Proceedings of the 16th international workshop on Component-oriented programming

It is our great pleasure to welcome you to the 16th International Workshop on Component-Oriented Programming -- WCOP'11. Since its first years in the nineties, WCOP has been one of the driving forces that brought component orientation into broader consciousness of the software-development community. At that time, the definitions of basic terminology were discussed and concepts were clarified. In the 2000 decade, the component idea got established in dedicated conferences (foremost CBSE, itself a former ICSE workshop) and also influenced the software architecture community strongly. During these times, WCOP evolved to a workshop for young researchers to present new ideas and to collect feedback from established members of the community. Now at the beginning of a new decade, WCOP institutionalized its role as a forum for young researchers in our community. The success of WCOP as the doctoral symposium of the CompArch federated conference shows not only that this role of WCOP is appropriate, but much more it also shows that the component idea is still vibrant and attracts young researchers internationally. In 2010, WCOP introduced the CompArch Young Investigator Award, which is given to the work of a young researcher in our community to award specifically promising work of an expected high importance. This year, the second CompArch Young Investigator Award was given to Valerio Panzica La Manna from the Politecnico di Milano, Italy, for his paper on the dynamic software update for componentbased distributed systems. WCOP symposium is a part of the federated event CompArch, this year together with "CBSE 2011: 14th International ACM Sigsoft Symposium on Component Based Software Engineering", "QoSA 2011: 7th ACM Sigsoft International Conference on the Quality of Software Architectures" and "ISARCS 2011: 2nd ACM SigSoft International Symposium on Architecting Critical Systems". Additionally, CompArch 2011 was co-located with "WICSA 2011: 9th Working International Conference on Software Architecture". We are grateful to the organizers of all these events for making CompArch a successful federated event on Component-based Software Engineering and Software Architecture.
