Pascal, I somewhat disagree with that statement: there is (and should
be) a clear (boolean) definition what open means: http://opendefinition.org/

The Open Definition precisely defines the requirements for a license in
order to be called open. Allowing remixing and republishing,
availability of data in bulk and non-discriminatory licensing allowing
commercial reuse are core requirements of the open definition.

Open Data is not cardinally different from other "open" domains, e.g.
open source software and for open source software there exists also a
clear definition (overseen by OSI), which is meanwhile widely enforced.

I'm a big fan of both -- Linked Data as a data integration paradigm
within and between organizations AND Linked Open Data as a way to share
data and knowledge openly on the Web. With the Open Definition we have a
clear way to distinguish between the two.



PS: A few days I attended a talk by a German lawyer about data licensing
and he said that if you publish your data on the Web without access
control, it is (at least in Germany) not secured by any IPR and everyone
can (without asking the publisher) use the data, republish it and do
whatever with it as he pleases. If this is really true, at least for all
Germans all data published as Linked Data on the Web without any license
would be Open Data too ;-)
