description
When building reliable data-driven applications for local governments to interact with public servants or citizens, data publishers and consumers have to be sure that the applied data structure and schema definition are accurate and lead to reusable data. To understand the characteristics of reusable local government data, we motivate how the process of developing a semantically enriched exchange standard contributes to resolving this issue. This standard is used, for example, to describe contact information for public services which supports a representative pilot for opening up a variety of local government data. Our main finding after implementing this pilot is that converging on semantics and specifying detailed use of the model that forms the core of such a standard leads to reusable government data.

Linked Data suitable for data management for local governments
Showed applicability of Linked Data in a first pilot project.
Future
Measure how well agreeing on semantics proves to be useful in tackling issues on
converging semantics and reusable government data.
Linked Open Data community should keep advocating this process
and motivate governments to use it as main data publish & exchange system
