This document describes a study that aimed to map the universe of commons-based peer production (CBPP) cases. Researchers created a directory of over 350 CBPP cases and filtered it to a final database of 302 cases. Preliminary results are presented on the distribution of cases by country, year, activity area, collaboration type, infrastructure provider, content licenses, community size, and social media use. The study finds diversity in CBPP cases and some cases represent "pure CBPP" while others are hybrid models.

Previous researches?
•How do you map this emerging type of organizations?
•How do you sample and categorized these diversity of organizations?
The main aim is to identify factors that generate online reputation and value
•Preceding work has mainly focus on the functioning of single casesand very similar cases.
•Our research is part of one of the few studies that analyse diversity of CBPP cases.

Methods and criteria to create the first map of the CBPP universe
September 25, 2014
•We applied a non-proportional quota sampling.
•We ensured the inclusion of a mixed type of CBPP experiences to reflect the heterogeneity of CBPP
•Previous collaborative experience of experts and community
•We create a list of more of 350 cases (directory.p2pvalue.eu/)
•From this list we filter out all cases that failed to match thedefinition criteria of CBPP

Methods and criteria to create the first map of the CBPP universe
September 25, 2014
•Variability of the independent variables.
•Year, area of activity, type of common resource
•Cases that were mainly digitally based
•Only cases with web pages on these languages (English, Spanish, French, Catalan, Italian, Dutch and Portuguese)
•From this list we filter out all cases that failed to match thedefinition criteria of CBPP

Methods
September 25, 2014
•Collaborative production
•To create CBPP directory
•Web observation
•Approximately 40 minutes per case (reliability second coder 90%)
•Web analysis
•Web scripts (Alexa rank, Google Rank, Kred, Google search..)
•Survey between directory cases. (Information about governance)
•Only an answer rate of 20% of 340 e-mails

•The plurality of layers and dimensions that characterize this form of production .
•Some of cases are “pure CBPP” (in terms of criteria of delimitation), while others are hybrids.
•The informality that characterizes such forms of production.
