File Formats and Metadata
File-level metadata is the information required for ADS to archive and disseminate files within a larger dataset, this will commonly include notes on the software used, lists of file names, and contextual information. Required file-level metadata will differ dependent on data type and for each data type, only certain types of file formats are accepted.
Preferred file formats are open stable formats suitable for preservation (may be converted to a more accessible web format for dissemination). Whereas acceptable file formats may be sufficient for dissemination, but need work to convert into a preservation-suitable format and may need more extensive curation in the future.
