We develop a framework for organizing the literature based on the input-mediator-output- input (IMOI) model from the small groups literature. We present a quantitative summary of articles selected for the review and then discuss findings of this literature categorized into issues pertaining to inputs (e.g., member characteristics, technology use and project characteristics), processes (software development and social processes), emergent states (e.g., trust and task related states) and outputs (e.g. team performance, FLOSS implementation and project evolution). Based on this review, we suggest topics for future research, as well as identifying methodological and theoretical issues for future inquiry in this area, including issues relating to sampling and the need for more longitudinal studies.},

	abstract = {<p>There is an exciting natural match between social network analysis methods and the growth of data sources produced by social interactions via information technologies, from online communities to corporate information systems. Information Systems researchers have not been slow to embrace this combination of method and data. Such systems increasingly provide "digital trace data" that provide new research opportunities. Yet digital trace data are substantively different from the survey and interview data for which network analysis measures and interpretations were originally developed. This paper examines ten validity issues associated with the combination of data digital trace data and social network analysis methods, with examples from the IS literature, to provide recommendations for improving the validity of research using this combination.</p>},

We recreated the analysis using a comparable data set from 2006, with one additional point in time. We also expanded upon the original results by applying different criteria for evaluating the rate of new software releases for sustainability of project activity. We discuss the points of convergence and divergence from the original work from these extensions of the classification, and their implications for studying FLOSS development using archival data. The paper contributes new analysis of operationalizing success in FLOSS projects, with discussion of implications of the findings.},

	abstract = {This paper presents a novel method and algorithm to measure the size of an open source project{\textquoteright}s user base and the level of potential user interest that it generates. Previously unavailable download data at a daily resolution confirms hypothesized patterns related to release cycles. In short, regular users rapidly download the software after a new release giving a way to measure the active user base. In contrast, potential new users download the application independently of the release cycle, and the daily download figures tend to plateau at this rate when a release has not been made for some time. An algorithm for estimating these measures from download time series is demonstrated and the measures are examined over time in two open source projects.},

For purposes of background and justification, the paper first introduces eResearch as increasingly practiced in fields such as astrophysics and biology, then contrasts the practice of research on free and open source software. After outlining the suitable public data sources the paper introduces a class of tools known as scientific workflow frameworks, specifically focusing on one---Taverna---and introducing its features. To further explain the tool a complete workflow used for original research on FLOSS is described and the agenda for the live demonstration is outlined.

	abstract = {We are working to introduce the ideas of eResearch to a multi-disciplinary research domain: those researchers examining Free/Libre and Open Source Software (FLOSS) and its development (Howison, Wiggins, \& Crowston, 2008). The first phase of this work focused on building a repository for data on FLOSS teams, FLOSSmole (Howison, Conklin, \& Crowston, 2006), and collaborating with other nascent data repositories in the field. Recently we have begun a second phase, which is to introduce another established principle of eResearch, that of broader collaboration through shared workflows accessing these data repositories. To provide an example of the potential value of this principle, we are replicating seminal FLOSS papers using eResearch approaches. This paper describes research outcomes and lessons learned from translating published literature into eResearch workflows.},
