There is an ongoing movement in society to provide open data as an enabler for innovation and growth. As more data is passed on beyond organizational borders to trigger third party development of services, the expectations on what could be developed using open data increase. Developers have been observed to express frustration over different challenges in the wake of open data provision, such as localization issues, lack of quality in data etc. Knowledge and tools are missing to assess available open data. This absence risks ensuring continual improvement of open data markets and the management of hampering gaps between developers' requests of data and data providers' provision of data. This paper explores the benefits with open data assessment based on an exploratory single case research design.
