There's quite a lot of work studying the effects of licensing in free/libre open source software. You can find a number of papers on http://flosshub.org/biblio (search for license) and some of the work is summarized in review articles on FLOSS (e.g., [1]). The findings are mixed: some studies found that more restrictive licenses (i.e., GPL) led to more project popularity but others that less restrictive licenses (e.g., BSD) led to higher developer productivity. Some of the effects may be spurious, e.g., it could be that some project characteristics affect both productivity and choice of license.

Out of interest does anyone know of any research or case studies
looking at the role of open licensing in collaborative projects and
how open licensing enables/facilities collaboration?
E.g. in open content projects like Wikipedia, open data projects like
Open Street Map, or in open access research projects like the Human
Genome Project? Or - even more generally - in free/open source
software projects?

What's the average number of edits per day on English Wikipedia?
This is to frame my dissertation research -- I haven't found "edits per
day" in the stats I've looked at [1][2].
-Jodi
[1] http://toolserver.org/~emijrp/wikimediacounter/
[2] http://s23.org/wikistats/wikipedias_html.php
PS: There are other measures of work and importance I've collected.
>From the (highly recommended!) "edit sessions" paper, I get ~14,000 hours
per day [3].
Alexa & Pew provide good popularity measures [4,5], and there is of course
article count (4.2 million!).
[3] R. Stuart Geiger and Aaron Halfaker. 2013. Using edit sessions to
measure participation in Wikipedia. DOI=10.1145/2441776.2441873
http://www-users.cs.umn.edu/~halfak/publications/Using_Edit_Sessions_to_Mea…
Using the ballpark 425,000 hours/month (for 2012, English Wikipedia). Wow!
[4] Alexa: wikipedia.org is the world's 6th most popular website, 58.11% of
traffic to English Wikipedia.
http://www.alexa.com/siteinfo/wikipedia.org
[5] Pew: 53% of American Internet users look for info in Wikipedia (as of
May 2010). "The percentage of all American adults who use Wikipedia to look
for information has increased from 25% in February 2007 to 42% in May 2010.
This translates to 53% of adult internet users. "

OKCon is the annual conference for Open Knowledge (Foundation),
17th-18th September 2013, Geneva, Switzerland. It was called "OKFest"
last year. It's a well-attended and well-organized conference for anyone
interested in open knowledge, sharing, open hacking, etc.
Opportunities for Wikimedia lighting talks, workshops, etc.:
- Wikipedia Zero (see Open Development & Sustainability track)
- Analytics and open data (see Technology, Tools & Business)
(UserMetrics API? privacy? Limn?)
- SOPA/PIPA and related activities (see Evidence & Stories)
- Hack events: use their hackspace. Teach folks to make bots,
gadgets, apps, and Lua templates. Get user testing from other
open culture advocates and learn what tools they need.
This conference is eligible for subsidy of travel costs -- see
Participation Support
https://meta.wikimedia.org/wiki/Participation:Support to put in your
request.
Thanks to Sarah Stierch for the heads-up.

Hi all, reminder that the papers deadline for CSCW 2014 is a few weeks
away... (and yay about 'mania in London, btw, hope to finally see many of
you next year! :)
[Please forward to those who might be interested -- Apologies for cross-posting]
CALL FOR PAPERS, COMPUTER-SUPPORTED COOPERATIVE WORK AND SOCIAL
COMPUTING 2014 (CSCW 2014)
Baltimore, MD, Feb 15-19, 2014http://cscw.acm.org
CSCW is an international and interdisciplinary conference focused on
how technology intersects with social practices. To support diverse
and high-quality contributions, CSCW employs a two-phase review
process and does not impose an arbitrary length limit on submissions.
IMPORTANT DATES
* May 31, 5:00pm PDT, 2013: Submission due
* July 6: First-round notification (Revise & Resubmit or Reject)
* July 26, 5:00pm PDT: Revised papers due
* August 23: Final notifications
We invite submissions that detail existing practices or inform the
design or deployment of systems or introduce novel systems,
interaction techniques, or algorithms. The scope of CSCW includes, but
is not limited to, social computing and social media,
technologically-enabled or enhanced communication, education
technologies, crowdsourcing, multi-user input technologies,
collaboration, information sharing, and coordination. It includes
socio-technical activities at work, in the home, in education, in
healthcare, in the arts, for socializing and for entertainment. New
results or new ways of thinking about, studying or supporting shared
activities can be in these and related areas:
- Social and crowd computing. Studies, theories, designs, mechanisms,
systems, and/or infrastructures addressing social media, social
networking, user-generated content, wikis, blogs, online gaming,
crowdsourcing, collective intelligence, virtual worlds, collaborative
information seeking, etc.
- System design. Hardware, architectures, infrastructures, interaction
design, technical foundations, algorithms, and/or toolkits that enable
the building of new social and collaborative systems and experiences.
- Theories and models. Critical analysis or organizing theory with
clear relevance to the design or study of social and collaborative
systems.
- Empirical investigations. Findings, guidelines, and/or ethnographic
studies relating to technologies, practices, or use of communication,
collaboration, and social technologies.
- Methodologies and tools. Novel methods or combinations of approaches
and tools used in building systems or studying their use.
- Domain-specific social and collaborative applications. Including for
healthcare, transportation, gaming (for enjoyment or productivity),
ICT4D, sustainability, education, accessibility, collective
intelligence, global collaboration, or other domains.
- Collaboration systems based on emerging technologies. Mobile and
ubiquitous computing, game engines, virtual worlds, multi-touch
technologies, novel display technologies, vision and gesture
recognition systems, big data infrastructures, MOOCs, crowd labor
markets, SNSes, sensor-based environments, etc.
- Crossing boundaries. Studies, prototypes, or other investigations
that explore interactions across disciplines, distance, languages,
generations, and cultures, to help better understand how to transcend
social, temporal, and/or spatial boundaries.
Papers should detail original research contributions. Papers must
report new research results that represent a contribution to the
field. They must provide sufficient details and support for their
results and conclusions. They must cite relevant published research or
experience, highlight novel aspects of the submission, and identify
the most significant contributions. Evaluation is on the basis of
originality, significance, quality of research, quality of writing,
and contribution to conference program diversity.
SUBMISSIONS
Paper submissions must be made via the Precision Conference System. A
link to the submission site will be made available by early May.
Papers will be presented at the CSCW conference and will be included
in the conference proceedings archived in the ACM Digital Library.
CSCW does not accept submissions that were published previously in
formally reviewed publications or that are currently submitted
elsewhere.
Send queries about Paper submissions to
papers2014(a)cscw.acm.org<mailto:papers2014@cscw.acm.org>

problem than vandalism or sockpuppetry, and the spam problem is growing.
