HEPData 2.0: new technologies and services

现代高能粒子物理实验数据的成功解释是一个复杂的过程，不仅涉及实际测量，还涉及各种理论或现象学模型和过程的输入，当然，这些模型和过程依赖于先前的数据。杜伦大学粒子物理研究所的高能粒子加速器数据项目将继续收集来自世界各地粒子物理实验的高能粒子加速器散射数据，并将这些数据免费公开。它将使这些数据易于获取，从而将它们推广给更广泛的受众。除其他外，HEPData中的数据可用于规划和解释新的测量结果，根据新的发现重新解释旧数据，对理论模型进行精度测试，提取基本参数或其极限，以及调整和验证模拟工具。通过与粒子物理学的中央出版数据库Inspire更好地集成，HEPData将提供一个大大改进的已发表数据的持久开放访问存储库，作为粒子物理学的活记忆。HEPData最终将成为新兴的INSPIRE合作的正式成员，该合作目前由CERN， DESY， SLAC， FERMILAB和IHEP在中国组成，因此将代表英国粒子物理社区在全球粒子物理数据保存策略的一个方面。这种整合的效果之一是，训练有素的物理学家管理HEPData的宝贵时间将被释放出来，用于数据管理的中心和重要方面，用于进一步发展和扩大HEPData的范围。这将包括扩展新的HEPData - inspire框架相对于旧的HEPData数据库的能力，例如，通过允许包含尚未成为期刊出版一部分的支持材料，通过允许与基本分析软件交叉链接，从而为数据持久性提供更集成的愿景，以及通过为实验人员提交数据添加其他模式和格式。此外，我们计划扩大HEPData的范围，纳入来自粒子衰变或低能或天体粒子实验的数据，并包括与探测器模拟建设相关的数据。为这类数据提供存储库也将有助于其他科学领域，如材料科学、空间科学或医学物理学。HEPDATA还将继续为帕顿分布函数（PDF）代码提供服务器，并维护和改进绘制它们的设施。它将参与开发和维护LHAPDF，这是一个新的pdf库，用于当前和未来的分析。

The successful interpretation of data from modern high-energy particle physics experiments is a complex process involving not only the actual measurement but also the input of a variety of theoretical or phenomenological models and processes, which, of course, rely on previous data. The HEPData project at the IPPP Durham will continue to compile HEP Experimental scattering data from particle physics experiments around the world and make these freely and openly available. It will keep these data easily accessible and thus promote them to a wider audience. The data in HEPData allow, among others, the planning and interpretation of new measurements and the re-interpretation of older data in light of new findings, precision tests of theoretical models and the extraction of fundamental parameters or their limits, and the tuning and validation of simulation tools.Through a better integration with Inspire, the central publication database of particle physics, HEPData will provide a vastly improved persistent open-access repository of published data, serving as the living memory of particle physics. HEPData will eventually become a formal member of the emerging INSPIRE collaboration, which currently consists of CERN, DESY, SLAC, FERMILAB and IHEP in China, and will thus represent the UK particle physics community in one aspect of the global data preservation strategy in particle physics. One of the effects of this integration is that valuable time of the trained physicist managing HEPData will be freed for central and important aspects of data curation, for further developments and for a broadening of the scope of HEPData. This will include extending the abilities of the new HEPdata-Inspire framework with respect to the old HEPData database, for instance by allowing the inclusion of supporting material that has not been part of the journal publication, by allowing cross linking with essential analysis software, thus providing a more integrated vision for data persistence, and by adding other modes and formats for data submission by the experimenters. In addition, we plan to broaden the scope of HEPData, to incorporate also data from particle decays or low-energy or astro-particle experiments, and to include also data relevant for the construction of detector simulation. Providing a repository for such data will also be useful for other fields of science, such as material science, space science, or medical physics.HEPDATA will also continue to provide a server for Parton Distribution Function (PDF) codes and maintain and improve facilities for plotting them. It will take part in developing and maintaining LHAPDF, the new library of PDFs for use in current and future analyses.
