Tiago Santos license statement doubt

Good evening,

I am here after submitting a few patches in Bugzilla.
Recently, I have been pointed to the Get Involved page, and I would like 
to subscribe to the license terms posted there, though I would like to 
ask advice about my previous submissions before proceeding.

The first patch is a corrected merge of European Portuguese and 
Brazilian LibreOffice auto-correction files, explained and submitted on 
bug 97439.
I do not have many doubts about this patch since it was based on two 
files already present in LibreOffice, and as such, they should also be 
licensed under MPLv2/LGPLv3+ dual license.

The main doubts come from the second patch and third patches, posted on 
bug 101616. They are vastly increased thesaurus for European Portuguese 
language (though the third patch may be suitable for Brazilian 
Portuguese after review).
These last two patches were posted as a package with a copy of the base 
licenses since they are based in the already existing thesaurus from 
LibreOffice (MPLv2/LGPLv3+ dual license) and two other European 
Portuguese academic ontologies with free distribution licenses. I 
requested email approval from of the author, in addition to the public 
claim of free use from project PAPEL, and Creative Commons Attribution 
3.0 Unported license from project Onto.pt. Though they should be 
compatible with MPLv2/LGPLv3+ dual license, I am not absolutely sure 
they are.

Can someone with more knowledgeable of this licensing terms advise me on 
this matter, so I can proceed with the subscription to the licence, and 
these former patches can be made useful to others.


Best regards,

Tiago Santos
