Karsten Gerloff hat für das „Open Source Observatory and Repository (OSOR)“,einem Projekt von IDABC der EU-Kommission eine Case-Study zum Einsatz von Plone im eGovernment in Belgien geschrieben: Networks effects: Plone for Belgium and beyond.
CommunesPlone originated as an initiative to promote software cooperation between local governments in Belgium. Since its start in 2005, it has grown rapidly, with now 26 members. Organised like a FLOSS community, the group develops applications in the Plone. Taking this idea to the international level, the PloneGov project, started in June 2007, brings together 55 public bodies on four continents to produce Plone-based software that fits their needs.
