The last decade has seen a dramatic increase in attention from the scholarly communications and research community to open access (OA) and open data practices. These are potentially related because journal publication policies and practices both signal disciplinary norms and provide direct incentives for data sharing and citation. However, there is little research evaluating the data policies of OA journals. In this study we analyse the state of data policies for OA journals by employing random sampling of the Directory of Open Access Journals and Open Journal Systems journal directories and applying a coding framework that integrates both previous studies and emerging taxonomies of data sharing and citation. This study, for the first time, reveals both the low prevalence of data-sharing policies and practices in OA journals, which differs from the previous studies of commercial journals in specific disciplines.

评估和促进开放获取期刊中的开放数据实践

在过去十年中，学术交流和研究界对开放获取 (OA) 和开放数据实践的关注急剧增加。这些可能是相关的，因为期刊出版政策和实践既表明学科规范，又为数据共享和引用提供直接激励。然而，很少有研究评估 OA 期刊的数据政策。在这项研究中，我们通过对开放存取期刊目录和开放期刊系统期刊目录进行随机抽样，并应用一个编码框架来分析 OA 期刊的数据政策状态，该框架整合了以前的研究和新兴的数据共享和引用分类法。这项研究首次揭示了 OA 期刊中数据共享政策和实践的普遍性较低，
