SIGMA - SemantIc Government Mash-Up Application: Using Semantic Web Technologies to Provide Access to Governmental Data

The paper presents SIGMA (Semantic Government Mash-up Application), a platform able to create mash-ups by providing access to open governmental data. The proposed solution is based on the existing semantic Web technologies (especially RDF and SPARQL) and uses public distributed endpoints conforming to the Linked Data initiative. Also, SIGMA allows creating and deployment of independent plugins, encouraging the developers to build innovative applications, visualization solutions and mash-ups that give an improved access to the governmental data.
