Many processing goals use the Delimiter-separated Values (DSV) format documented below.
DSV format stores a number of entries with multiple fields.
Class|File spam|spam1.txt nonspam|other.txt spam|spam2.txt
Fields are identified by their header, so the following would be equivalent:
File|Class spam1.txt|spam other.txt|nonspam spam2.txt|spam
This format is very similar to the CSV format common on Windows and the
format used on Unix systems for files such as
/etc/password. Main differences are the use of a pipe as field separator
and the identification of fields by header instead of position.
