5th International Workshop on Web APIs and Service Mashups (Mashups 2011)

Associated with the 9th European Conference on Web Services (ECOWS) 2011
Lugano, Switzerland, 14 September 2011


Service computing and Web 2.0 are converging into a programmable as well as composable Web. This development provides the foundation for Service Mashups — compositions of Web APIs, Web content and Web data sources. The result is a novel class of diversified, agile and interactive software systems that provide rich user experience and allow new fields of application.

However, the integration of service computing and Web 2.0 technologies exposes various complexities like programming models and methodologies, service models that are well-suited for mashups, platforms and ergonomics in different operational contexts, as well as economic and social environments. Addressing some or all of these issues is an ongoing area of research and innovation, as new platforms for service delivery and service implementation constantly enter the marketplace.

The Mashups 2011 workshop solicits contributions addressing these issues and aims to bring together various relevant communities from academia and industry working on a) mashup-based applications, b) generic mashup tools, platforms and infrastructure, c) cross-cutting concerns of software service engineering and d) related topics from areas like social networking or economics.

Mashups 2011 continues the tradition of four previous events (2007 in Vienna, 2008 in Sydney, 2009 in Orlando, and 2010 in Cyprus) that not only offer a broad range of papers in this space, but also present keynote speakers from leading industry groups currently offering mashup tools and platforms.


Contributors are invited to submit original research papers addressing relevant aspects of mashup applications, technologies and engineering. Topics of interest include, but are not limited to, the following:

  • Languages, frameworks, and platforms for the design, implementation, testing and maintenance of services mashups, including dynamic languages and frameworks.
  • New approaches to mashup construction: data flow-, document-, spreadsheet- and process-oriented mashups, end-user mashup development, mashups in the cloud.
  • Novel applications of mashups, e.g., mobile, location-aware or wiki-based.
  • Specific service mashup application and technology examples with respect to design, architecture, implementation, usability and user-experience.
  • Mashups within social software platforms, e.g., OpenSocial or Facebook.
  • Mashups within and across enterprises.
  • Quality of service and mashups: performance, reliability, security privacy or other non-functional aspects.
  • Analysis of and experience with services mashups (creation, deployment, and usage) from social and economical perspectives; services markets and marketplaces, digital communities, pricing and contracting models.
  • Experience reports on short-term and long-term maintenance and evolution of mashups.


  • Submission Deadline: June 27, 2011
  • Notification Due: July 15, 2011
  • Final Version Due: August 12, 2011
  • Workshop Date: September 14, 2011


Authors are invited to submit original, previously unpublished research papers. Two kinds of contributions are sought: short position papers (not to exceed 4 pages) describing particular challenges or experiences relevant to the scope of the workshop, and full research papers (not to exceed 8 pages) describing novel solutions to relevant problems. Papers need to comply to the following format (download file) and are to be submitted electronically in PDF format via EasyChair at

All submissions will be peer-reviewed by members of the international program committee. Paper acceptance will be based on originality, significance, technical soundness, and clarity of presentation. Accepted papers will be included in the workshop proceedings, and circulated to participants prior to the event. Accepted workshop papers will be published as part of the ACM Digital Library (under negotiation).

At least one author of an accepted paper must register and participate in the workshop. Registration is subject to the terms, conditions and procedure of the main ECOWS conference to be found on their Web site at
