The needs for exchanges between Information systems are numerous and varied and are located at all levels. Several solutions for electronic transmitting dematerialized documents are available today on the market; however, these solutions are seldom interoperable or reusable without additional cost to transport other data flows.
The French government through the voice of the DGME (Direction Générale pour la Modernisation de l’Etat) has recently published the “PRotocole d’Echanges Standard et Ouvert” 1.0 (aka PRESTO) specification. The PRESTO protocol is a secure and reliable transport protocol that aims at providing a generic message exchange layer for exchanging potentially any e-gov messages in the context of the ADELE program for the eAdministration in France.
