The ISA programme of the European Commission aims at fostering interoperability, sharing, and re-use of IT solutions among European public administrations. ISA’s goal is to facilitate effective and efficient collaboration between public administrations in support of cross-border and cross-level public services for citizens and businesses.
The ISA programme is managed by the European Commission’s Directorate-General for Informatics.

Given the connection between the semantic interoperability theme and the ISWC 2014 topics, ISA will be present at ISWC 2014 with a desk for presenting their initiative for all people coming from the Public Administrations.
You will find more information about the ISA programme here: http://ec.europa.eu/isa/index_en.htm.
Among other actions, ISA actively promotes semantic interoperability among EU public administrations.
