        <p>Attendees at the WWW2007 panel session on Open Data [1, 2] will remember a wide-ranging discussion of the role that easily accessible data could play in endeavors from scholarly publishing [3] to the creation of canonical product catalogs [4]. The authors argued there and subsequently [5] that an effective and flexible licensing framework is needed in moving forward. Paradoxically, we argue that you need to actively and consciously assert your desire that third parties be able to use data you place online in order for those 'visible' and 'accessible' data sets to be utilized most effectively.</p>

      <title>INTRODUCTION</title>
      <p>
        Much attention is currently being paid to the concept of Open
Source [
        <xref ref-type="bibr" rid="ref12">13</xref>
        ], and to the value its adoption can bring to the
development and dissemination of software within a vibrant
mixed economy comprising traditionally commercial, open
source, and hybrid solutions of various forms. In the academic
sector, too, existing models of publication are being challenged by
the rise of the philosophically related Open Access [
        <xref ref-type="bibr" rid="ref13">14</xref>
        ]
movement. Here, as in the software world, the vehement
polarization of early protagonists is increasingly giving way to a
more pragmatic world view in which various models co-exist to
meet a diverse set of requirements.
      </p>
      <p>In scholarly publishing, there has tended to be an unfortunate
presumption that rights in the raw data underpinning a paper’s
analyses and conclusions will be retained and enforced; that these
data will not be shared in order to allow readers to test the results
for themselves. More recently, some funders have begun to
require that both reports of research and data produced by research
be made easily available for re-examination, and organizations
such as Creative Commons are taking a serious interest in this
area with their Science Commons project.</p>
      <p>
        However, beyond these scholarly disciplines far less attention has
been paid to the manner in which data can be used and reused,
with only a few projects such as OpenStreetMap [
        <xref ref-type="bibr" rid="ref14">15</xref>
        ] really
challenging the traditional models of control over creating and
accessing the underlying data upon which so many applications
rely.
      </p>
      <p>Almost everywhere one looks, now, increasing volumes of data
are being published to the Web with the explicit aim of
interoperability and a strong but often implicit commitment to
openness. Despite this commitment in principle, data is rarely
made available in a manner that makes it straightforward to
ascertain the uses to which it may subsequently be put by a third
party. In small, tightly-knit groups where interchange of data may
be governed by existing social norms this may rarely present a
problem. However, with data interchange and interoperability
reaching Web scale, social norms alone cannot be relied upon to
enforce fair and appropriate usage of data. Instead, licenses are
required that make explicit the terms under which data can be
used. By explicitly granting permissions, the grantor reassures
those who may wish to use their data, and takes a conscious step
to increase the pool of Open Data available to the web.
In this paper we will briefly outline and contextualize existing
work in the field, highlighting the cases in which existing licenses
are appropriate and those areas in which they can not be
meaningfully applied. We will then present the work of the Open
Data Commons, and describe the rationale behind the Open Data
Commons Public Domain Dedication and License.</p>

      <title>2. DATA IS NOT A CREATIVE WORK</title>
      <p>Discussion of opening access to resources on the web often turns,
sooner or later, to the laudable activities of Creative Commons,
and we shall look at this effort in a little more detail shortly. It is
important to understand at this point, however, that the legal
protections upon which Creative Commons (and other similar)
licenses rely depend upon national and international legislation
around Copyright. Copyright protection applies to acts of
creativity (‘creative works’), and categorically does not extend
either to databases nor to those non-creative parts of their content.
Despite numerous cases in which well-meaning individuals or
organizations release data onto the Web and apply a Creative
Commons or similar license to this, there is no meaningful - or
defensible - legal basis to this and they have in effect done little
more than sow yet more confusion in this already complex space.
If we are to release large quantities of data onto the Web with the
explicit intention that it be used and reused, then a different
solution is required.</p>

      <title>3. POLARIZING THE OPTIONS</title>
      <p>
        Back in November of 2004 James Boyle published ‘A Natural
Experiment’ in the Financial Times [
        <xref ref-type="bibr" rid="ref15">16</xref>
        ]. This piece saw him
debating the merits of intellectual property rights over data with
Thomas Hazlett and Richard Epstein. His primary thrust was that
we should be making policy decisions in this area based on
empirical data about the economic benefits one way or another.
Something all three protagonists agree on.
      </p>
      <p>Much has changed since 2004, not least our understanding of how
the web can affect the way we collaborate, share, communicate; it
fundamentally affects the way we live. We chat, we blog, we
Twitter, we Flickr and we Joost. Content flows from person to
person in unprecedented ways and at unprecedented speeds. This
changes the nature of the experiment that Boyle talks about.
In Europe we have a right somewhat akin to Copyright,
specifically intended to provide protection for aggregations of
data; databases. If this European Database Right were working,
“we would expect positive answers to three crucial questions.
First, has the European database industry’s rate of growth
increased since 1996, while the US database industry has
languished? [...] Second, are the principal beneficiaries of the
database right in Europe producing databases they would not have
produced otherwise? [...] Third, [...] is the right promoting
innovation and competition rather than stifling it?”
Boyle’s first two questions centre around the creation of databases
and his third, by his own admission, is difficult to measure. If one
of our primary goals for the growth of the Internet is to have a
web of data that can be linked and accessed across the globe we
may be better served by assessing how companies might make
data open rather than closed.</p>
      <p>Boyle asks for, and discusses, the empirical evidence of databases
being created in the EU and US. The differences in numbers
should provide insight into the economic ups and downs as the
EU adopted a robust database right in 1996 while the US ruled
against such protection in 1991.</p>
      <p>Boyle explains that the US Chamber of Commerce oppose the
creation of a database right in the US;
“[The US Chamber of Commerce] believe that database providers
can adequately protect themselves with contracts, technical means
such as passwords, can rely on providing tied services and so on.”
And therein lies the rub. Without appropriate protection of
intellectual property we have only two extreme positions
available: locked down with passwords and other technical
means; or wide open and in the public-domain. Polarising the
possibilities for data into these two extremes forces the creator of
data toward one of two extremes, neither of which are likely to
address the nuance of their own circumstances and desires.
With only technical and contractual mechanisms for protecting
data, creators of databases can only publish them in situations
where the technical barriers can be maintained and contractual
obligations can be enforced.</p>
      <p>We don’t tolerate this with creative works, our photographs, our
blog posts and so on. Why would we expect it to make sense for
databases? Whether or not it makes sense comes down to whether
or not it is beneficial to society. We allow Copyright in order to
provide adequate remuneration to be collected by the creator of a
work. We allow patents to allow the recovery of development
costs for an invention. Which is database right more like?
The patent is a very broad monopoly. If one had a patent on the
clock, a mechanical means of measuring the passage of time,
nobody else would be able to make clocks without payment of
some fee. Copyright on the other hand is much narrower, only
allowing protection for the specific design of particular clocks.
Database right in the EU is like Copyright. It is a monopoly, but
only on that particular aggregation of the data. The underlying
facts are still not protected and there is nothing to stop a second
entrant from collecting them independently.</p>
      <p>Richard Epstein points to this in his contribution to the Financial
Times’ discussion;
“The question is why do databases fall outside [the general
principle of copyright], when the costs of compilation are in many
cases substantial for the initial party and trivial for anyone who
receives judicial blessing to copy the base? In answering this
question, it will not do to say, as the Supreme Court said in the
well known decision in Feist Publications v. Rural Telephone
Service, (1991) that these compilations are not ‘original’ in the
sense that it requires no thought to check the spelling of the
entries and to put them all in alphabetical order. But that obvious
point should be met with an equally obvious rejoinder. If it
requires no thought or intelligence to put the information together,
then why not ask the second entrant into the market to go through
the same drudge work as the first.”
This is exactly what we see happening with Open Street Map. The
United Kingdom’s national mapping agency, Ordnance Survey,
have rights over the map data they have collected. The protection
covers the collection of geospatial data that they have created.
They are not granted a monopoly in geospatial data.</p>
      <p>This leaves a special case of databases, those which are created at
low cost as a by-product of normal business. Examples used in
Boyle’s article are telephone numbers, television schedules and
concert times. Boyle gives us the answer directly;
“the [European] court ruled that the mere running of a business
which generates data does not count as “substantial investment”
enough to trigger the database right.”
That a database right may not and should not apply in all cases,
and that there is a requirement to restrict anti-competitive
practices, does not necessarily extend to the conclusion that a
right is not required.</p>
      <p>It seems that much of the debate around intellectual property
rights has focussed on how they are used to keep things closed.
Having suggested earlier that we have only the abilities to keep
databases locked away or in contrast open them completely, there
is scope for considering - and defining - protections that lie
somewhere between these two extremes.</p>
    </sec>
    <sec id="sec-6">
      <title>4. EXISTING LICENSES</title>
      <p>
        In response to Thomas Hazlett’s contribution to the Financial
Times debate, Boyle asks;
“How many databases are now created and maintained entirely
‘free’ and thus escape commercial directories altogether? There
are obviously many, both in the scientific and the consumer realm.
One can no more omit these from consideration, than one can
omit free software from the software market.”
This is an important point, and worthy of consideration. Taking
one of the most prevalent free software licenses, the Gnu Public
License [
        <xref ref-type="bibr" rid="ref16">17</xref>
        ], what might that look like for data?
One of the primary functions of the GPL is that it enforces
Copyleft – the requirement to license derivative, and even
complimentary, works under the same license. That is, any
commercial software that makes use of GPL code must, under the
terms of the license, also be released under the GPL. The viral
nature of this license is possible only because of the legal backing
of Copyright legislation.
      </p>
      <p>Without a legally recognised Database right, communities have no
mechanism to publish openly and still insist upon this kind of
Share-Alike agreement for their data.</p>
      <p>Consider the impact of this for situations where you you might
use the idea of promiscuous copying to maintain the availability
of data. Promiscuous copying relies on two things; lots of copies
being made and lots of copies being available. Without the
necessary licensing in place there is no mechanism with which to
compel those who have copies to make those available. Public
Domain means, by definition, no restriction. There is nothing to
prevent someone from taking data released into the public domain
and locking it away behind a pay wall or similar restrictive
mechanism.</p>
      <p>Copyleft is just one position along a spectrum where ‘locked
away’ and ‘free as a bird’ sit at each end. What the web shows us
is that other business models form crucial parts of the eco-system.
Epstein picks up on the controlling aspect of Boyle’s argument:
“They can control their list of subscribers; give them each
passwords; charge them based on the amount of the information
that is used, or some other agreed-upon formula; and require them
not to sell or otherwise transfer the information to third parties
without the consent of the data base owner.”
Imagine if this were true of Copyright material on the web? It has
been, and still is on the occasional site. But mostly copyright
owners are starting to see the value of publishing content online
and they are underpinning the delivery of that content to
consumers with other business models. Without Copyright the
types of business that could participate would be reduced.</p>
      <sec id="sec-6-1">
        <title>Epstein goes on to say:</title>
        <p>“The contractual solution is surely preferable, because general
publication will allow for use by others that may not offend the
copyright law, but which will block the possibility of payment for
the costly information that is supplied.”
And again, the very heart of the matter. If we are to encourage
those who have large databases to make them open, to post them
on the Semantic Web, we must provide them with models and
solutions that are preferable to technical barriers and restrictive
contracts. Allowing them to pick their own position on the
spectrum seems a necessary part of that. You can see any form of
protection in two lights. When Boyle says;
“They make inventors disclose their inventions when they might
otherwise have kept them secret.”
we say;
“They allow inventors to disclose their inventions when they
might otherwise have had to keep them secret.”
In the world of creative works, notions espoused by Lawrence
Lessig and others over a number of years are becoming
increasingly well understood. A Creative Commons license, for
example, is recognized as giving the holder of rights an ability to
prospectively grant certain permissions rather than limit use of
their work by expecting all comers to request these permissions,
again and again. Those rights are not cast aside, removing all
opportunities to protect your work, your name, or your potential
revenue stream. Rather, you are provided with a means to
explicitly declare that your work may be used and reused by
others in certain ways without their needing to request permission.
Any other use is not forbidden; those uses must simply be
negotiated in the 'normal' way... a normal way that also applied to
those uses covered by Creative Commons licenses before the
advent of those licenses.</p>
        <p>Creative Commons licenses are an extension of copyright law, as
enshrined in the legal frameworks of various jurisdictions
internationally. As such, it doesn't really work terribly well for a
lot of (scientific, business, whatever) data... but the absence of
anything better has led people to apply Creative Commons
licenses of various types on data that they wish to share. It will be
interesting to see what happens, the first time someone seeks
redress in a court, citing the Creative Commons license that they
selected as an appropriate protection against abuses of their data.</p>

      <title>5. A LICENSE FOR OPEN DATA</title>
      <p>
        Back in 2006, Talis released a first public attempt at an open data
license, the Talis Community License [
        <xref ref-type="bibr" rid="ref16">17</xref>
        ], and began to use it for
some early submissions to the Talis Platform [
        <xref ref-type="bibr" rid="ref17">18</xref>
        ]. In building a
Platform, we understood from the outset the importance of
recognizing - and celebrating - the rights of those contributing
their data to the shared pool. The Talis Community License
allowed us to do that.
      </p>
      <p>
        Not long after, Tim O'Reilly wrote;
“One day soon, tomorrow's Richard Stallman will wake up and
realize that all the software distributed in the world is free and
open source, but that he still has no control to improve or change
the computer tools that he relies on every day. They are services
backed by collective databases too large (and controlled by their
service providers) to be easily modified. Even data portability
initiatives such as those starting today merely scratch the surface,
because taking your own data out of the pool may let you move it
somewhere else, but much of its value depends on its original
context, now lost.” [
        <xref ref-type="bibr" rid="ref18">19</xref>
        ]
At Talis, we have an interest in seeing large bodies of structured
data available for use. Through the Talis Platform, we offer one
means whereby such data may be stored, used, aggregated and
mined, although we clearly recognize that similar data may very
well also be required in diverse contexts.
      </p>
      <p>Recognizing that contributors of such data need to be reassured as
to the uses to which we - and others - may put their hard work, we
spent some time drafting what was then called the Talis
Community License. This draft license is based upon protections
enshrined in European Law, and has been used 'in anger' for a
while to cover contributions of millions of records to one
particular application on the Talis Platform.</p>
      <p>Despite interest in open (or 'linked') data, licenses to provide
protection (and, of course, to explicitly encourage reuse) are few
and far between. Amongst zealous early adopters, there does seem
to be a tendency to either (mis)use a Creative Commons license,
to say nothing whatsoever, or to cast their data into the public
domain. None of these strategies are fit for application to
business-critical data.</p>
      <p>
        Building upon our original work on the TCL, we provided
funding to lawyers Jordan Hatcher and Charlotte Waelde [
        <xref ref-type="bibr" rid="ref9">10</xref>
        ].
They were tasked with validating the principles behind the
original license, developing an effective expression of those
principles that could be applied beyond the database-aware shores
of Europe, and working with us to identify a suitable home in
which this new license could be hosted, nurtured, and carried
forward for the benefit of stakeholders far outside Talis.
The result of this effort was the Open Data Commons Public
Domain Dedication and License [
        <xref ref-type="bibr" rid="ref10">11</xref>
        ], itself a fusion of ideas from
the Talis Community License, an initial phase of redrafting from
Hatcher and Waelde, and a focussed piece of activity to align with
a related framework developed within the Science Commons
project of Creative Commons at the same time.
      </p>
      <p>
        The current iteration of the license asks licensors to waive various
local protections in order to create a level playing field upon
which a set of ‘community norms’ may be documented in order to
define a set of shared expectations as to the ways in which the
data may subsequently be reused. The first of those community
norms is defined on the Open Data Commons site [
        <xref ref-type="bibr" rid="ref11">12</xref>
        ], and all
concerned expect compatible sets of norms to be created
elsewhere in time.
      </p>
      <p>
        The Public Domain Dedication and License is now available for
use, following a period of consultation. At the time of writing, all
those concerned in getting to this stage are engaged in the process
of placing the wider Open Data Commons initiative itself on a
sound footing, creating a safe place in which this license and
those to follow it may be maintained and evolved. The Open
Knowledge Foundation (OKF) in Cambridge, UK, is to lead by
providing that neutral new home, and funders, drafters and other
interested parties are united in supporting this move to a sound
and sustainable footing [
        <xref ref-type="bibr" rid="ref19">20</xref>
        ].
      </p>
    </sec>
    <sec id="sec-8">
      <title>6. CONCLUSIONS AND OUTLOOK</title>
      <p>There is a lot still to do, but the interdisciplinary collaboration
we’re already seeing with respect to permissive licensing of data
for the web means that we can all begin to move forward in
lowering the walls of our silos, releasing data to play its part in
the Data Web. All of us invest heavily in collecting and curating
data, which is traditionally locked away and left to atrophy, failing
to achieve anything like its true potential. Appropriately released
and sensibly licensed, data held by every one of us can contribute
hugely to the promise of the Semantic Web. Here, the whole
really is far greater than the sum of its parts.</p>
      <p>
        The current license is available for use. It provides us with the
capability to build upon the efforts of those philanthropic
contributors to the existing Linking Open Data project [
        <xref ref-type="bibr" rid="ref20">21</xref>
        ], and
to take the linked data proposition to that broader market of data
curators who need more persuasion and reassurance. The
opportunity is immense, as is the benefit to the Semantic Web
itself.
