Requirements

The DAM will have a concept of originals, where the asset you upload is kept as an original that you can revert back to later on.

Alternative 1 - Separate workspaces

Assets in one workspace, originals in another.

Alternative 2 - Separated by path

Assets under /assets and originals under /originals

Alternative 3 - Mixed in the same tree

Since an asset refers to exactly one master we could have a tree of folders and originals with the assets as sub nodes of the original.

Additionally

Q: What is the id of an original? Is it important at all?

Q: How do we create a hierarchy of originals? We want to avoid a flat structure in JCR
