Service Oriented Architecture Implementation in Latvia Developed Software

Currently a few integration and e-service development projects are started in Latvia. One of them is Integrated State Information System (ISIS, Latvian abbreviation IVIS), which was started in January 2006. Customer and provider of this project is the Secretariat of Special Assignments Minister for Electronic Government Affairs (SSAMEGA)). This project solution forms the infrastructure for eservice development. The infrastructure is already accessible for e-service designers and developers since the middle of 2007. There are more than 30 e-services, which were developed using ISIS infrastructure, already accessible for Latvian inhabitants on Latvian government e-service portal (www.latvija.lv). ISIS is based on Service Oriented Architecture (SOA) principles and includes many individual innovations and modern solutions. This paper describes development architecture and innovations, which are used in ISIS solution and in current government projects.
