The OSOR (Open Source Observatory and Repository), maintained by the European Commission, has recently published the Procurement and Open Source Software Guideline document, which describes motivations for the adoption of FLOSS for governmental entities as well as practical aspects to consider during the procurement process for FLOSS-based solutions.
The document was commissioned by the European Commission, which is working to standardize public computacional services and is researching the good practices surrounding FLOSS. The final delivery of this document promises to be an important step towards a wider and faster adoption of FLOSS on the governmental level within the European Union.
