The use of Linked Open Data plays an important role in the process of opening government and public administration. Although the possibilities of Linked Data can provide numerous benefits in governmental processes; the adoption of the new technology involves a number of barriers, because its effective use requires complex knowledge and skills drawn from many disciplines. To promote the spread of Linked Open Data in the government there is a definite need for well-developed methodologies and guidelines of Linked Open Data technology. Our main objective is to promote the use of open Linked Data technology in the governmental sector. In this context the publication reveals the most important definitions related to Linked Open Government Data, proposes a model for its lifecycle, analyzes the necessary Linked Open Data procedures and methodologies from technological point of view focusing on governmental usage and collects the different architectural design models behind Linked Data publishing and applications.
