I have to store many XML documents recognized with a unique title, and keep an eye on their versions. I have to come with an use of every document (read, update, remove) through some Peaceful API. I have to maintain access control (read/write permissions) for each document (or categories of them).
Can there be any solution available on the market of these needs?
Btw, other extra features could be welcome, like XSD-validation of each and every new incoming change.
