| Περίληψη: | Numerous open data infrastructures are currently under development aiming to
stimulate the potential advantages of the publication and use of open government data. In
particular the development of open data infrastructures in the form of marketplaces, where
open data providers and open data users trade and share data and data services, can stimulate
the realisation of these advantages. Yet, only little research has been conducted on the
development directions of open data infastructures to realise such marketplaces. This study
aims to identify elements for the development of future electronic open data marketplaces.
This aim is attained by using a literature review and expert discussions, which resulted in the
following elements: 1) bring stakeholders together, 2) provide rich metadata, 3) enable data
quality assessment, 4) ensure trust, security and critical mass, 5) have an appropriate revenue
model, 6) provide use cases, training and support, 7) provide technical support: open data
tools, 8) provide a full API for machine-to-machine operation and 9) target multiple
nationalities. The results of this study can be used to develop and improve open data
marketplaces to stimulate the realisation of open data advantages. |
