Oh! I didn't know... but if you can insert a "SQL" expression then R2RML
is certainly imperative.
Now I am very curious about the "Prolog" question, too, and I would like
to hear more opinions.
To foster the discussion, I have posted about "RDF Mappings and
Licenses" here: http://licensius.com/blog/MappingsAndLicenses

Interesting distinction, but I'm not sure I buy it.
Does that mean software licenses don't apply to PROLOG code?
I can actually make R2RML mappings more imperative than PROLOG cuts by
using control flow features of SQL.

Dear Roberto, all
Well, I have not heard about any case in a trial court about this and
the legal texts seem somewhat ambiguous. Also, I have not heard other
qualified opinions on this particular regard. So, this can be matter
for a friendly discussion.
But I still lean towards *not* considering a mapping (for example the
R2RML below) as a computer program.
The mapping is /declarative/, not /imperative/. They are not
/instructions/, as required in the legal text.
*Think of HTML pages*. I dont think they are regarded as software.
People don't license them with a BSD license. They use
CreativeCommons licenses, intended for general works. You /declare /a
table, a computer program will process it. (Yet, a Javascript piece
would be made up of /instructions/).
I hope I clarified my point.

Dear Víctor, Tom, all,
Maybe I've missed something but if what is going to be licensed are
R2RML mappings, for me this is code.
As Víctor quoted, acomputer program is (WIPO): "a set of
instructions, which controls the operations of a computer in order
to enable it to perform a specific task".
This is just what happens with R2RML mappings, they are based on a
metalanguage that is read by a computer using a R2RML interpreter
(implemented using another programming language but just similar to
a compiler) that at last executes a set of instructions that read
data from a source and generate a data stream in the output...
My 2c,
Roberto

Well, ODC data licenses include *both* copyrights and database
rights.
So you dont give up your claims for having made a creative work...

Just seen this thread, apols for the slow response Barry...
Of course IANAL and all that, but I disagree with Victor's conclusion.
I would argue that the individual mappings are creative works (as you
say), and therefore a CC license would apply (better still, why not
apply a public domain waiver so they're totally open?).
The collection as a whole would probably qualify as a database, at
which point Victor's points about a DB license would be relevant.
As others have mentioned, the data created by the execution of these
mappings is another issue altogether, which you seem to have covered.
My 2p worth -- hope it helps :)
Tom.

Barry,
My opinion is the following:
1. Code license NO. A computer program is (WIPO): "a set of instructions,
which controls the operations of a computer in order to enable it to perform
a specific task"
2. Intellectual Property. I'd say no in this case. Some databases are
protected by IP law. They are if they can assumed to be "collections of
literary or artistic works such as encyclopaedias and anthologies which, by
reason of the selection and arrangement of their contents, constitute
intellectual creations, are to be protected as such, without prejudice to
the copyright in each of the works forming part of such collections".
So, if you have made your mapping automatically, they are NOT under the
umbrella of IP laws.
3. Database law. YES (where it applies). Relaxing the requirements, a sui
generis rights is defined in Europe to protect your database if you have
made an investment (in time or money) when making the database. Rights
(extraction and reutilization) are kept for 15 years and are not recognized
in USA and many other countries.
--> Conclusion. Instead of using CreativeCommon licenses (excepting CC0
which is ok), use Data Licenses (for example ODC), which include in their
text a reference to the European database law.
Regards,
Víctor

Incidentally, to clarify, I meant to ask a more fundamental question about
mappings: are these creative works, deserving themselves of a CC license, or
executable code, deserving of a code license?
Whichever way, I'd like to make them as encumbered as possible.

I'd like to publicly release R2RML mappings for the MusicBrainz dataset.
DBpedia has shown interest in including the subset that can be used to
create a linkset.
Any idea what (kind of) licence could/should apply? (To be clear, to the
mappings, as opposed to the dataset)
I'd also like to attach, since R2RML is RDF, a licence and attribution on a
per rr:TriplesMap basis. (The mappings are hosted on github and
contributions will be accepted as I'm never going to get through all of the
MB Advanced Relationships, a moving target, myself and I'm being a
bottleneck.)
The question's also been raised on whether a given licence can in turn
impose conditions on the triples that are created using it (as derivative
works)? Does that sound feasible?
Any input appreciated.
