Over the past week or so there has been a flurry of posts about ’strong’ and ‘weak’ open access, including the following:
- Strong and weak OA, Peter Suber
- What’s in a Name? Strong and Weak Open Access, Glyn Moody
- The Two Forms of OA Have Been Defined: They Now Need Value-Neutral Names, Stevan Harnad
- Lower Bound Needed for Permission-Barrier-Free Open Access, Stevan Harnad
- Peter Suber on what is strongOA, Peter Murray-Rust
- Further discussion on strongOA and weakOA, Peter Murray-Rust
- How many forms of OA are there now?, Peter Murray-Rust
- Peter Suber’s comments on strongOA/weakOA, Peter Murray-Rust
- Suber-Harnad strongOA/weakOA borderline, Peter Murray-Rust
- More clarification from Stevan Harnad, Peter Murray-Rust
Peter Suber and Stevan Harnad both agree:
The term “open access” is now widely used in at least two senses. For some, “OA” literature is digital, online, and free of charge. It removes price barriers but not permission barriers. For others, “OA” literature is digital, online, free of charge, and free of unnecessary copyright and licensing restrictions. It removes both price barriers and permission barriers. It allows reuse rights which exceed fair use.
There are two good reasons why our central term became ambiguous. Most of our success stories deliver OA in the first sense, while the major public statements from Budapest, Bethesda, and Berlin (together, the BBB definition of OA) describe OA in the second sense.
As you know, Stevan Harnad and I have differed about which sense of the term to prefer –he favoring the first and I the second. What you may not know is that he and I agree on nearly all questions of substance and strategy, and that these differences were mostly about the label. While it may seem that we were at an impasse about the label, we have in fact agreed on a solution which may please everyone. At least it pleases us.
We have agreed to use the term “weak OA” for the removal of price barriers alone and “strong OA” for the removal of both price and permission barriers. To me, the new terms are a distinct improvement upon the previous state of ambiguity because they label one of those species weak and the other strong. To Stevan, the new terms are an improvement because they make clear that weak OA is still a kind of OA.
On this new terminology, the BBB definition describes one kind of strong OA. A typical funder or university mandate provides weak OA. Many OA journals provide strong OA, but many others provide weak OA.
Furthermore, Peter Suber adds:
As soon as we move beyond the removal of price barriers to the removal of permission barriers, we enter the range of strong OA. Hence, an article with a CC-NC license is strong OA because it allows some copying and redistribution beyond fair use (even if it doesn’t allow all copying and redistribution). My own preference is still for the CC-BY license, but we shouldn’t speak as if CC-NC were not strong OA or as if there were just one kind of strong OA.
According to this schema, a cost free publication counts as weak open access, and a publication licensed under a CC-NC license counts as strong open access. Stevan Harnad agrees with the distinction but suggests the need for ‘value-neutral’ terms to describe it - suggesting ‘basic’ and ‘full’.
Its worth adding to this discussion that there is also Open Definition compliant open access, which I understand is equivalent to BBB open access and which is more permissive than ’strong’ or ‘full’ open access. As we blogged a couple of weeks back - anything with the SPARC Europe Seal will be open access in this sense.
As Peter Murray-Rust comments:
Open Source has the OSI which determines whether ot not a given licence is OS. Open Knowledge after only a short time of volunteers has the OKF and has an agreed definition and a list of conformant licences.
Scholarly publications, as literary works, constitute knowledge and hence are covered by the OKD. A journal, monograph or any other publication can still be ‘open as in the OKD’ as with other forms of knowledge. Debates about open access aside, demarcating between knowledge that is ‘open’ and ‘closed’ is precisely what the OKD is there for!
It will be interesting to see what emerges as the new classificatory scheme for open access, and where OKD compliant publications sit on the spectrum. Perhaps these will be called ‘OKD/BBB compliant open access’ journals, or suchlike.

SPARC Europe Seal for Open Access Journals
April 25th, 2008
SPARC Europe (Scholarly Publishing and Academic Resources Coalition) and the Directory of Open Access Journals (DOAJ) have just announced a new SPARC Europe Seal for Open Access Journals.
In order for journals to be approved, they must use a Creative Commons Attribution license - which is compliant with the Open Knowledge Definition. It is great to see growing support for making scholarly publications fully open!
The announcement - which includes comments from OKF advisory board members John Wilbanks and Peter Suber - is reproduced below.
Growing numbers of peer-reviewed research journals are opening-up their content online, removing access barriers and allowing all interested readers the opportunity of reading the papers online, with over 3300 such journals listed in the DOAJ, hosted by Lund University Libraries in Sweden.
However, the maximum benefit from this wonderful resource is not being realised as confusion surrounds the use and reuse of material published in such journals. Increasingly, researchers wish to mine large segments of the literature to discover new, unimagined connections and relationships. Librarians wish to host material locally for preservation purposes. Greater clarity will bring benefits to authors, users, and journals.
In order for open access journals to be even more useful and thus receive more exposure and provide more value to the research community it is very important that open access journals offer standardized, easily retrievable information about what kinds of reuse are allowed. Therefore, we are advising that all journals provide clear and unambiguous statements regarding the copyright statement of the papers they publish. To qualify for the SPARC Europe Seal a journal must use the Creative Commons By (CC-BY) license which is the most user-friendly license and corresponds to the ethos of the Budapest Open Access Initiative.
The second strand of the Seal is that journals should provide metadata for all their articles to the DOAJ, who will then make the metadata OAI-compliant. This will increase the visibility of the papers and allow OAI-harvesters to include details of the journal articles in their services.
‘We want to build on the great work already done by the publishers of many open access journals and improve the standards of open access titles,’ said David Prosser, Director of SPARC Europe. ‘Working with the DOAJ means that we can provide help and guidance to journals who wish to move beyond the first step of free access to full open access and our long-term aim is to ensure that all journals listed in the DOAJ can attain the standards expressed within the Seal’
‘Improving the standards of the rapidly increasing numbers of open access and contributing to the widest possible visibility, dissemination and readership of the journals is very much in line with our mission,’ said Lars Björnshauge, Director of Libraries at Lund University. ‘We are very happy to see the enormous usage of the DOAJ and the support from our membership’
‘Legal certainty is essential to the emergence of an internet that supports research. The proliferation of license terms forces researchers to act like lawyers, and slows innovative educational and scientific uses of the scholarly canon’ said John Wilbanks, Executive Director of Science Commons. ‘Using a seal to reward the journals who choose to adopt policies that ensure users’ rights to innovate is a great idea. It builds on a culture of trust rather than a culture of control, and it will make it easy to find the open access journals with the best policies.’
‘This is an excellent program with two important recommendations. CC-BY licenses make OA journals more useful, and interoperable metadata make them more discoverable. The recommendations are easy to adopt and will accelerate research, facilitate preservation, and make OA journal policies more open and more predictable for users. I hope all OA journals will adopt them –not to get the Seal from SPARC Europe and the DOAJ, but for the same reasons that moved these organizations to launch the program: to make OA journals more visible and useful than they already are,` said Peter Suber, Open Access Advocate & Author of Open Access News.
Open Scholarly Communities on the Web
April 24th, 2008
Dr. Paolo D’Iorio recently invited me to attend the first meeting of an EU funded Working Group “devoted to analyzing the current debate on the legal, economic and social conditions for setting-up open scholarly communities on the web”. The meeting was part of COST:
COST – European Cooperation in the field of Scientific and Technical Research – is one of the longest-running European instruments supporting cooperation among scientists and researchers across Europe. COST is also the first and widest European intergovernmental network for coordination of nationally funded research activities.
Action 32, of which Dr. D’Iorio is Chair, is called “Open Scholarly Communities on the Web” and has two aims:
- to create a digital infrastructure for collaborative humanities research on the Web; and
- to establish and foster the growth of Scholarly Communities that will provide feedback to the IT developers regarding the needs and expectations of humanities researchers and will serve as a core group of early adopters.
Talks included:
- Paolo D’Iorio (CNRS-ITEM, Paris), How to build a Scholarly Community on the Web
- Maria Chiara Pievatolo (University of Pisa), Copyright in Europe. History and perspectives
- Thomas Margoni (University of Trento), How to access primary sources in Europe. The legal framework
- Annaïg Mahé (URFIST, Paris), The market for SSH Journals in Europe
- Jennie Grimshaw (British Library), Negotiating spaghetti junction: legal constraints on archiving government e-documents in the UK
- Christine Madsen (OII, Oxford), The significance of “marketing” digital collections: the case of Harvard
- Yann Moulier Boutang (Professeur de sciences Economiques - Université de Technologie de Compiègne, Directeur adjoint de Laboratoire de l’Unité de Recherche EA 22 23), Economic model(s) of Scholarly Communities: Open Source or Creative commons?
- Francesca Di Donato (University of Pisa), The evaluation of science. From peer review to open peer review
- Eric Meyer and Ralph Schroeder (OII, Oxford), Open Access and Online Visibility in the Age of e-Research
Notes and comments
- For many humanities subjects, having something like the public domain calculators would help to facilitate the growth of open resources for scholarly communities built on works in which the copyright has expired.
- Paolo’s presentation of Nietzsche Source and the Discovery project gave a compelling vision of how communities might grow around a resource for corpus based scholarship - with users having their own virtual workspace with annotations and notes that could be shared with other users. The ‘Scholarsource’ system would have stable URLs to support accurate citation, and robust ontologies to facilitate exploration of the material. Licensing that permits re-distribution is also a good preservation strategy.
- The term ‘open’ was often not used in the sense of the Open Knowledge Definition. Several projects used licenses with non-commercial restrictions. While some participants assumed that scholars and institutions would often prefer that their work was not exploited commercially - it would be great if public domain sources such as documents, images and records, could be published under an open license. An approach which recommended open licensing for material that had not been enhanced (scans, text files …) could help to stimulate the growth of a commons that would encourage greater experimentation and collaboration than one which restricted certain kinds of re-use (cf. 7. and 8. in the OKD).
- The importance of a close working relationship between scholarly communities and technologists. It is crucial that technical development is informed by the needs and working practices of researchers. This is something we’ve been thinking about in relation to Open Shakespeare and Open Milton. Open licensing allows developers to experiment with scholarly material to develop new tools and applications that could be of unanticipated value (e.g. semantic approaches, text analysis or visualisation).
- Legal, technological and social obstacles to building open scholarly communities. We have various legal mechanisms and emerging technologies to facilitate such communities. Sometime the most hard parts are social - in growing user base, increasing participation and so on. Value and limits of ‘build it and they will come’ approach.
Open Visualisation Workshop in London
April 17th, 2008
We are currently in the process of organising an informal, hands-on workshop for those who work with, or are interested in, open-source visualisation technologies:
The event will take place somewhere in central London on a weekend in May. If you are interested in participating, please add your name to the wiki page and specify which dates you are free on the event’s doodle page.
We hope it will be a good opportunity to learn a bit more about visualisation software packages, to exchange ideas, and possibly to start to work on some new projects! If all goes well, we’ll arrange to meet up on a (semi) regular basis!
Open Textbooks Statement to Make Textbooks Affordable
April 16th, 2008
Make Textbooks Affordable, a campaign composed of Student Associations and Public Interest Research Groups from across the US, yesterday released a statement in support of open textbooks signed by 1000 academics. From the press release:
Open textbooks are complete, reviewed textbooks written by academics that can be used online at no cost and printed for a small cost. What sets them apart from conventional textbooks is their open license, which allows instructors and students flexibility to use, customize and print the textbook. Open textbooks are already used at some of the nation’s most prestigious institutions - including Harvard, Caltech and Yale - and the nation’s largest institutions - including the California community colleges and the Arizona State University system.
“Open textbooks are comparable, affordable and flexible alternatives to traditional expensive textbooks,” said Professor Linda Bisson, Chair of the Enology and Viticulture Department at the University of California, Davis. “Not only do they save students money, but they provide instructors with a high-quality textbook that they can customize to meet their needs.”
Textbooks cost students an average of $900 per year, which is a quarter of tuition at an average four-year public university and nearly three-quarters of tuition at a community college, according to a study conducted by the Government Accountability Office (GAO).
“Textbooks can price students out of higher education. With costs rising faster than inflation and tuition, some students are faced with the difficult choice to drop out, take on additional debt, or undercut their own learning by not purchasing textbooks,” said Nicole Allen, Textbooks Advocate for The Student PIRGs.
Research conducted by The Student PIRGs identifies publisher tactics as the primary cause of escalating prices. Bundling textbooks with unnecessary supplements forces students to purchase items they do not need; unnecessary new editions undermine the used book market; and withholding critical price information keeps faculty in the dark.
“As faculty members, our top priority is to choose the textbook that is best for our students. We share concerns about affordability, and face similar frustrations with publisher practices,” said Sandra Schroeder, Chair of the American Federation of Teachers Higher Education Program and Policy Council. “Open textbooks and other affordable options, when appropriate for a course, are a win-win for everyone.”
On the What are Open Textbooks? page, they mention our Open Text Book project, and the Open Knowledge Definition - which is great to see! Its good that they emphasise the importance of licensing that permits people to “reproduce, customize, or distribute” as well as access.
However while they allude to Creative Commons licenses - they don’t explicitly distinguish between those licenses which are open (Creative Commons Attribution and Attribution Sharealike), and those which are not (Creative Commons licenses with No Derivatives or Non-commercial options).
While the latter do afford people more choice about what can be done with their work - there are problems with interoperability, and do not serve well as the basis of an ecosystem of textbooks and textbook content that may be built upon, modified and redistributed without restriction. For example, publishers may not have the incentive to add value to existing content if they would be unable to re-distribute this in a commercial context.
Nevertheless its fantastic to see growing support for open textbooks!
Open Data Going Mainstream?
April 10th, 2008
Bret Taylor’s recent post entitled “We Need a Wikipedia for Data” has been garnering a lot of attention around the blogosphere. While his suggestions are not particularly novel, the post and the attention it has garnered, is, I think, indicative of the growing interests in the issues of (open) data and its importance for the development of related services and products.
While generally in agreement with Bret’s arguments, there are a few differences that are worth raising. First Bret appears to favour some kind of centralized repository that everyone can read from and write to:
To this end, I think we should create a Wikipedia for data: a global database for all of these important data sources to which we all contribute and that anyone can use.
As readers of this blog will know, we’re sceptical of this ‘one ring to rule them all’ approach. In this regard, it is also important to distinguish finding material, parsing it, and plugging it together, issues that got rather run together in the surrounding discussion. As I wrote in a comment to Bret’s post:
There seem to be several distinct issues you (and your commenters) are concerned with:
1. Discoverability of datasets. For this you want a registry of some kind and this is exactly what the Comprehensive Knowledge Archive Network (CKAN) is designed to do. …
2. ‘Developing’ data particularly using many contributors and a versioning (wiki-like) model. This seems a general problem and one which I wrote about in this post on the collaborative development of data back in February last year. Since then various projects have launched or developed which attempt to address this issue, even if only partially (e.g. Freebase, Swivel, Numbrary, http://www.openeconomics.net …). This then leads into:
3. Componentizing data so that one can easily plug different datasets together rather than having to aggregate data together in one big place (crudely: ‘One Ring to Rule them All’ vs. ‘Small Pieces, Loosely Joined’). After all it seems unlikely that any one organization, however large, can hold ‘all the data’, and in ay case doing so would negate the benefits of having ‘many minds’ working on a problem. It is our hope that CKAN would start to facilitate the kind of packaging that one frequently observes in software but is, as yet, fairly rare for knowledge (data/content/…). More on this can be found in this blog post on componentization plus the slides from our presentation at XTech.
To conclude, I definitely agree about the importance of having more open data and making it easier to find and use though I’m hoping that it will take a more decentralized and componentized form than simply a ‘wikipedia’ for data. More important though than any details is the fact that this kind of interest from a wider audience indicates that issues of data openness and production are going mainstream — something we as a community should strongly welcome.
OKCon 2008 Documentation and Open Knowledge Local Groups!
April 2nd, 2008

We’re pleased to announce that audio, images and slides from OKCon 2008 are now available at the Post-Event Information page.
Most of the material can be obtained from the OKF subversion repository.
If you’ve blogged the event or have pictures or the like, please let us know and we’ll post a link from the Post-Event page. We are also able to host any further documentation in the repository.
Many thanks to all of you who came to speak, present and participate! We had a great day and very much enjoyed the talks, demos and conversations that took place throughout the day.
We’ve now set up a wiki page for local Open Knowledge groups - to arrange meetups, forums and other activities:
In addition to the Cambridge group, which has been around for a few years, we are in the process of creating groups in London and Oxford. If you’d like to get involved in any of these, or you’d like to set up your own local group - don’t hesitate to get in touch!
Free our Bills!
March 27th, 2008

Free Our Bills! is a campaign led by a cheeky platypus, just escaping from the portcullis of Parliament. Sign up now, or read on…
Sometimes data being free isn’t good enough - it needs to be released in a properly structured format. If you want to reproduce the text of Bills (proposed new laws in the UK), you can get a reasonably good click-use license and go for it.
However, the PDF or HTML you get is not very intelligible to machines. For example, consider the current version of the controversial Human Fertilisation and Embryology Bill. It contains lots of amendments of an earlier 1990 act, and it is very hard to follow without being able to see how those amendments alter the earlier act. As the data isn’t structured, nobody can easily make a user interface to do this. If the Bill was published in a 21 century way, then lots of people could and would do so. This is just one example - there are lots of other ways the data for bills and amendments could be better structured, and more timely.
It’s an esoteric campaign, but a very important one. Having good quality law is vital to all of us. So please do sign up now, and help get Parliament to publish Bills better!
Public Domain Dedication & License (PDDL) v.1.0 released at OKCon!
March 18th, 2008
Jordan Hatcher, of opencontentlawyer.com and chair of the Advisory Council for the Open Knowledge Definition took the Public Domain Dedication & License out of beta on Saturday at OKCon.
The PDDL (which we blogged about in December) was initially sponsored by Talis and is specifically aimed at providing a suitable license for open data — taking account of rights in databases, such as those created by the EU Database Directive. As Jordan’s announcement states - the license is now ready for use. This is great news for producers and promoters of open data.
