As far as I know Alfresco Community Edition (LGPL v.3), LogicalDoc CE (LGPL v.2) and a whole bunch of DMS are Open Source , if CentOS package is available, I’m not sure. But I have read both requires Java/TomCat bundles. I’ve just set both as an example as those are the ones which might have been popular in their fields.
I just want to add, feature such as Access Control and work-flow would be nice as well as OCR recognition.
Now now now, let’s not get carried away, I know we have limited resources…again, just thinking out loud that these would be nice to have. Its not in a hurry and no expectation.
Thanks @alefattorini, I had not searched in the forum…just browsed if DMS is included in NS features/modules. Be forwarned though, I have tested Alfresco Share (5.0.d) in a virtual environment (not NS) and it seems a hungry beast, it needs atleast 2GB of RAM else the installation will not push through, but it seems to be one of the better DMS out there.
i Would say a sas/iscsi support inbuild for expansion of owncloud,roaming profiles info, for rapid redundancy and availability, a module that permit attach a custom iscsi disk or partition for that data only.
because the VM aproach for Owncloud and roaming profiles is to expensive, i would prefer throw that data to a inexpensive and SAS or isci devices for better backup/data/price performance and the Nethserver in a VM inself.
