Description
HDF5 (with NeXus) is becoming the standard in many X-ray facilities. HDF5 viewers are needed to allow users to browse and inspect the hierarchical structure of HDF5 files, as well as visualize the datasets inside as basic plots (1D, 2D). Having such a viewer on the web is especially interesting since it allows users to browse files remotely without having to install anything locally.
To answer these needs, we developed H5Web at the ESRF, in open source, with the aim of providing easy access to HDF5/NeXus files and high interactivity with performant WebGL visualisations.
Thanks to its high modularity, H5Web can now be used to view HDF5 files:
- in JupyterLab
- Visual Studio Code
- in the browser via myHDF5
- internally, in the ESRF data portal
- and in many other software at other research institutes and private organisations.
In this presentation, I'll report on the recent progress of the H5Web project as a whole: how we worked to remove the size limit for local files in the browser, to bring the support of compression filters in the browser and how we try to answer general requests on the viewer itself.
This project has received funding from the European Union's Horizon 2020 research and innovation program under grant agreement No. 823852.
