For a long time now (since 2006 or earlier) Koha has been able to support RDA through its frameworks mechanism. But as it was a moving target no one had documented how before. Now it’s kinda settled,maybe, at least this week it is. I thought it would be a good time to write up how to add support.
And its really really simple, you go to the Koha wiki, to the frameworks page, download the RDA framework, then load it into Koha. So you want RDA support in Koha, the question you must ask yourself is : ‘Do I have 5 minutes to spare?’ (also can I afford to pay the exhorbitant amount JSC charges for the standard http://www.rdatoolkit.org/pricing). If the answer is yes, then you can have RDA support.
Here’s a record in Koha that I got from Library of Congress
The question of what do you do with these RDA compliant records now you have them is an exercise I leave up to the reader.
