When we are working on camera trap data loading, we noticed some of the files are lost during the ingestion. We first tried on the smallest set (12 images only), using the sidora web interface for resources uploading. 6 of the 12 images are lost during ingestion. Then we tried to upload the image files to fedora directly. There are still lost files, about 1 out of 15 images are lost. Also, the ingestion is very slowly. For the second test set (996 images), it has taken several hours already but it is still not finished.
