symlink node has a sling:symlinkTarget property, which should contain a valid JCR path. JCR content from the sling:symlinkTarget path is then exposed below the symlink node.

There is a mixin node type, sling:Symlink with a mandatory property sling:symlinkTarget and an optional property sling:overlayable. Additionally, there is a convenience node type, sling:SymlinkResource, which extends from sling:symlinkTarget and nt:unstructured.

ResourceProvider instances are registered for existing symlinks when the bundle is started. Modifications are taken care of via JCR observation.

To get started:

• apply the attached patch to a trunk checkout
• build and install the bundle
• create a symlink node, pointing to some existing content
• access the symlink node e.g. via a browser
