Welcome to the SAS-LeG Web Site
Software As Service for the varying needs of Local eGovernments (SAS-LeG) is a joint project of the University of Groningen, Cordys and local municipalities of the north of the Netherlands. The project aims to find solutions to an acute problem of the Dutch municipalities over the past years: effective e-Government. The municipalities need to provide more and more digital services to the citizens. As a result they need to develop numerous and complex software systems to implement these e-services. The SAS-LEG project proposes to use the Software as Service (SaS) principle in order to implement the law once and offer it as a customizable service to several municipalities. This is basic research funded by the Dutch National research council (NWO) in its software engineering programme (Jacquard).
Introduction
The importance of E-Government for the highly evolved and technology-based societies of today is apparent. More and more documents of every kind exist only in their electronic form and are shared through similar means. In a lot of cases even the physical presence of the involved parties isn’t required. Despite all of this, practical implementations of E-Government are lacking.
Service Oriented Architectures are considered to be the new paradigm for developing flexible and dynamic software solutions by using loose coupling of services with operating systems, programming languages and other components of various platforms. The integration of these interoperable services around a business process allows systems development in environments that have continuously changing requirements.In order to achieve this kind of adaptability and customization to almost every situation and the ever-changing needs of the customers/users, a characteristic which is highly requested in the E-Government field, we have to concentrate on discovering new ways and structing new sets of tenets to abide by for developing software systems that will be compatible with the open world assumption and thus able to perform even in the most competitive real-life environments.

SAS-LeG Impact
The SAS-LeG project improves business processes and software architecting practices in municipalities. However, the issues in municipalities can be found in other areas of the Dutch society. For example, Dutch hospitals need to implement new business processes and ICT to accommodate new laws, similar to municipalities. Therefore, six persons (including one SAS-LeG member) recently founded 'AMD Medicine Direct' at the Startup Weekend in Groningen, a start-up aiming at reducing the number of avoidable accidents in Dutch hospitals, by also improving business processes and the software architecture in healthcare.

NWO video on SAS-LeG
A while ago we had some cameras pointed at us for an NWO promotional video. And now, the result is here. It explains the project in detail through interviews with a number of SAS-LeG project members and affiliates.
SAS-LeG Prototype Demonstration
A video demonstrating the early prototype of the project was created. In this video a process is designed graphically with Cordys BOP4 and used as template process. We then provide annotations to it representing the variability (BPMN extender), then the user can provide decisions regarding variability points. The variability engine processes these and creates variant processes that are then executed in BOP4. To watch the video, please follow this link.
SAS-LeG User Meeting
The first SAS-LeG user meeting took place on Thursday June the 3rd, and was a great success. We invited several experts from different branches related to the SAS-LeG project to provide feedback on the direction of the project. Attending experts were Albert Krabbe from the municipality of Haren, Laurens Lapré from Logica and Massimo Mecella from La Sapienza University of Rome. Wijnand van Plaggenhoef and Marco van de Veen from our technological parter Cordys joined in the afternoon via WebEx. Two of the master students involved in the project, Adam Loorbach and Piet den Dulk, joined for the discussion as well. Sadly, Carsten Hentrich from Infosys and Sjoerd Meihuizen from NWO Jacquard could not be there this time, and we hope to see them for the next user meeting. For a photo report visit this link.
Vari-Arch 2010
1st International Workshop on Variability in Software Product Line Architectures Co-located with The 4th European Conference on Software Architecture (ECSA 2010) Copenhagen, Denmark.
The objective of this workshop is to bring together researchers from the software product line community and software architecture community to identify critical challenges and progress the state-of-the-art on variability in software product line architectures.
