(This page uses style sheets.)
The purpose of these guidelines is twofold:
To help Administrators decide whether a migration to OSS should be undertaken.
To describe in broad technical terms how such a migration could be carried out.
The guidelines are intended to be of practical use to Administrators and so must be relevant and accurate whilst being accessible and understandable. They are not a detailed technical reference manual. The structure is intended to allow changes to be easily made in the future as experience is gained by Administrations and as changes are made to the products available.
To meet these objectives it is imperative that the content is kept up to date and that any inaccuracies are removed. To this end, comments and contributions are encouraged from readers on any part of the guidelines. Please send comments to gposs@cec.eu.int.
The guidelines do not talk about OSS in general or about the relative merits of the various licenses. This, together with a great deal of other information, can be found in the following IDA documents:

The French “Agence pour le Développement de l'Administration Électronique”, ADAE, have produced a good guide on licences, which is also available in English at:
