  1. Greetings, Rufus.

    I am maintainer of russian project OpenGovData.ru (http://www.opengovdata.ru) and I think it’s possible to convert collected data to the CKAN catalog.

    So what do you think about russian CKAN catalog?

    Best regards,
    Ivan begtin

  2. @Ivan: it would be very easy to convert to the CKAN catalog and we’d delighted to help you do this. First, thing to do is to make a Russian translation, this shouldn’t take more than an hour or two:


    You can then deploy a CKAN instance (or we can do one for you …).
