[EP-tech] Re: Is eprints multitenant?

Hi Karlo,

As Paolo pointed out - the repositories would share the base and default configuration files and scripts and plug-ins, but these can then be over-ridden and configured separately for each repository to give them their own individual front-end look and feel and functionality, and the back end databases would be completely separate, with separate user tables (controlling the repository administrators and users), and SQL connection ids.

Obviously, the server administrators and DB administrators would have access to the underlying code and databases for all the repositories running on the same hardware.

(oralhistory.open.ac.uk could be a routing issue - it's fine from this side of the firewall - I'll get someone to look.)

Regards,
Alan

Dear Alan,

this is exactly what I have asked for.

White Rose is de facto one IR and the three universities are technically
like e.g. three departments, which is OK for White Rose.
But this is *not* what I want.

My library serves three different institutions (in the legal /corporate
sense), where one institution wants an IR *now*, and the two other perhaps
some day.
If they also want one, it would be then possible to take the *same*
installation (same "bits of hardware"), but a very different backend (e.g.
administrators) and frontend (e.g. deposit-IDs or the mere design of the
search interface).

BTW: http://oralhistory.open.ac.uk seems to be unavailable.

Thanks to all!
Best,
Karlo
