Can Nuxeo DM and Nuxeo DAM run jointly?
If I want to use Nuxeo DAM and Nuxeo DM, can I have both of them running on the same installation and same content repository? Will they share the same users and documents?
Yes and yes.
In a shared repository scenario documents can be created in either of those systems and previewed/manipulated in the other.
The users can be set up in the same database.
Please note that user authentication can also be done via a third-party system or protocol (e.g. LDAP, ActiveDirectory, OpenAuth, etc), while documents can be accessed from other systems, too (WSS Share Point, WebDav, etc).
Don't they HAVE to run together to have any management posibilities?
If only DAM exists there is NO way (that I can see) to do anything with folders (ie delete) from DAM tab, but only from DM tab
Same applies to group rights (they can only be managed on DM tab)
