HDF5[1]和NeXus[2]（通常使用HDF5作为其底层格式）被广泛吹捧为存储Photon和Neutron数据的标准。与其他常见格式相比，它们具有许多优点，并在许多设施中广泛使用。然而，人们发现，这些标准的现有实现限制了一些最近的探测器系统的性能。本文描述了同步加速器光源社区如何与HDF集团密切合作，推动HDF5软件的变化，使其更适合他们的环境。这包括检测器制造商管理的开发（Dectris用于直接块写入）以及同步加速器（DESY， ESRF和Diamond用于可插拔滤波器，单写入器/多读取器和虚拟数据集）。
HDF5[1] and NeXus[2] (which normally uses HDF5 as its underlying format) have been widely touted as a standard for storing Photon and Neutron data. They offer many advantages to other common formats and are widely used at many facilities. However, it has been found that the existing implementations of these standards have limited the performance of some recent detector systems. This paper describes how the synchrotron light source community has worked closely with The HDF Group to drive changes to the HDF5 software to make it more suitable for their environment. This includes developments managed by a detector manufacturer (Dectris for direct chunk writes) as well as synchrotrons (DESY, ESRF and Diamond for pluggable filters, Single Writer/Multiple Reader and Virtual Data Sets).
