<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D">Hi Chris,<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D">It’s not exactly that you would have separate installations of ArchivesSpace with the current multi-tenant approach, since the tenants share the same ArchivesSpace
core code. But you would have separate MySQL databases for each tenant. So by default, I *<b>think</b>* that this means that you would indeed have a separate public interface for each and every tenant.
<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D">That said, I’d say that our goal is to pursue a multi-tenant approach that uses a shared database. If that isn’t feasible, we might still go with a multi-tenant
installation that uses separate databases. <o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D">The use case for multiple tenants is very similar to why you’d use multiple repositories (and a few of our “tenants,” if not all, might still have multiple
repositories). The difference, as I see it, is that with multiple tenants you would have more control over the data (e.g. you could share all the name records across all of the repositories, as is the default AT/ASpace set up, or you could make those name
records tenant-specific) and how the application is extended (e.g. one tenant could use a plugin that’s specific to born-digital workflows, which could be suppressed from view for other tenants who might not need that functionality yet).<o:p></o:p></span></p>
