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 

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?
