I would love to but unfortunately
I am not a developer but only a user looking for a Document Management System using SVN.
I feel the file storage and automatic versioning provided by SVN is great and there is no need to re-invent the wheel.
Head table would be needed anyway to generate statistics and other meta data.
Not sure what is your road map.
Interesting. I think the current file head data table is important which can be used for purpose of analysis and Statistics. But for your question, there is a file storage API (IFileStorageApi) to write/read physical file
stream. Maybe you can implement another class to write/read file stream against SubVersion so that we can get the file versioning without adding more data tables. And you're welcome to share the implementation with us then it would be released in the later
version of RapidWebDev.
