Outline 
● Drupal as a Commons-Based Peer Production 
community 
● Activity as unit of analysis and Activity Theory 
● Pilot Study: understanding contribution. Future work 
● Summary and questions 
OpenSym 2014 – Doctoral www.p2pvalue.eu Symposium – 26.08.2014
What is Drupal? 
● Free software content management framework 
● Very modular: think of it as a “Lego”. Dozens of “core modules”, 
+27k contributed modules 
● Powering 2% websites worldwide (W3Techs, 2014) 
● Employed in complex and high traffic websites: whitehouse.gov, 
mtv.co.uk, economist.com, etc. 
OpenSym 2014 – Doctoral www.p2pvalue.eu Symposium – 26.08.2014
What is Drupal?: the Drupal community 
● Started as a personal project of a student 
● Code released in 2001 under a GPL 
● Currently +1M users registered at Drupal.org, +30k code 
contributors (Drupal.org, 2014a) 
● Hundreds of local F2F events, dozens of camps and 
cons in 4 continents (Drupal.org, 2014b) 
OpenSym 2014 – Doctoral www.p2pvalue.eu Symposium – 26.08.2014
What are the commons? 
● The commons: as a resource or good shared by a group of people that 
may be subject to social dilemmas, such as over-exploitation or 
free-riding. (Hess & E. Ostrom, 2007) 
● Classification of goods according to: 
● Excludability: feasible to prevent its access to it 
● Rivalry: its use or consumption prevents or affects 
the consumption by others 
Rival Non-Rival 
Excludable Private 
goods. E.g.: 
bread 
Toll goods. 
E.g.: cable 
TV 
Non-exclud 
able 
Common 
Pool 
Resources 
E.g.: fish 
taken from 
the ocean 
Public 
goods 
E.g.: 
lighthouse, 
Free 
Software 
V. Ostrom and E. Ostrom (1999) 
OpenSym 2014 – Doctoral www.p2pvalue.eu Symposium – 26.08.2014
What are the commons? 
● Furthermore, some of these goods are anti-rival: the more people 
use them, the more utility each person receives (e.g.: Free 
software). Weber (2004) 
● One more dimension: the scope of the ownership: ”Those goods 
that belong to everyone and no one at the same time, therefore 
not following the rules of the market” 
Lafuente et al. (2007) 
OpenSym 2014 – Doctoral www.p2pvalue.eu Symposium – 26.08.2014
The Drupal goods as a commons 
● Anti-rival: its use by a person increases the value for other users 
● Non-excludable: accessibility is protected as part of the licenses applied for 
the code, the contents created in the community, etc. 
● Global : the ownership does not belong 
to any individual or state, as protected by the 
licenses chosen (exception: the trademark) 
OpenSym 2014 – Doctoral www.p2pvalue.eu Symposium – 26.08.2014
What is Commons-Based Peer Production? 
● A new model of socio-economic production in which groups of loosely 
connected individuals cooperate with each other to produce meaningful 
products without a traditional hierarchical organisation (Benkler, 2006) 
● Emerging model (see http://directory.p2pvalue.eu/) 
OpenSym 2014 – Doctoral www.p2pvalue.eu Symposium – 26.08.2014
Drupal as a CBPP community 
● Ongoing discussion on the differences between CBPP, Peer Production, the 
delimitation criteria, etc. 
● Drupal as a community whose mode of production is (P2Pvalue, 2014): 
● Collaborative process 
● Peer-based: different levels of structure depending on the process, but not mainly 
based on contractual obligations neither forms of coercion 
● Commons-process: process driven by the general interest, results in openness of 
the resources 
● Favouring reproducibility: via Free Software/CC licenses, exchange of practices, 
etc. 
OpenSym 2014 – Doctoral www.p2pvalue.eu Symposium – 26.08.2014
Contribution activities as unit of analysis 
● Previous studies looked either at the individuals or at the whole community 
(e.g.: motivations to contribute, structure of the community, etc.). Huang, Le 
& Panchal (2011), Nordin and Meir (2013), Sims, J. P. (2013) 
● My approach is to look at activities as unit of analysis (using Activity Theory 
as a framework), using a virtual ethnographic approach. 
● Understand processes and dynamics 
● Implies to understand deeply what contribution means: pilot study 
OpenSym 2014 – Doctoral www.p2pvalue.eu Symposium – 26.08.2014
What is Activity Theory? 
● Historical roots in the idea of object-oriented activity and relationship 
between object and subject (Marx, 1845): subject produces herself by 
producing the object 
● 1st AT generation [1920s]: Soviet Cultural-historical psychology - 
Vygotsky, Leont'ev,.. 
● “Mediated action”: by collaborating in the development of activities 
with other humans, meanings, social norms, artifacts, etc. are 
internalised by the individuals. (Vygotsky, 1979). 
OpenSym 2014 – Doctoral www.p2pvalue.eu Symposium – 26.08.2014
What is Activity Theory? 
● 2nd AT generation [1980s]: Engeström and the AT Scandinavian school 
● Human activity system as unit of analysis: dynamic, culturally-mediated, 
specific to human-beings, analysable in its context. (Engeström, 1987). 
● Extends Leont'ev's model: adding the rules that regulate the activity, 
community sharing the interest and the division of labour. (Engeström, 
1987). 
OpenSym 2014 – Doctoral www.p2pvalue.eu Symposium – 26.08.2014
What is Activity Theory? 
● Subject: the actors that performed the activity and who are subjected to 
the internalisation process. 
● Instruments, mediating artifacts: the tools employed by the actors in the 
system. Influence on actors, structure and change 
● Object: the element to which activity is directed towards. Transformed as 
the activity progresses, possesses social and cultural properties. 
● Rules: they are the explicit and implicit rules which regulate the activity in 
the system. 
● Community: they are all the actors involved in the system. 
● Division of labour : it represents the distribution 
of processes between the actors of the system. 
OpenSym 2014 – Doctoral www.p2pvalue.eu Symposium – 26.08.2014
Dev. Of contrib modules under AT lenses 
OpenSym 2014 – Doctoral www.p2pvalue.eu Symposium – 26.08.2014
Pilot study: understanding contribution 
● Pilot study (ongoing) identify what activities are perceived as contributions and 
some of its outcomes (for further exploration) 
● What activities are perceived as contributions? Do the “official” meanings match 
the perceptions of the members of the community? Do perceptions vary 
according to degree of experience? And the role/specialty? 
● Virtual ethnographic perspective (Hine, 2000): study of online communities and its 
culture. Online and offline. Qualitative. Inductive approach. 
OpenSym 2014 – Doctoral www.p2pvalue.eu Symposium – 26.08.2014
Pilot study: methods and data outcomes 
● Methods: 
● Participant-observation: online and offline (local, national, international 
events). Full-field notes 
● Qualitative semi-structured interviews: Drupal community members, 
following a strategic sampling. Transcriptions. 
● Documentary research: selection and pre-coding of materials from Drupal 
Planet (+5k links), including blog posts, podcasts, videos, etc. 
● Data analysis: Qualitative content analysis, using CAQDAS 
OpenSym 2014 – Doctoral www.p2pvalue.eu Symposium – 26.08.2014
Pilot study: preliminary insights 
● Contribution beyond source code, in a code-centric community. Nordin and Meir 
(2013), Sims (2013), Zilouchian, Bongen and Twidale (2011) 
● Role of affective labour (Hardt, 1999) as outcomes of some of the activities: immaterial 
labour in human interaction that creates or modifies emotional experiences. Produces 
satisfaction, passion, sense of community, etc. 
● The lifeblood of the commons (Bollier, 2014) 
● Unevenly represented in the main platform of collaboration? 
OpenSym 2014 – Doctoral www.p2pvalue.eu Symposium – 26.08.2014
Future work 
● Select and deeply study some 
of the activities identified 
in the pilot study 
(preliminary proposal) 
OpenSym 2014 – Doctoral www.p2pvalue.eu Symposium – 26.08.2014
Summary 
● Drupal community (diverse, complex, etc.) as a case study 
of CBPP, to study processes and dynamics 
● AT as lenses, using a virtual ethnographic approach 
● Preliminary insights of the pilot study and thoughts on 
possible future work

Drupal as a Commons-Based Peer Production community: a sociological perspective

  • 1. Drupal as a case of Commons-Based Peer Production community: a sociological perspective David Rozas University of Surrey This work was partially supported by the Framework programme FP7-ICT-2013-10 of the European Commission through project P2Pvalue (grant no.: 610961). OpenSym 2014 – Doctoral www.p2pvalue.eu Symposium – 26.08.2014
  • 2. Who am I? ● Areas of interest: Free Software, Commons-Based Peer Production, social computing, etc. ● Working as a Drupal developer for the past 4 years. Previously working with Django, Moodle, etc. ● Previous background in Computer Science (@URJC [Spain], @NTNU [Norway]) ● Started PhD in Sociology @UniS [UK] in October 2013 ● Collaborating with the FP7 EU project P2Pvalue ● +info|contact: ● @drozas ● www.davidrozas.com || drozas@surrey.ac.uk OpenSym 2014 – Doctoral www.p2pvalue.eu Symposium – 26.08.2014
  • 3. Outline ● Drupal as a Commons-Based Peer Production community ● Activity as unit of analysis and Activity Theory ● Pilot Study: understanding contribution. Future work ● Summary and questions OpenSym 2014 – Doctoral www.p2pvalue.eu Symposium – 26.08.2014
  • 4. What is Drupal? ● Free software content management framework ● Very modular: think of it as a “Lego”. Dozens of “core modules”, +27k contributed modules ● Powering 2% websites worldwide (W3Techs, 2014) ● Employed in complex and high traffic websites: whitehouse.gov, mtv.co.uk, economist.com, etc. OpenSym 2014 – Doctoral www.p2pvalue.eu Symposium – 26.08.2014
  • 5. What is Drupal?: the Drupal community ● Started as a personal project of a student ● Code released in 2001 under a GPL ● Currently +1M users registered at Drupal.org, +30k code contributors (Drupal.org, 2014a) ● Hundreds of local F2F events, dozens of camps and cons in 4 continents (Drupal.org, 2014b) OpenSym 2014 – Doctoral www.p2pvalue.eu Symposium – 26.08.2014
  • 6. What are the commons? ● The commons: as a resource or good shared by a group of people that may be subject to social dilemmas, such as over-exploitation or free-riding. (Hess & E. Ostrom, 2007) ● Classification of goods according to: ● Excludability: feasible to prevent its access to it ● Rivalry: its use or consumption prevents or affects the consumption by others Rival Non-Rival Excludable Private goods. E.g.: bread Toll goods. E.g.: cable TV Non-exclud able Common Pool Resources E.g.: fish taken from the ocean Public goods E.g.: lighthouse, Free Software V. Ostrom and E. Ostrom (1999) OpenSym 2014 – Doctoral www.p2pvalue.eu Symposium – 26.08.2014
  • 7. What are the commons? ● Furthermore, some of these goods are anti-rival: the more people use them, the more utility each person receives (e.g.: Free software). Weber (2004) ● One more dimension: the scope of the ownership: ”Those goods that belong to everyone and no one at the same time, therefore not following the rules of the market” Lafuente et al. (2007) OpenSym 2014 – Doctoral www.p2pvalue.eu Symposium – 26.08.2014
  • 8. The Drupal goods as a commons ● Anti-rival: its use by a person increases the value for other users ● Non-excludable: accessibility is protected as part of the licenses applied for the code, the contents created in the community, etc. ● Global : the ownership does not belong to any individual or state, as protected by the licenses chosen (exception: the trademark) OpenSym 2014 – Doctoral www.p2pvalue.eu Symposium – 26.08.2014
  • 9. What is Commons-Based Peer Production? ● A new model of socio-economic production in which groups of loosely connected individuals cooperate with each other to produce meaningful products without a traditional hierarchical organisation (Benkler, 2006) ● Emerging model (see http://directory.p2pvalue.eu/) OpenSym 2014 – Doctoral www.p2pvalue.eu Symposium – 26.08.2014
  • 10. Drupal as a CBPP community ● Ongoing discussion on the differences between CBPP, Peer Production, the delimitation criteria, etc. ● Drupal as a community whose mode of production is (P2Pvalue, 2014): ● Collaborative process ● Peer-based: different levels of structure depending on the process, but not mainly based on contractual obligations neither forms of coercion ● Commons-process: process driven by the general interest, results in openness of the resources ● Favouring reproducibility: via Free Software/CC licenses, exchange of practices, etc. OpenSym 2014 – Doctoral www.p2pvalue.eu Symposium – 26.08.2014
  • 11. Contribution activities as unit of analysis ● Previous studies looked either at the individuals or at the whole community (e.g.: motivations to contribute, structure of the community, etc.). Huang, Le & Panchal (2011), Nordin and Meir (2013), Sims, J. P. (2013) ● My approach is to look at activities as unit of analysis (using Activity Theory as a framework), using a virtual ethnographic approach. ● Understand processes and dynamics ● Implies to understand deeply what contribution means: pilot study OpenSym 2014 – Doctoral www.p2pvalue.eu Symposium – 26.08.2014
  • 12. What is Activity Theory? ● Historical roots in the idea of object-oriented activity and relationship between object and subject (Marx, 1845): subject produces herself by producing the object ● 1st AT generation [1920s]: Soviet Cultural-historical psychology - Vygotsky, Leont'ev,.. ● “Mediated action”: by collaborating in the development of activities with other humans, meanings, social norms, artifacts, etc. are internalised by the individuals. (Vygotsky, 1979). OpenSym 2014 – Doctoral www.p2pvalue.eu Symposium – 26.08.2014
  • 13. What is Activity Theory? ● 2nd AT generation [1980s]: Engeström and the AT Scandinavian school ● Human activity system as unit of analysis: dynamic, culturally-mediated, specific to human-beings, analysable in its context. (Engeström, 1987). ● Extends Leont'ev's model: adding the rules that regulate the activity, community sharing the interest and the division of labour. (Engeström, 1987). OpenSym 2014 – Doctoral www.p2pvalue.eu Symposium – 26.08.2014
  • 14. What is Activity Theory? ● Subject: the actors that performed the activity and who are subjected to the internalisation process. ● Instruments, mediating artifacts: the tools employed by the actors in the system. Influence on actors, structure and change ● Object: the element to which activity is directed towards. Transformed as the activity progresses, possesses social and cultural properties. ● Rules: they are the explicit and implicit rules which regulate the activity in the system. ● Community: they are all the actors involved in the system. ● Division of labour : it represents the distribution of processes between the actors of the system. OpenSym 2014 – Doctoral www.p2pvalue.eu Symposium – 26.08.2014
  • 15. Dev. Of contrib modules under AT lenses OpenSym 2014 – Doctoral www.p2pvalue.eu Symposium – 26.08.2014
  • 16. Pilot study: understanding contribution ● Pilot study (ongoing) identify what activities are perceived as contributions and some of its outcomes (for further exploration) ● What activities are perceived as contributions? Do the “official” meanings match the perceptions of the members of the community? Do perceptions vary according to degree of experience? And the role/specialty? ● Virtual ethnographic perspective (Hine, 2000): study of online communities and its culture. Online and offline. Qualitative. Inductive approach. OpenSym 2014 – Doctoral www.p2pvalue.eu Symposium – 26.08.2014
  • 17. Pilot study: methods and data outcomes ● Methods: ● Participant-observation: online and offline (local, national, international events). Full-field notes ● Qualitative semi-structured interviews: Drupal community members, following a strategic sampling.
