Optimization of E-service Development for Latvian Public Sector

The development of Latvian State E-service was started in January, 2006 (Integrated State Information System (ISIS, Latvian abbreviation IVIS)). The customer and provider of the system is Secretariat of Special Assignments Minister for Electronic Government Affairs (SSAMEGA)). Since the middle of 2007 the infrastructure is accessible for E-service designers and developers. ISIS is based on Service Oriented Architecture (SOA) principles and includes many individual innovations and modern solutions. There are more than 60 E-services, which were developed using ISIS infrastructure, already accessible for Latvian inhabitants on Latvian government E-service portal (www.latvija.lv). These Eservices consist of many Web services which are developed by different organizations and published in special register. The number of E-services growths up very quick. To avoid duplication of Web services from different organizations new solution was worked out and soon will be implemented in ISIS. This and other ISIS innovations are described further in this paper.
