Analysing the Characteristics of Open Government Data Portals in Croatia

Open government data (OGD) paradigm gained momentum in the recent years resulting in numerous OGD initiatives. These initiatives assured reliable and faster development of open data ecosystem on different administration levels. Diversity of government organizations dealing with different kinds of data, however, resulted in a variety of OGD initiatives. As a direct result, OGD portals developed through these initiatives show different functionalities, characteristics, and quality of provided data and services. This paper therefore aims to provide a better insight into the similarities and differences of data portals by analyzing their characteristics from thematical, semantical, functional, and technological perspective. The methodology used relies on the framework previously developed and implemented in Greece in 2015, consisting of multiple indicators assessing different characteristics of portals, in each of four perspectives. Results of the assessment show Croatian portals have well developed functionalities but also have limitations preventing data reuse. These limitations are mostly related to data discovery and absence of metadata and licenses by the publishing institutions.开放政府数据（Open Government Data, OGD）范式近年来势头迅猛，催生了大量OGD相关实践项目。此类项目保障了不同行政层级下开放数据生态系统的可靠快速建设。然而，由于负责处理各类数据的政府机构类型多样，进而催生了形式各异的OGD实践项目。由此直接导致，通过这些项目搭建的OGD门户在功能、特性以及所提供数据与服务的质量层面均存在差异。因此，本研究旨在从主题、语义、功能与技术四个维度分析数据门户的特性，以更深入地剖析其异同之处。本研究采用的方法论依托2015年于希腊开发并落地的评估框架，该框架包含多组评估指标，可从上述四个维度分别对数据门户的各项特性进行评估。评估结果显示，克罗地亚的各类数据门户功能完善，但同时存在阻碍数据复用的缺陷。此类缺陷主要与数据发现功能不足，以及发布机构未提供元数据与授权许可相关。
