The data and metadata which are gained as JCAMP-DX and JSON are brought together in the form of a BagIt container. If ChemConverter is embedded into the Chemotion ELN, the BagIt container is generated as soon as the data from a device is available on the ELN server (and visible in the inbox). The processed data (as original input and converted BagIt container) are visible within the inbox of the ELN and can then be assigned to the samples. The BagIt container is a well-defined hierarchical file packaging format , consisting of different elements that contain data and its description. In our implementation (Figure ), the BagIt container contains a "bagit.txt" file, a data/payload subdirectory and two manifest tag files (sha256 and sha512) that include a checksum for each file in the payload directory. In case of the BagIt's CV output, the payload data directory contains different converted JCAMP-DX files, each the result of an extracted and converted CV cycle from a single input file. Additionally, the BagIt container contains a directory named metadata, which consists of a JSON file with the sum of all extracted metadata of the whole CV experiment.
