A CKAN resource view for DC (deformability cytometry) data, developed for the DCOR (Deformability Cytometry Open Repository) platform. The preview includes metadata from HDF5 attributes and a summary plot showing scatter plot of brightness vs. area along with image, contour, mask, and fluorescence data for one event. The extension implements a default view for DC mimetype resources, background jobs for generating and uploading preview images to S3 object store, a route for serving preview images, and CLI commands for batch processing. Available on PyPI.
