Not to derail anything but I feel your pain
@Lumber, but for different reasons, having had to use RDIMS on and off over a decade.
Not only is the access a challenge, but there are multiple libraries, and you typically don't have access to the ones you need. For example, CRCN, MEPM and the PMOs all have their own libraries, so not uncommon to have the original of a file on one RDIMS library, and multiple copies on other libraries (under their own unique numbers).
The file plan very broadly follows the military file plan from memos, but things get logged wherever it makes sense to the user, and they can set unique access restrictions for each file.
It also has an interceptor so every time you go to open/save a file in the office suite and some other program it jumps to RDIMS, and that frequently freezes and glitches because it's windows 98 program with a lot of kludges.
I dislike it slightly more than DRMIS to give you an idea; it definitely logs documents, but I would say 'management' is a stretch. It's really easy to lose something in the digital ether there and then never find it again. If someone ever says to you in a turnover 'its all in RDIMS', laugh then make them send you all the links and make sure you have the permissions to files you need to read/edit.
