Hi,
I've written a sample application for Sling which is a nice photo
gallery (I'm planing to commit this as a sample in Sling).
Obviously the app acts on images. For better separation and managing the
data, the images are stored in folders under a root folder ("myapp").
I've wrapped my head around the problem of how to detect the correct
resource type for the images stored there for several weeks now :(
In order to be displayed correctly, each folder needs an album resource
type and each image a photo resource type. This can be done by observing
"myapp" and adding the properties to the corresponding files and folders.
But for one I don't like to use observation just to add a resource type
and secondly this only works if all your data is in the repository. With
Sling we have the nice resource abstraction. And I could just mount a
folder from my file system at myapp/myimages. And there is no way of
adding a resource type to those files.
For the jcr resource provider we have the JcrResourceTypeProvider
interface which allows to implement a custom resolution mechanism for
JCR content.
So one solution to my problem would be to make this interface more
general and I could implement something like the path based resource
type provider: if path starts with /myapp and extension is an image
extension -> resource type photo. No extension -> resource type is an
album. Or something along these lines.
Now I'm wondering if this is the way to go, or if there maybe is a
better approach?
