6th International Workshop on Web APIs and Service Mashups (Mashups 2012) at ESOCC 2012
                        19 September 2012, Bertinoro, Italy

Services computing and Web 2.0 are converging into a programmable Web today. The interaction and integration of services computing and Web 2.0 technologies, however, exposes various complexities that have to be faced. This workshop looks specifically at Services Mashups – end-user-oriented compositions of Web APIs, Web content and Web data sources.

BACKGROUND
The continuous proliferation of many Web APIs together with the social changes that are taking place in the last years are contributing to turn the Web into a programmable Web. An interesting consequence of this programmable feature is that it empowers end-user to build new data and services from the combination of resources that are available in the Web providing a higher-level value than the original exposed APIs.

A classical example of a Mashup consists in combining mapping APIs (e.g., Google Maps) and Atom data APIs (e.g. from New York Times) to provide a new service that displays listing on the map. The resulting Web applications, or mashups, add a new value to the combined Web APIs that was not initially conceived for them individually.

While mashups have taken off and 1000s of them are currently available for various purposes, there still remain various challenges and opportunities that, if properly addressed, would make mashup development more feasible and popular. Some of the main challenges are:

1. Devising programming models (languages, frameworks, platforms) for the composition of Web-accessible services and data of all kinds and architectural styles (REST, Atom, RSS, AtomPub, and SOAP/WSDL) and development of integrated user-interfaces
2. Ensuring quality of service for mashups, including performance, reliability, and security
3. Understanding social and economic factors in the creation, acceptance, and sustainability of services mashups, including software-as-services markets, services marketplaces and intermediaries, digital communities, and pricing, incentive and contracting models
4. Integrating mashups into social computing platforms, such as Facebook and OpenSocial-enabled social networks, which provide a huge user base with profiles and social graphs data
5. Scaling mashups, e.g.,  taking advantage of the cloud computing infrastructure
6. Providing the necessary primitives to secure resulting data from mashups and also ensure privacy of the original data and APIs
7. Simplifying platforms and tools to a point that mashups could be generated by end-users with minimal efforts
8. Enabling mashups for mobile platforms, such as smartphones, which also expose interesting new kind of information such as location and profile data

In this sixth edition of the Mashups Workshop we will solicit contributions addressing these issues and aim to bring together several relevant communities from academia and industry working on a) mashup-based applications, b) generic and domain-specific mashup tools, platforms and infrastructure, c) cross-cutting concerns of software service engineering and d) related topics from areas like social networking or economics.

We plan to continue the tradition of the previous Mashups workshops (2007 in Vienna, 2008 in Sydney, 2009 in Orlando, 2010 in Cyprus, 2011 in Lugano), not only selecting a broad range of papers in the space but also getting keynote speakers from leading industry groups that are currently offering mashup tools and platforms for wide-consumptions and availability.

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: dataflow-, document-, spreadsheet- and process-oriented mashups, end-user mashup development, mashups on the cloud
- Novel applications of mashups, e.g., mobile mashups, location-aware mashups, wiki-based mashups
- 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, and other non-functional aspects
- Analysis of and experience with services mashups (creation, deployment, and usage) from social and economic perspectives; services markets and marketplaces, digital communities, pricing and contracting models
- Experience reports on short-term and long-term maintenance and evolution of mashups

Peer-reviewed workshop papers will be published as part of the ACM Digital Library (Approval Pending). 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 and are to be submitted electronically in PDF format via EasyChair (http://www.easychair.org/conferences/?conf=mashups2012).
