If needing to populate X-Registry with a large number of entries, it would be very tedious and time-consuming to do this all manually… so what facilities, tools or scripts are available to aid bulk data loading? For example, to take data out of a spreadsheet or a database and upload from here to X-Registry via its own API?

As part of the install the product-config script has several data migration options, bulk extract being but one.

Misread your posting.

I am also interested in bulk loading of X-Registry meta-data (organizations, users, policies, taxonomies, etc) and X-Registry data (services) from one instance of X-Registry 6.6 to another.
