Tiago Santos license statement doubt

[Tiago Santos]

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 also be licensed under  have also MPLv2/LGPLv3+ dual license.

The main doubts come from the second patch and third patches posted on bug 101616 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 may be useful to others.
Best regards,

Tiago Santos
