As mobility of people and business within the EU increases, cross-border digital public services are a key policy priority in the internal market. However, cross-border e-Government services are still few since a number of challenges is faced varying between semantic, organizational, legal or technical ones. Delivering cross-border services to European citizens and businesses will be difficult, if not impossible, without interoperability among European public administrations. Since cross-border services require horizontal approach, they tend to run into more barriers than services provided on national level.
e-SENS is a Large Scale Pilot (LSP) aims to make it easier to provide cross-border digital public services in Europe by development of generic and re-usable technical components for seamless electronic and multilingual communication.
