ckan lodcloud: "use one of" topic tag?

Richard and Anja,

http://www4.wiwiss.fu-berlin.de/lodcloud/ckan/validator/validate.php

reports:

Missing topic. No topic tag found. Use one of: media, government,
geographic, publications, crossdomain, lifesciences,
usergeneratedcontent, ecommerce, schemata.

( [1] also says "one of" )

Does this mean that a lodcloud dataset should have one _and_only_one_
topic tag? Or are more acceptable?
How do you decide the "primary" tag if multiple are given?

Thanks,
Tim Lebo
