An Architecture for E-Government Social Web Applications

With the advent Web 2.0 a large number of social web applications, such as Blogs, Wikis and micro blogging services such as Twitter have emerged. These applications are often available as open source software or free services. The use of social web applications in public administration offers the chance to leverage the work of public administrations and to connect public authorities. Unfortunately, available systems do not meet the requirements of public administration. They are implemented in scripting languages like PHP or Perl and do not scale well and also suffer from security issues. Furthermore, e-government applications have to be compliant to auditing standards, guarantee accessibility etc. In this paper a scalable and extensible architecture especially crafted for the use of Web 2.0 applications in public administration is presented. Special emphasis is given to the topic of accessibility.
