Bot or not, it is a widely held view that (tabular) data extracted
from Wikipedia is in the public domain. At least that's what I
believe. I'm sorry that I have no sources to cite.
You might want to look at other projects that reuse data extracted
from Wikipedia dumps, such as
dbpedia.org.
Traditional copyright doesn't apply to extracted data, so the GFDL
is not applicable. In various countries, "catalog rights" or
"database rights" might be applicable to such data, but that right
then belongs to those who compiled the table of data (catalog,
database), not to the original authors of articles*. I strongly
doubt that you could claim such rights if you just extracted
interwiki links from the XML dumps published by the Wikimedia
Foundation.
*Similar examples are Bible concordances or scientific cross
indexes, for which catalog rights belong to the indexers, rather
than to the original authors of the texts.
I am not a lawyer. You might get better answers from Mike Godwin,
who can speak for the Wikimedia Foundation.
