Creating an archive file
A dataset to be processed should always be delivered as a compressed file, also known as an archive or ZIP file. If datasets are submitted according to the XML formats BMEcat 2005 ETIM V4.0 and V5.0, DICO (SALES and INSBOU), these files should be valid.
Archiving files with Windows
In general, the Windows operating system offers the option of compressing multiple files (packaging them) as a ZIP file. There are also alternative tools available such as 7ZIP and PKZip. The extension of a compressed file is .zip, .gz of 7z.
Archiving files with UNIX
Many UNIX-based operating systems use GZIP. One feature of the GZIP protocol is that only one file can be packaged at a time. TAR allows you to archive multiple files into a single file. 2BA supports only files, even if it concerns a single file, that has been first archived with TAR and then packaged with GZIP. The following two are the extensions permitted: .tar.gz en .tar.gzip. A second restriction is that path names may not be included in the TAR archive.
