Introduction

The Data Repository is a software component that manages an RDF database and makes it available to other applications through a REST API, and gives end users specific views of the data. It adds role-based access control of varying granularity, transactional editing, custom treatment of ontologies and minimal/fast inference, and various administrative functions on top of the RDF database.

As of the MS6 release, you can use the new Export/Import service to create user accounts automatically (e.g. on a newly-created repository). This is NOT the same thing as true backup and restore; rather, it is intended more for setting up a test environment. The export and import services are very complex and powerful. This only gives one small example of what they can do. For all the details, see their entry in the API Manual.

Step 0. Create Prototype Accounts and Export Them

Only do this once. Once you create a user file you like, you can use it over and over, on any different sites and tiers you like.

Step 1. Import Accounts on Destination Sites

You can start with a newly-created repository which needs to have user accounts added. It only has the initial administrator login, e.g. bigbird. Use the import service to add users from the file you created in step 0. The following command adds all of the accounts except bigbird (since it already exists), and aborts without changing anything if there are already duplicates of any of the users on the destination repo. It will print "status=200" on success.

...

Note that the transform=yes argument means import will translate the instance URIs of the new users to newly-created URIs in the repository's default namespace. This is usually what you want. If you are positively restoring users already in the correct namespace and you want to preserve the old URIs, substitute transform=no.

Step 2. Testing Users

The easiest way to test the existence and details of a user is with the /whoami service. It does not show roles, however, you'll have to go to the repository administrative UI for that (or take it on faith). For example, after restoring users including curator, this is how you'd check that curator exists:
