This paper presents first results from research into open source projects from a software engineering perspective. The research methodology employed relies on public data retrieved from the CVS-repository of the GNOME project and relevant discussion groups.(...)

Modellgetriebene Softwareentwicklung MDSD mit Open Source Werkzeugen ist eine neue Ent-wicklung im Softwareengineering. Erfahrene IT Spezialisten erinnern sich an die CASE Euphorieder 90er Jahre. Die Argumentation der Verfechter beider Techniken ist ähnlich.[...]

SAP bietet mit der Komponente PI eine Enterprise Application Integration-Plattform, die als Umsetzung einer Service Orientierten Architektur verstanden werden kann.SAP und Nicht-SAP Systeme werden über Nachrichten miteinander verbunden. Dabei könnenunterschiedliche Nachrichtenformate mit...

Unter modellgetriebener Software Entwicklung (sieheMDSD (Bettin, 2004), (Stahl u. a., 2006))werden Vorgehensmodelle verstanden, bei denen Software nicht primär in einer universellen Programmiersprachewie Java, C++, C# oder Smalltalk entwickelt wird, sondern bei der...

The focus of existing open source software (OSS) research has been on how andwhy individuals and firms add to the commons of public OSS code—that is, on the“giving” side of this open innovation process. In contrast, research on thecorresponding “receiving” side of the innovation...

In this paper, we open up the black box that has been the introduction of open practices into firms’ commercial R&D strategies. Most of the existing research on the phenomenon of open innovation focuses on its interorganizational aspects. In contrast, the effect that the opening of boundaries...

In this paper, I describe and analyze the phenomenon of informal development collaborationbetween firms in the field of embedded Linux, a type of open source software. Toexplain the observed phenomenon of voluntary revealing, I develop a duopoly model ofquality competition. The central...

The link between firms engaging in open source software (OSS) development and the OSScommunity is established by individual developers. This linkage might entail a principalagentissue due to the developer’s double allegiance to firm and OSS community, and exposethe firm to the risk of losing...

This paper provides a quantitative study (N = 268) of patterns of free revealing offirm-developed innovations within embedded Linux, a type of open source software (OSS). Ifind that firms, without being obliged to do so, contribute many of their own developmentsback to public embedded Linux...
