	abstract = {Existing studies show that open source projects may enjoy high levels of socio-technical congruence despite their open and distributed character. Such observations are yet to be confirmed in the case of larger open source ecosystems in which developers contribute to different projects within the ecosystem. In this paper, we empirically study the relationships between the developer coordination activities and the project dependency structure in the Ruby ecosystem. Our motivation is to verify whether the ecosystem context maintains the high socio-technical congruence levels observed in many smaller scale FLOSS (Free/Libre Open Source Software) projects. Our study results show that the collaboration pattern among the developers in Ruby ecosystem is not necessarily shaped by the communication needs indicated by the dependencies among the ecosystem projects.

	note = {"We first collected meta-data on the 21,094 most highly ranked Java projects on 2009-03-17 from SourceForge for which it was possible to get such data. Here {\textquotedblleft}Java projects{\textquotedblright} were defined as projects belonging to {\textquotedblleft}trove{\textquotedblright} 198 at SourceForge and {\textquotedblleft}rank{\textquotedblright} was the SourceForge ranking of projects. The data consisted of characteristics such as number of bugs, time of latest file upload, number of developers, number of open bugs, and SourceForge {\textquotedblleft}rank{\textquotedblright}."

	abstract = {Software architecture is concerned with the structure of software systems and is generally agreed to influence software quality. Even so, little empirical research has been performed on the relationship between software architecture and software quality. Basedon 1,141 open source Java projects, we calculate three software architecture metrics (measuring classes per package, normalizeddistance, and a new metric introduced by us concerning the excess of coupling degree) and analyze to which extent these metricsare related to product metrics (defect ratio, download rate, methods per class, and method complexity). We conclude that there area number of significant relationships between product metrics and architecture metrics.  In particular, the number of open defectsdepends significantly on all our architecture measures.},
