Hi Christoph & All,
1. As mentioned, I am happy with CC0 too.
2. Since "CC BY 4.0" had made improvement to cover "data" more
adequately (which were lacking in "CC BY 3.0" or previous
versions). I believe "reservations" from the data community to use
"CC BY" only applies to "CC BY 3.0" or previous versions.
 The main improvements of CC 4.0 compared with CC 3.0. CC 4.0 is
that it now covers database rights, also known as sui generis database
rights ... ref.
3. I prefer "CC BY 4.0" - the "BY" in particular - because it still
provides "Attribution" while allowing people to do whatever they need
to do with the data (the license is a "gift" license, and "not
4. I prefer "CC BY 4.0" - the "CC" in particular - because it has been
around for quite a while, properly maintained. It has a great track
record and was created/supported by some of the folks (like Larry
Lessig and John Wilbanks) whom I have a lot of respect for. see also:
5. Besides the above reason, see also:
6. While "attribution stacking" may need some (but probably not a
huge) effort to maintain, I think it is only fair to those (like
OntoIOp WG members) who have spent an inordinate amount of time and
energy into creating those data and content, to be properly
Again, I defer to the majority preference of the team and the community.

Dear Christoph and All,
Thank you very much for the input and the well thought through recommendations.
In particular, re. choice of license ...
> [CL] 1. License of the dataset: A linked open dataset should have a license, which you usually choose from a small set of well-known licenses depending on your requirements. After some initial research I found the following ones appropriate. ... I believe that a share-alike license is too restrictive, so ...
[ppy] +1 on your disposition ... thank you for doing the research; I
applaud your recommendation.
> [CL] ... so two reasonable ones remain ... [ ODC 1.0 or CC0]
[ppy] besides those two, one might also consider "CC BY 4.0" - see:
Depending on the preference of the majority of the OntoIOp
WG/community, I would be happy with anyone of these three choices -
ODC-1.0, CC0 OR CC-BY-4.0 ... personally, if we are taking a poll,
then I would vote for CC-BY-4.0.
Thanks and regards. =ppy
