I have done some searches and analysis, and have not been able to locate any sort of web-based online collaboration feature for documents. I am looking for a feature similar to that of Google Docs or similar services.
I would like to be able to do the following, once a file is uploaded:
- Allocate permissions (View, edit, none, et. al)
- Log changes (Admin feature - who, when, and what they changed)
- Allow query-based permissions (For example, if I update an XLS file, I would like to use a master file, which shows all projects, but would want to limit access to particular individuals so they can only view or edit projects they are assigned to in a particular column). This would sort of be like saying, "If cell A1=Joe,allow read/write, otherwise no privelages).
Any feedback would be very greatly appreciated. This is a very important feature for me to research.
