Removal of files

Question

If the division requests that we remove all older files, we oblige. Does that mean these older files have to be removed from data servers as IDLS, Landru, Sherlock, etc... or is it only to be removed from the DLI ftp/web site?

Answer

If the division provides the DLI with a new data file and asks us to remove it from our FTP site it means that they do not want the older version in circulation. This is usually because there was an error on the original file or they revised the weights, or some other action that will produce different results. If the maintainers of systems like IDLS, Landru and Sherlock want to ensure that their users have access to the latest and most up to date data files and be able to produce results that will match those being poduced elsewhere it is strongly advised that they remove the older version and install one that is now the "official version".
