A process library describes a system of activities with a well-contoured business function, which makes them suitable for sharing and reusability. You can find a more detailed approach on the subject on the About Libraries page in our Studio guide.
In Orchestrator, this functionality implies a centralized location where all libraries are stored, namely the Libraries page. From here libraries are shared across teams and tenants and can be used by any user who has access.
The Libraries page is the same for one Orchestrator instance, meaning libraries are not isolated at tenant level: each tenant has access to the other tenants' activity on this page.
Explicitly, on the Libraries page you can view and delete all the libraries that had been published from UiPath Studio, as well as those that were uploaded manually. There you can see the version of each package as well as release notes for each version, if any (should be added in Studio in order to better keep track of changes between versions).
Take into account that libraries and packages have the same set of permissions, namely the Packages permissions.
The default Libraries folder is
~/NuGetPackages/Activities. You can configure it in the
web.config file, by changing the value in the following element:
<add key="NuGet.Activities.Path" value="~/NuGetPackages/Activities" />
Libraries can only be published to Orchestrator v2018.3.
