Dear SCPE readers,
The series of Workshops on Software Services (acronym WoSS) was initiated in 2010 with the goal to create a framework for presenting and discussing the recent significant developments in the field of software services. Already the first edition WoSS proved to be an open forum for academics, practitioners, and vendors, allowing them to analyze the current trends and scientific and technological challenges, such as service quality assurance, adaptability, reliability, interoperability, and automating service-oriented application construction and management. A particularity of three editions of the series is the aim to highlight the achievements of the on-going European collaborative projects subscribing to European Commission FP7-ICT programme and the activities of the teams from new member states in software services.
The first edition of WoSS from September 2010, dedicated to Frameworks and Platforms, has attracted 31 contributions, part of them being accepted for presentation at the workshop and later on publication in the IEEE Computer Press proceedings of the SYNASC 2010 symposium.
This special issue presents the extended versions of 10 selected papers. The new papers are including extensive description of their contributions as well as novel approaches and results.
As an entire, the special issue intends to present an image of the current status of the research activities in the field of software services. Therefore the subjects are varying from workflow to resource management, from data migration to access control, from quality of services to public services, from file searching to trust, from surveillance applications to automated service compositions.
The last paper of this issue is part of the batch of papers presented in the previous number of SCPE 11(4), related to Network Management in Distributed Systems, but is presented in this number since its content matched better the aims of the current issue.
