Wikipedia relicensed: consequences for DBpedia and downstream?

http://meta.wikimedia.org/wiki/Licensing_update/Implementation
[[
As per the licensing update vote result and subsequent Wikimedia 
Foundation Board resolution, any content on Wikimedia Foundation 
projects currently available under GFDL 1.2 with the possibility of 
upgrading to a later version will be made available additionally under 
Creative Commons Attribution/Share-Alike 3.0 Unported.

Specifically with regard to text, after this update, only dual-licensed 
content or CC-BY-SA-compatible content can be added to the projects, and 
GFDL-only submissions will no longer be accepted. In other words, 
CC-BY-SA will be the primary Wikimedia license for text, and GFDL will 
be retained as a secondary license.
]]

According to http://wiki.dbpedia.org/Datasets#h18-18 DBpedia is 
available under 
http://en.wikipedia.org/wiki/Wikipedia:Text_of_the_GNU_Free_Documentation_License

Will it also be made available under 
http://creativecommons.org/licenses/by-sa/3.0/ ? ("Attribution-Share 
Alike 3.0 Unported")

What do these distinctions mean in practice when we're dealing with 
mergable data rather than documents?

"Share Alike — If you alter, transform, or build upon this work, you may 
distribute the resulting work only under the same, similar or a 
compatible license."

... seems rather strong (eg. for intranet triplestore use).

Is anyone here not not a lawyer?

cheers,

Dan
