a data licensing problem

I have a problem that I would like y'all to consider.  A company sells
datasets.  They wish to cooperate with the opensource folks to the

This sounds like Open Motif, where it's whether or not your kernel is
Open Source that determines whether or not you can get a libre license
for Motif.  We decided that that scheme was not OSD-compliant, and indeed
it never claimed to be.

A dataset is entitled to a copyright, albeit a thin one.  The individual
facts contained in it are possibly not copyrightable.  But the dataset
itself may be licensed on whatever terms the copyright owner wants, as a
copyrightable compilation, including under multiple licenses.  (You
omitted to tell us what the dataset contains.  The telephone book is
copyrightable, although the individual names and numbers aren't.)  

Suppose the copyright owner wants to let everyone use the dataset, but
any modifications that are made and distributed are to become available
under reciprocal terms (e.g., under the same license).  The OSL will
suffice.  I believe that a modified dataset is a derivative work of the
original dataset, but it might be best for your hypothetical company to
hire a lawyer to check out the cases on that point in his jurisdiction.
The issue is, if you merely add more non-copyrightable facts to a
dataset, is that considered a modification/derivative work?  By analogy,
if I were to take a published dictionary and add definitions and
republish it, am I creating a derivative work of the dictionary?  I
think so, but I'd want to verify this point.

The copyright owner can separately license the dataset to anyone he
pleases under any license he wants.  He can allow incorporation into
proprietary products without a reciprocity provision, for example, in
exchange for money.  He can promise follow-on versions (e.g.,
"maintenance" or "support") for a fee.  I've seen client companies make
good money selling compilations of facts gleaned from the public trade
press; their customers simply wanted to pay for the service of creating
and publishing the collection and keeping it current.  In another
example, companies can also make money selling collections of
freely-available clip art.  

To be sure that the dataset remains available under the open source
definition, your hypothetical company should license it under a license
that is OSI approved and that doesn't treat "software" as a narrow
category of intellectual property.  That's why I'd recommend the OSL or
the AFL.  The AFL, of course, doesn't include the reciprocity provision,
so it probably isn't what your hypothetical company would want.

The Sleepycat license is vendor and product specific.  It refers to "DB
software" (whatever that is) and includes the following warranty: "THIS
SOFTWARE IS PROVIDED BY SLEEPYCAT SOFTWARE ``AS IS'' AND"  The
Sleepycat licenses is not reusable as is by other vendors.

I notice that the Sleepycat license as published on the OSI website

Yes, but a work that uses the Sleepycat libraries is clearly a derivative
work of Sleepycat, at least if it does static linking.  Saying that there
exists *data* that only open-source applications can access is like trying
to insist (by legal, not technical, means) that your page on the WWW is

But that isn't what they want.  They want only certain privileged persons
to use the dataset: those who run free operating systems, or those who
run free applications, it's not clear which.  (What about free applications
on unfree OSes, or vice versa?)  That way they can continue to sell the data

Sure you are.  The definientia in the dictionary are not subject to
copyright, but the definitions themselves certainly are -- compare any
two dictionaries from different companies to see how very different the
definitions are: no content-form merger here!  The exemplary quotations
are generally considered fair use, although I don't know of any actual
court cases about this.

The Feist court was more ambiguous than either your comment or my
comment would indicate.  A telephone book that contains simply an
alphabetical listing of names, addresses and telephone numbers of every
telephone subscriber is probably not copyrightable.  The yellow pages,
on the other hand, probably is.  A telephone directory that contains
other copyrightable subject matter (How To Use a Telephone"
instructions, for example), or marital status, religion, etc., might be
copyrightable.  Neither of us knows what Russ' hypothetical company is
actually putting in its dataset, which again points out the folly of
giving legal advice over the Internet in response to a hypothetical
question.

You're right.  I twisted Russ' hypothetical to get a result I wanted.

2002-11-08 Thread Lawrence E. Rosen
In rereading the Feist case I found the following quotation from a
similar case.  I thought you might find it interesting.

Rockford Map Publishers, Inc. v. Directory Service Co., 768 F.2d 145
(76h Cir. 1985), cert. denied, 474 U.S. 1061.  [Defendant challenged
copyright protection for plaintiff's map, which was drawn principally
from numerical information in public land-title record books; the
defense was that plaintiff expended little time and effort in compiling
the map that defendant copied.]  The court wrote:

"The copyright laws protect the work, not the amount of effort expended.
A person who produces a short new work or makes a small improvement in a
few hours gets a copyright for that contribution fully as effective as
that on a novel written as a life's work  Copyright covers, after
all, only the incremental contribution and not the underlying
information.

"The input of time is irrelevant.  A photograph may be copyrighted,
although it is the work of an instant and its significance may be
accidental  In 14 hours Mozart could write a piano concerto, J.S.
Bach a cantata, or Dickens a week's installment of Bleak House.  The
Laffer Curve, an economic graph prominent in political debates, appeared
on the back of a napkin after dinner, the work of a minute.  All of
these are copyrightable. /1/

"Dickens did not need to complete Bleak House before receiving a
copyright; every chapter -- indeed every sentence -- could be protected
standing alone.  Rockford Maps updates and republishes maps on more than
150 counties every year.  If it put out one large book with every map,
even Directory Service would concede that the book was based on a great
deal of "industry."  Rockford Map, like Dickens, loses none of its
rights by publishing copyrightable matter in smaller units."
_
/1/ "In principle, Mozart's work is in the public domain and anyway was
a work for hire.  The Archbishop of Salzburg probably held the rights.
There were no copyright laws in seventeenth-century Germany, and Bach
had no way to protect his rights.  Dickens was at the mercy of his
publishers.  Only Laffer's napkin, and not the idea represented by the
graph, may be copyrighted.  But the principle's the thing."

Easterbrook).

The dataset in question (yes, I'm being cagey) is definitely
copyrightable.  And yes, they can copyright it any way they want.
What they want, though, is a way to price differentiate.  They'd like
to be able to specify, for example, that the data could only be
distribute in conjunction with software which is OSD-licensed.  I
think that runs afoul of the OSD term that prohibits discrimination.

They'd *really* like to get the best of both worlds: cooperate with
people who share and stick it to the people who don't (or, um, can't.)

Aha!  Bing!  That's how you do it!  You publish the data in a special 
open source format, which is unusable by Windows applications.  Sure,
somebody in the open source world might create a format converter, but 
why would they bother?  Even if they did, you're selling the "real"

I  didn't suggest simply copying and pasting it. Simply put the sleepy 
cat license does allow the licensing behavior required.  I doubt very 
much that the said company is using the IP of Harvard and Berkley. Those 
sections could be safely snipped. You actually cannot simply cut and 
past verbatim for various licenses. The real protection lies as Lawrence 
pointed out in the copyright inherent in the data. This company might be 
seeking to allow commercial development of their IP while at the same 
time allowing open source use of the data. Generally and this only 
applies to software it's not uncommon to license differently to closed 
source applications (presumably they are not going to release source 
back to the community or the copyright holder). Does the Academic Free 
license achieve this goal?

As an employee of Reuters, which has been selling price-discriminated
information for over 150 years, there is no way for your company
to do what it wants except to protect its information with the full
force of copyright, and to be really effective, they need exclusive
(or effectively exclusive) control of the source as well, either by
owning it or by being first-to-market all the time.

Otherwise, the people who get to use the information free can undersell
you not with the information itself but with the products of its use.

If they wanted to run that free software crap, they'd do it.
"Obviously", what you get by paying for it is better than the stuff
you get for free.  It's not that Windows users or developers are
stupid.  It's just that they don't mind showing their appreciation by
paying money.  In the open source world, we pay respect.  And that's

And which am I?  I'm typing now on a Windows system that's ssh-ed to
a Linux system running elm.  Does it matter if I use the proprietary
or the Cygwin ssh client?  Exactly how do I get to use your client's
data, if at all?  If I want to count the number of data elements, is
it critical which version of Perl I use?  Or do I have to keep the

Re: a data licensing problem

2002-11-09 Thread Nathan Kelley
To OSI License Discussion,


From: Russell Nelson <[EMAIL PROTECTED]>,

From: Lawrence E. Rosen <[EMAIL PROTECTED]>,

From: Russell Nelson <[EMAIL PROTECTED]>,



I have a problem that I would like y'all to consider.  A company 
sells datasets. They wish to cooperate with the opensource folks to 
the extent that opensource folks can use a free copy of their 
dataset. They would also like to be able to sell that same dataset 
to people using proprietary operating systems.  On the other hand, 
they would also like to comply with the Open Source Definition.

A dataset is entitled to a copyright, albeit a thin one.  The 
individual facts contained in it are possibly not copyrightable.  But 
the dataset itself may be licensed on whatever terms the copyright 
owner wants, as a copyrightable compilation, including under multiple 
licenses.  (You omitted to tell us what the dataset contains.  The 
telephone book is copyrightable, although the individual names and 
numbers aren't.)

The dataset in question (yes, I'm being cagey) is definitely 
copyrightable.  And yes, they can copyright it any way they want. What 
they want, though, is a way to price differentiate.  They'd like to be 
able to specify, for example, that the data could only be distribute 
in conjunction with software which is OSD-licensed.  I think that runs 
afoul of the OSD term that prohibits discrimination.

They'd *really* like to get the best of both worlds: cooperate with 
people who share and stick it to the people who don't (or, um, can't.)

Let me see if I have this correct:

Our hypothetical company is distributing data which, given the right 
software, can be turned into information. They want to apply Open 
Source principles, which are intended for software rather than data, to 
the distribution of their data on open platforms. However, on closed 
platforms they want individuals to pay to obtain the data, and for the 
purposes of this argument, I'll assume that said individuals on closed 
platforms do not have free redistribution.

Since the copyright question has already been answered, I'll skip that 
part.

If the datasets are indeed different depending upon whether you pay or 
not, then the company will be effectively offering two different 
products under two different licenses; one OSD-complaint (presumably, 
as that is the stated goal), and one proprietary. If the datasets are 
the same, then the company can dual-license the same data, again using 
one OSD-compliant license and one proprietary license. These practices 
are nothing new in the software world; what Apple's doing is a prime 
example.

The next question comes to proprietary and/or open changes that come 
back to the company in question, that they want to put into both 
datasets. This is easily solved by requiring the copyrights on changes 
assigned to said company, with those that don't want to do this for 
whatever reason being able to offer additional data as a third-party 
product. How easy this additional data is then able to be incorporated 
back into the main dataset depends upon the technologies in use. Again, 
these practices are nothing new.

The proprietary license involved will, of course, violate the OSD in 
various ways, however I believe that falls outside our purview.

I'm glad to see more interest is being taken in Open Source, however I 
believe that this discussion is off-topic for this list (at least it is 
according to the list info on the site).

Cheers, Nathan.
