On publishing linked open government data

In the last years, a number of government led initiatives have been launched worldwide aiming at making government data freely available to everyone, without limiting restrictions. Linked Data has been employed by some of these as a paradigm that allows for the provision of structured, semantically enabled and linkable data on the Web. The objective of this article is to discuss how Linked Data has been used in government data provision so far and to describe an architecture that will enable the provision of integrated government data around real-world things in a decentralized manner. Moreover, an implementation of the specific architecture is described in detail employing a hypothetical use case scenario that involves real world public agencies and schools. This implementation includes among others the publishing of Linked Data on top of a relational database and inline the HTML code of a web page as well as the linking of data from distributed sources at the instance level.
