52 Such approach will encourage creation of community demand-led solutions allowing third parties (including the private sector) make the adjustments to final solutions for the application scenarios of various specific user groups, as well as to ensure constant compliance with the technological development. Availability of public data and availability of interfaces are preconditions to promote the implementation of potential of knowledge-based economy and sustainability of public ICT investments. 5.4.1.1 Opening of Public administration Data to Other Users Data and information owned by public administration is resource, which includes unrealised economic and social potential. Data value increases, by disclosing them, where they can be used in the development of new commercial products, in scientific and research work, the analysis of public process, which in form of GDP growth and tax revenue will positively impact not only national economy, but also directly – budget returns, where part of them may be used for the maintenance of public administration action direction and financing of further development, creating an opportunity to change public data potential into economic potential more progressively. Latvia does not have an adequate infrastructure to provide opening and publishing of comprehensive data existing in public sector, including in a machine-readable format. The legal framework provides demand-based data reception of public data, rather than proactive publication for the re-use. According to the European Public Sector Information Platform data, nearly no measures to promote the use of open data (information on available data sets, educational and solution-creation facilitating measures and initiatives) have been introduced in Latvia. With this in mind, the current rating of public sector information re-use is 285 points out of a maximum of 700.40 Assessment has been comprised of implemented preconditions such directions as the takeover, re-use practices, formats, fees, exclusive arrangements, local (municipal) data re-use, re-use promotion measures regarding European Parliament and Council Directive 2003/98/EC on the re-use of public sector information (PSI Directive)41. To use the potential of public sector data, a series of measures should be introduced in order to make public administration data technically and legally available, to publish them proactively, as well as promoting their exploitation in the creation of new solutions. Taking into account measures envisaged in the future action plan, it is predicted that in 2017 the evaluation of public sector information for re-use will reach ~ 380 points, which will be achieved through the measures at least in the following areas: 1. Implementation of European Parliament and Council Directive 2003/98/EC on the re-use of public sector information (PSI Directive) – is considered to be finished and it is expected to take the updated directive; 40 European PSI Scoreboard http://epsiplatform.eu/content/european-psi-scoreboard European PSI Scoreboard methodology: http://www.scribd.com/fullscreen/116277657?access_key=key2681s8l1i37otu6dyvzd&allow_share=true&view_mode=scroll information_society_development_guidelines_2014_2020.docx; Information Society Development Guidelines 2014-2020 41
