Hello,
After rethinking my data-model, the pieces start to fit for me. I was trying too much to reuse my original data-model, which consisted of unversioned data in tables, linked together with foreign keys. Using the CR correct, and restructuring my data in a hierarchy using content-item's parent_ids (and relations to do more advanced linking), I'm now able to do the same without giving up on the constraints I need...
Lesson learned. While trying to migrate my old system to use the content-repository, I focused too much on my old data-model while I needed a slighty different mindset for this.
thanks everybody
greetz,
