The IDA Open Source Migration Guidelines - November 2003 (EN, ES, FR) 

These guidelines have been designed to help public administrators decide whether a migration to OSS should be undertaken and describe, in broad technical terms, how such a migration could be carried out. They are based on practical experience of a limited number of publicly available case studies, and cover a wide range of management and technical concerns.

Pooling Open Source Software (POSS) Feasibility Study - June 2002 (EN, ES, FR, IT)

IDA has released the results of an independent study on promoting the re-use of software owned by public administrations. The study recommended the creation of a software clearing house to which administrations can "donate" software. This facility, which would concentrate on applications specific for the needs of the public sector, could encourage the replication of good practice in e-government services.

Study into the use of OSS in the public sector - June 2001 (EN)

The 'Study into the Use of Open Source Software in the Public Sector' was conducted by Unisys Belgium following a call for tender issued in the frame of the IDA Programme. This study entails three components:

  • The OSS fact sheet  gives an overview of the situation in the spring of 2001 and an assessment of availability and potential use of OSS based solutions, by software category, as well as  a selection of about 100 typical OSS solutions;
  • The second part of the study focuses on OSS usage and experience made in six European countries (Belgium, France, Spain, Germany, Italy, Sweden) and in the European Union administration;
  • The third part gives an overview of the OSS market structure, with opportunities and issues related to the use of OSS solutions.
