Publishing of open government data brings enormous benefits both to providers and consumers. On the one hand, governments increase their transparency and enable development of smarter and richer solutions, while on the other hand it enables various stakeholders to extract new information and create value from them. In this paper we investigate applicability of open government data for economic development and creation of value from published data. Different aspects of open government data consumption are explored, such as effectiveness, transparency and quality-and how they interrelate. They are of great importance for valorisation of open government data, and we will show that leveraging economic value of OGD must be accompanied by governments' ability to make high quality OGD available.
