55 During further implementation, the priority “openable” data sets will be identified, which will be included in the list of the thematic direction’s priority projects. Additionally, criteria and qualification requirements will be developed, according to which any institution any institution that holds the data will be able to claim the co-financing of EU Structural funds for opening of these data. Also, when implementing open data principle, it will be necessary to formulate conditions for public administration data usage. Generally they are determined by different types of licences. Although open data in general sense are defined as freely accessible and usable, they may be subject to licensing conditions, which, for example, determine reference conditions, etc. In order to create as uniform as possible and also internationally recognisable licensing practice, it is necessary to consider a possibility to use one of the public licensing policies recognised in European or international level (such as Creative Commons Licenses43, European Union Public Licence44). 5.4.1.2 Opening of Public administration Transaction Services to Other Users Administrative procedures are one of the most important forms of communication between inhabitants, entrepreneurs and the state. Public administration services should be available to inhabitants in such format and context as they need – it may not always be a state website. Eservices potentially may be provided by the partner organisations as well (such as NGOs or a merchant). Most of e-services are implemented in a way where data and interface layers are not separated, which makes it impossible to use existing data or processes in order to create interfaces adapted to specific user needs. This approach does not provide compliance of eservices solutions to the latest technology options. Required Actions In order to ensure sustainability of service compliance to latest technology trends and to create the opportunity to provide them integrally with the help of private sector services or to facilitate their use, for example, in local governments e-services may be developed to build application programming interfaces (APIs), by separating the e-services functional and graphical interface. Unlike open data – massive data discharge, these solutions will provide an opportunity to build personalised e-services and data transfer solutions also outside public administration. In order for this approach to be successfully implemented, it is necessary to plan the centralised and shared solutions for the deployment of such interfaces, define their standards, as well as to create governance and quality assurance strategies of the API-based solutions. Such an approach would facilitate the switch to more cost-effective digital service channels (channel shift) which will create an ecosystem that supports public and private sector services symbiosis (integrated solving of user needs (for example, the opportunity to apply for credit service, in the same time allowing to obtain data on earnings, etc.), usage of single technical solutions, common user training and education, etc.). The solutions of the above mentioned objective should be created so that they could be used in other institution and local governments, private sector; therefore avoiding duplicate costs. Also, it is important to implement measures 43 http://creativecommons.org/licenses/ https://joinup.ec.europa.eu/software/page/eupl information_society_development_guidelines_2014_2020.docx; Information Society Development Guidelines 2014-2020 44
